WEP001	Configuration and Sequencing Tools for the LMJ Control System	409
	J. I. Nicoloso, J. J. Dupas CEA, Arpajon J. C. Picon, F. P. Signol CESTA, Le Barp
	This presentation describes two of the main functions of the common framework which underlies the Laser MegaJoule (LMJ) supervisory software: configuration and sequencing. The configuration manager allows creating a model of the system under control, and making it available for the different parts of the command-control software. The system is described as a hierarchy of objects linked by different types of relationships, which are used by the command-control software to propagate events, alarms, states and actions. The model acts also as a centralised repository for all of the parameters and characterisation data needed to control the process. Concerning sequencing, it is one of the major functions used to operate the LMJ facility. Specialized software tools were designed to develop and execute the programs that schedule the hundreds of actions needed to perform shot sequences. Sequence programs are described as state machines and VB scripts which are then embedded into the PANORAMA supervisory software that executes them in a distributed manner. Objects, properties and functions of the PANORAMA applications are made available from the scripts through specialized API.
WEP002	BEPCII EPICS Data Archiving and Retrieving System	411
	Z. Zhao, S. Liu, C. H. Wang IHEP Beijing, Beijing
	IHEP has installed the BEPCII project that has been funded by the Chinese Government in order to further upgrade the BEPC (Beijing Electron Positron Collider) which has operated since 1989. As a part of this updating project, control system is decided to use the Experimental Physics and Industrial Control System, EPICS. The Channel Archiver is an archiving toolset for EPICS. It can archive any EPICS channel value that is available via ChannelAccess (CA), the EPICS network protocol. The paper will introduce how to establish EPICS data archiving and retrieving system in BEPCII. It will talk about how to configure and use Channel Archiver and Archive Viewer software based on HP Server and Disk Array platform.
WEP004	Web Services for APS Control Systems Relational Database Software: Tying It All Together	1
	D. E.R. Quock ANL, Argonne
	Funding: Work supported by the U. S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under Contract No. DE-AC02-06CH11357. The use of relational databases at Argonne National Laboratory's Advanced Photon Source (APS) for managing extensive and diverse control systems content is found in several different applications that are built with various types of software technology. Two heavily used, operations-mission-critical database applications at APS are the Integrated Content Management System (ICMS), an Oracle commercial product that is used primarily at APS for document management, and the Integrated Relational Model of Installed Systems (IRMIS), originally designed and developed by APS controls scientists and engineers with open source software for capturing as-built information about the particle accelerator control systems. To meet the objectives of minimizing data redundancy, automating data transfer, and providing efficient and accurate data mining among database applications, Web Services technologies options have been explored as a means of tying IRMIS and ICMS together. This paper describes the use of Simple Object Access Protocol (SOAP), an XML-based messaging protocol for executing code on remote systems, as a means for seamlessly interfacing two different types of database technologies.
WEP005	The LHC Logging Service: Handling Terabytes of On-line Data	414
	C. Roderick, R. Billen, R. D. Gaspar Aparicio, E. B. Grancher, A. Khodabandeh, N. Segura Chinchilla CERN, Geneva
	Based on previous experience with LEP, a long-term data logging service for the LHC was developed and put in place in 2003, several years before beam operation. The scope of the logging service covers the evolution over time of data acquisitions on accelerator equipment and beam related parameters. The intention is to keep all this time-series data on-line for the lifetime of LHC, allowing easy data comparisons with previous years. The LHC hardware commissioning has used this service extensively prior to the first beams in 2008 and even more so in 2009. Current data writing rates exceed 10TB/year and continue to increase. The high data volumes and throughput rates, in writing as well as in reading, require special arrangements on data organization and data access methods.

WEP006	The LSA Database to Drive the Accelerator Settings	417
	C. Roderick, R. Billen CERN, Geneva
	The LHC-era Software Architecture (LSA) used to operate the particle accelerators at CERN is dependent on an online database to manage both high and low level parameter settings, including their evolution over time. Accelerator optics models, control sequences, reference values, are amongst the other entities being managed within the database. The LSA database can be considered as being located between the operators and the accelerators; therefore performance, availability, and security of the service as well as data integrity are paramount. To meet these requirements the LSA database model has been carefully developed, all database access is tightly controlled and instrumented, business logic is implemented within the database, and there is a semi-automatic integration with other key accelerator databases. Currently 7 million settings for some 40 thousand devices of the LEIR, SPS, and LHC accelerators are being effectively managed.

WEP007	FESA 3.0: Overcoming the XML/RDBMS Impedance Mismatch	420
	M. Peryt, M. Martin Marquez CERN, Geneva
	The Front End System Architecture (FESA) framework developed at CERN takes an XML-centric approach to modeling accelerator equipment software. Among other techniques, XML Schema is used for abstract model validation, while XSLT drives the generation of code. At the same time all the information generated and used by the FESA framework is just a relatively small subset of a much wider realm of Controls Configuration data stored in a dedicated database and represented as a sophisticated relational model. Some data transformations occur in the XML universe, while others are handled by the database, depending on which technology is a better fit for the task at hand. This paper describes our approach to dealing with what we call the "XML/Relational impedance mismatch" - by analogy to Object/Relational impedance mismatch - that is how to best leverage the power of an RDBMS as a back-end for an XML-driven framework. We discuss which techniques work best for us, what to avoid, where the potential pitfalls lie. All this is based on several years of experience with a living system used to control the world's biggest accelerator complex.

WEP009	ALBA Control & Cabling Database	423
	D. B. Beltran, I. Costa, D. Fernandez-Carreiras, J. V. Gigante, J. Klora, V. Prat, R. Ranz, J. Ribas, S. Rubio-Manrique, A. Ruz, O. Sanchez CELLS-ALBA Synchrotron, Cerdanyola del Vallès
	CELLS has developed a database as a main repository for the cables and control devices in the ALBA facility. Regarding cables, the database has all the information about the cable configuration (cable and connectors on both sides) and routing (trenches and cable length) as well as the devices where the cables are plugged in. The dabatase performs two checks before uploading a cable: the connector on the equipment and on the cable match, a cable was not connected yet to that equipment. The cables have different status, according to their installation process (received, installed, tested OK, tested error, etc). Regarding control devices, the database has all the information about the devices (serial numbers of computers and boards, DHCP address) and tests done (Operation system, drivers and Tango). This database has a friendly web interface for user access. It allows many types of filters for cable & devices: location in the tunnel or in the racks, by system (SR, Booster, BL1, …), by routing (name of trench).
WEP010	Validation of a MySQL-based Archiving System for ALBA Synchrotron	426
	S. Rubio-Manrique CELLS-ALBA Synchrotron, Cerdanyola del Vallès M. Ounsy, S. Pierre-Joseph Zephir SOLEIL, Gif-sur-Yvette G. Strangolino ELETTRA, Basovizza
	ALBA Synchrotron collaborates with SOLEIL and ELETTRA institutes in the improvement of the Archiving System for Tango. An open source Database engine (MySQL) has been chosen and the viability and limitations of a MySQL-based Archiving System have been evaluated in a test platform. Using Java-based data collectors both centralized and distributed architectures have been tested. It allowed to demonstrate the maturity of the system, being achieved the most critical requirements.
WEP011	Automated Experimental Data Analysis at the National Ignition Facility	429
	S. G. Azevedo, R. G. Beeler, R. C. Bettenhausen, E. J. Bond, P. W. Edwards, S. M. Glenn, J. A. Liebman, J. D. Tappero, A. L. Warrick, W. H. Williams LLNL, Livermore
	Funding: This work performed under the auspices of the U. S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. The National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory is a 192-beam 1.8 MJ ultraviolet laser system designed to support high-energy-density science, including demonstration of inertial confinement fusion ignition. After each target shot lasting ~20 ns, scientists require data acquisition, analysis, and display within 30 minutes from more than 20 specialized high-speed diagnostic instruments. These diagnostics measure critical x-ray, optical, and nuclear phenomena during target burn to quantify ignition results that are compared to computational models. All diagnostic data (hundreds of Gbytes) are automatically transferred to an Oracle database that triggers the NIF Shot Data Analysis (SDA) Engine, which distributes the signal and image processing tasks to a Linux cluster. The SDA Engine integrates commercial workflow tools and messaging technologies into a scientific software architecture that is highly parallel, scalable, and flexible. Results are archived in the database for scientist approval and displayed using a web-based tool. The unique architecture and functionality of the SDA Engine will be presented along with examples.

WEP012	Application of MDSplus for the Management of the Pulsed-based Experimental Data in KSTAR Tokamak	1
	T. G. Lee, S. Lee, M. K. Park NFRI, Daejon
	Different from the accelerator to operate continuously, the KSTAR as a tokamak device which has features of continuous operation and shot-based pulse operation has different types of data generated. One is a continuous plant data coming from a vacuum monitoring system, a tokamak monitoring system, and this data is archived with EPICS channel archiver. The other is a shot-based experimental data generated only for a plasma discharge shot. This type of data is archived using MDSplus which is widely used in the fusion environment. In the category of the experimental data, every diagnostics data, heating parameters and real-time plasma feedback data belong here. Besides MDSplus, EPICS channel archiver is partially used to archive the configuration parameters of DAQ systems and shot information. Because experimental data are transferred to a central storage after the completion of a discharge shot, low-speed run-time data is archived in duplicate using EPICS channel archiver to monitor plasma during a shot. This paper will present the application of MDSplus for management of pulse data from tokamak device in conjunction with EPICS channel archiver according to the applications.

WEP013	Application of a Simple Text Format as a Device Configuration File	432
	T. T. Nakamura KEK, Ibaraki
	In the KEKB magnet control system, relational database management system (RDBMS) has been used for the management of the device configuration. Most of the device parameters, such as address of the interfaces, constant parameters of the magnet power supplies, excitation functions of the magnets, limit values for the operation, etc. are stored in the RDBMS. These parameters are used mainly for the macro expansion to generate the runtime EPICS database files. They are also used to configure the high level application programs. Although this scheme is flexible, it is heavy to maintain with little man power in the KEKB control group. To reduce the maintenance cost, restructuring of this scheme is planned. The plan consists of two major changes. One is the reducing data and making data structure simpler. Another is the replacing tools with simpler ones. As the part of the restructuring, the replacement of the RDBMS with a simple configuration files is planned. The configuration file has simple text format, which is designed easy to read and easy to modify only using text editor. The detailed design of the format and its application to the KEKB magnet control system are presented.

WEP014	Two-level Channel Model in Three-level Control System	1
	S. E. Karnaev, D. Bolkhovityanov, P. B. Cheblakov, Y. I. Eidelman, A. V. Makeev BINP SB RAS, Novosibirsk
	The modern classical architecture of a control system includes three levels: client application level, server level for synchronization of data exchanges and hardware level, which includes hardware drivers. There are two different types of data exchange in the three-level control: between client and server levels and between server and hardware levels. The concept of "channel" maintains the both types of data exchange. The channel implementation connects a physical characteristic of a controlled facility (in the client level) with a corresponding value in an electronic device. The presented paper describes a two-level channel model, which includes the difference between the data exchange types. The two-level channel model separates the specific attributes of the data exchange types and provides a flexible interface between a physical characteristic of a facility and an implementation of electronics. The model includes two levels of channels: client channels connected with facility physical characteristics and hardware channels connected with electronics. A description of channel types, relations between two levels and an exchange protocol project are presented in this paper.
WEP015	Grid-enabling the Astra Gemini Laser Data	435
	E. J. Divall, M. T. Gleaves, K. Hayrapetyan, A. Kidd, L. Lerusse, V. A. Marshall, S. Nagella, D. Neely, M. M. Notley, A. A. Pakhira, L. Sastry STFC/RAL, Chilton, Didcot, Oxon
	Astra Gemini is a dual beam Ti:Sapphire laser capable of delivering up to 0.5 PW in each of its two beams. The system can fire once every 20 seconds (producing over 10⁰⁰ shots per day) and has over 200 diagnostic channels, including spectra, pulse length, traces, near and far-field images. This combination of multiple diagnostics and high shot rate leads to an unprecedented amount of performance and diagnostic data to save and analyse. To cope with this demand a system has been developed to automatically capture and analysis laser data on every shot, store it in an Oracle database and retrieve it on demand. A graphical user interface has been written to extract, sort and display the data in a tabular form. Powerful functions have been implemented to allow any parameters to be selected and plotted against one another to analyse performance trends and fluctuations. Metadata about each diagnostic can also be input to build a holistic picture of the laser system and help with future analysis. To increase the value it is planned to incorporate the target area experimental diagnostics into the system and make the data available to participating experimenters anywhere around the world.* * http://www.clf.rl.ac.uk/reports/2007-2008/pdfs/s7/ar07-08_s7_commisioning_the_south_beam.pdf ** http://www.clf.rl.ac.uk/reports/2007-2008/pdfs/s7/ar07-08_s7_eclf_project_progress.pdf

WEP017	Design of an XFEL Beamline DAQ System	438
	T. Ohata, Y. Furukawa, T. Hirono, R. Tanaka, A. Yamashita JASRI/SPring-8, Hyogo-ken T. Hatsui, T. Ishikawa, M. Yabashi RIKEN/SPring-8, Hyogo
	We have designed the control and the data acquisition system for the SPring-8 XFEL beamlines. The XFEL generates ultra-short pulsed coherent X-ray laser with the 60Hz beam repetition rate. Two-dimensional x-ray detectors are under development for X-ray detection. The data acquisition system for the detectors has to synchronize with the accelerator beam operation cycle to obtain correlations between incident X-ray and experimental data. The tagging system that records event numbers in the measurement data is especially important. The key technologies to make a success of the DAQ system of XFEL beamline are a tagging system of the 60Hz X-ray pulse, a real-time compression of fast massive data and low-latency network for data transfer. Both the network system of 3~4 Gbps bandwidth and the storage system with a near petabyte will be required in the initial operation phase of the XFEL project. At first, we developed a FPGA based tagging board that delivers tag numbers of X-ray pulse shots with parallel and serial interfaces. A first test system will be assembled by early 2010.
WEP018	Software Applications for the Commissioning of the LHC Superconducting Circuits	1
	A. Vergara-Fernández, B. Bellesia, M. Pojer, A. Rijllart, R. I. Saban, R. Schmidt, M. Solfaroli Camillocci, J. Szkutnik, M. Zerlauth CERN, Geneva C. Fernandez-Robles, A. Marqueta Barbero IBERINCO, Madrid
	During the 2008 Hardware Commissioning phase of the Large Hadron Collider, the 1572 superconducting circuits of the accelerator were individually tested at different current levels before being released for operation with beam. Almost 12,000 tests had to be carried out in about six months, the performance of the different circuits analysed and the results stored. In order to cope with the schedule, manpower constrains and huge complexity of the systems under test, a set of software tools was developed during the last two years in order to automate as much as possible the preparation, execution, analysis and tracking of the tests. This paper outlines the different tools developed, describes their integration amongst themselves and within the whole Hardware Commissioning Project and details the overall performance and positive impact they have had on the different actors involved in these powering tests.
WEP019	Crawling the Control System	441
	T. L. Larrieu JLAB, Newport News, Virginia
	Funding: Authored by Jefferson Science Associates, LLC under U. S. DOE Contract No. DE-AC05-06OR23177. Information about accelerator operations and the control system resides in various formats in a variety places on a lab network. There are operating procedures, technical notes, engineering drawings, and similar formal controlled documents. There are programmer references and API documentation generated by tools such as doxygen and javadoc. There are the thousands of electronic records generated by and stored in databases and applications such as electronic logbooks, training materials, wikis, and bulletin boards and the contents of text-based configuration files and log files that can also be valuable sources of information. The obvious way to aggregate all these sources is to index them with a search engine that users can then query from a web browser. Toward this end, we evaluated open source search engine software, "Oracle Text", and the Google "mini" search appliance. We chose to implement the Google 'mini' because of its low cost and simple web-based configuration and management. The presentation will s some pros and cons of different search engine choices we evaluated and what we have learned from our experience configuring and using the Google "mini" search appliance. The U. S. Government retains a non-exclusive, paid-up, irrevocable, world-wide license to publish or reproduce this manuscript for U. S. Government purposes.
WEP020	Life Cycle Management System for Accelerator Equipment	444
	Y. Ishizawa, A. Yamashita JASRI/SPring-8, Hyogo-ken
	We have developed life cycle management system for accelerator equipment. It manages whole life cycle of equipment used in accelerators from production to scrapping. The key component of the system is labels two dimensional bar code (QR-code) sticked on equipment at the production time. A dedicated device reads ten digit serial number on the label at every event on the equipment i.e. production, delivery, temporary stock, installation, repair, re-installation and scrapping. Labels sticked on wall or floor of the building manages the location of equipment. A relational database management system (RDBMS) stores data. Users can access data from the web interface. Web based GIS (Geographic Information System) provides interactive map to display location of equipment. Documentations on equipment are also manged by the RDBMS. We present the design, implementation and operation of the system.
WEP021	A MySQL Based EPICS Archiver	447
	C. J. Slominski, M. Bickley JLAB, Newport News, Virginia
	Funding: Notice: Authored by Jefferson Science Associates, LLC under U. S. DOE Contract No. DE-AC05-06OR23177. Archiving a large fraction of the EPICS signals within the Jefferson Lab (JLAB) Accelerator control system is vital for postmortem and real-time analysis of the accelerator performance. This analysis is performed on a daily basis by scientists, operators, engineers, technicians, and software developers. Archiving poses unique challenges due to the magnitude of the control system. A MySQL Archiving system (Mya) was developed to scale to the needs of the control system; currently archiving 58,000 EPICS variables, updating at a rate of 11,000 events per second. In addition to the large collection rate, retrieval of the archived data must also be fast and robust. Archived data retrieval clients obtain data at a rate over 100,000 data points per second. Managing the data in a relational database provides a number of benefits. This paper describes an archiving solution that uses an open source database and standard off the shelf hardware to reach high performance archiving needs. Mya has been in production at Jefferson Lab since February of 2007.
WEP022	Timing Delay Management Database for J-PARC Linac and RCS	450
	H. Takahashi, H. Yoshikawa JAEA/J-PARC, Tokai-Mura, Naka-Gun, Ibaraki-Ken H. Sakaki JAEA, Kyoto M. Sugimoto Mitsubishi Electric Control Software Corp, Kobe
	J-PARC Timing System is defined two kinds of timing, scheduled timing and synchronization timing. The scheduled timing is defined by a delay determined in advance from the reference trigger sent from the central timing control. Most devices and power supplies run with the scheduled timing. The scheduled timing system is configured one transmitter module in central control room and many receiver modules in device installed rooms (in total more than one hundred modules). Three signals which are the master clock, the reference trigger clock and the type, and LUT (Look-up Table) are distributed to the all receiver modules from transmitter module. An LUT is delay data block which is 256 * 8 array (The "256" is the number of "type", the "8" is the number of "trigger fan-out" per one receiver module). Then, a great number of "delay data" have to be managed for accelerator operation. The paper presents about the database to manage the timing delay for Linac and RCS. 3GeV Rapid Cycling Synchrotron
WEP023	Correction of Phase and Amplitude Error of RF Modulator and Demodulator	453
	T. Ohshima, N. Hosoda, H. Maesaka, S. Matsubara, Y. Otake RIKEN/SPring-8, Hyogo M. Yamaga JASRI/SPring-8, Hyogo-ken
	The XFEL/SPring-8 project is in progress. SASE in X-ray region requires a high peak current of 3 kA, which will be achieved with an extremely stable rf accelerating field. In most severe case, the acceptable error in an rf phase is extremely small, such as 0.01 degree in root mean square. To make a stable rf field, we developed a high-speed DAC/ADC and an IQ modulator/demodulator to control/detect the low level rf signals. Modules with high setting/detecting accuracy are one precondition to achieve good stability. But the developed modules could have offset and gain errors because of the requirement of the high-speed operation. So we made the calibration method using a network analyzer to correct the errors. By using this method we could reduce the phase error of the C-band IQ modulator from 0.5 degree p-p to 0.1 degree p-p, for example. In this paper the detail of the calibration method and its performance will be shown.

WEP024	Development of Microcontroller-based Computer Interface Board and Local Display Unit for Steering Magnet Power Supplies	1
	K. Datta, S. Bandyopadhyay, C. Datta, D. Sarkar DAE/VECC, Calcutta S. Bhagwat BARC, Mumbai
	A microcontroller-based computer interface board and a local display unit have been designed and developed to monitor and control the power supplies from local panel as well as from the remote console. The main objective of this development is to provide support for the computer control of the indigenously developed bipolar X-Y steering magnet power supplies for the injection line of the K=500 Super Conducting Cyclotron at VECC, Kolkata. The interface board is designed around an Intel 8051 microcontroller which is programmed with firmware of different tasks like setting the current of the power supply through 12-bit DAC, reading the output current of the power supply through 12-bit ADC and communicating with remote computer through an optically isolated RS 485 port following a customized command-response protocol. This facilitates the operation of 12 number of power supplies connected in a multi-drop fashion from a remote centralised control panel. Through the local front panel, a user can set the current of the power supply, monitor the output current and the status of the power supply.

WEP026	Design and Implementation of a Full-featured Distributed Synchronization System Using Commercial Hardware	459
	B. Kalantari, T. Korhonen PSI, Villigen
	Funding: Paul Scherrer Institute In large scale facilities like accelerators, synchronization is not only about triggering. Other aspects of synchronization, namely synchronous data acquisition and/or collection and data time-stamping are equally important. In this paper we first discuss the general synchronization requirements of modern accelerators and then describe our approach to address such requirements in PSI-XFEL project. In our XFEL test stand we have implemented a full-featured synchronization system by integrating off-the-shelf hardware into a distributed control system (EPICS). By full-featured we mean a unified mechanism which addresses all aforementioned synchronization requirements (triggering, synchronous data acquisition/collection, time-stamping). We describe in detail our method to achieve this and explain what software components we had to develop in addition to available control system software.
WEP027	System Integration Effort on MagViz a Liquid Explosive Detection Device	462
	M. Pieck, J. O. Hill, J. F. Power LANL, Los Alamos, New Mexico
	Funding: Funded by the U. S. Department of Homeland Security. LA-UR- 09-02350 Los Alamos National Laboratory (LANL) technologists have adapted Magnetic Resonance Imaging (MRI) technology from medical devices to create MagViz, a new diagnostic and imaging device distinguishing potential-threat liquids from the harmless substances that the public might take onboard an aircraft. The MagViz system is a new ultra-low-field MRI approach using (SQUIDs) Superconducting Quantum Interference Devices for data acquisition. Linked with a computer database, MagViz reliably identifies some 50 liquids from the chemical fingerprints of their dynamic response to polarization stimulus wavefoms. The underlying technology for MagViz has been developed for an experimental laboratory environment. A controls team took the individually developed, highly incoherant, multi-platform collection of hardware and software applications, and integrated them into a coherant system. This paper will describe the integration effort, the problems faced, and the lessons learned when integrating a large number of hetterogenous systems; I.e. polarization stiumulus waveform generation system, SQUID control system, conveyer belt, camera image acquisition, data analysis library, and user interface.
WEP028	Development of a Multi Functional Unit: Blanc4	465
	M. I. Ishii, T. Ohata JASRI/SPring-8, Hyogo-ken
	A beamline station control system in SPring-8 has been installing two types. One is a VMEbus system and another is a desktop PC-Based system. The VMEbus system was adopted to construct a flexible control system by combining VME modules. However, the VMEbus system is over engineering for a compact control system to handle a few I/O signals or a few motor axes. And the VMEbus system is hard to handle for beamline staffs who are not experts of control system. On the other hand, the desktop PC-Based system is relatively low-cost and suitable for small system. However, the system is inferior in stability and scalability to the VMEbus system. To construct a reliable, flexible, compact, low-cost and user-friendly system, we developed a multi functional unit, Blan4, that is a flexible embedded computer supporting COM Express basic form factor. A Blanc4 has two PCI slots and two PCI Express slots in just 1 U height. A Blanc4 can replace connector panels and signal conditioning boards customized for each control target. We report the Blanc4 assembling as a flexible multi functional unit.

WEP031	Development of a New Phase Detector for the APS Linac	468
	A. F. Pietryla, A. E. Grelick, W. E. Norum ANL, Argonne
	Funding: Work supported by U. S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under contract No. DE-AC02-06CH11357 An effort is being made to upgrade the Advanced Photon Source Linac rf phase detector system. The decision was made to replace the current phase measurement system, which is based on a Los Alamos designed analog vector detector module, with a digital I/Q method. As an initial step we reconfigured one of our current 8-channel, 14-bit ADC designs, originally developed for the storage ring beam position monitor system, to perform the I/Q sampling and the phase and magnitude computations. This paper discusses the current board design, proposed modifications to optimize the board for this application, and field programmable gate array design.

WEP032	PCI/cPCI Interface for PSI Power Supply Controller	471
	D. B. Beltran, F. Becheri, D. Fernandez-Carreiras, J. V. Gigante, J. Klora, L. Krause, M. Lipinsky CELLS-ALBA Synchrotron, Cerdanyola del Vallès
	CELLS has developed a PCI/cPCI interface for the PSI controller for Power Supplies. Those power supplies are used for the Storage Ring corrector magnets (for slow and fast orbit feedback) and the corrector magnets of the Insertion Devices. The hardware interface has a commercial IP carrier (either PCI or cPCI), the PSI PSCIP2 Power supply control module, and a in-house rackable transition module (conversion between the electrical signal of the PSI PSCIP2 module and the optical signal). On the software side, an existing driver for Linux 2.4 VME has been adapted and upgraded to 2.6 PCI. A Tango device server is also available for both Fiber optic links and serial Line.
WEP033	Using an IIDC/DCAM Camera for Beam Display and Analysis	474
	R. H. Olsen, D. M. Gassner, L. T. Hoff BNL, Upton, Long Island, New York
	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U. S. Department of Energy An IIDC/DCAM camera is used to image the RHIC beams as they pass through a hydrogen jet. The data is transferred over 1394 to a computer running linux. A software process on that computer collects the individual frames and packages them into parameters within the RHIC control system's Accelerator Device Object framework. This information is packaged to continuously update two primary types of clients: One type is responsible for near-real-time display of the images; useful in comfort displays, etc. The second is responsible for collecting data used in analysis of beam dynamics and properties like luminosity.
WEP034	Application of VEPP-4M Database for Analysis Radiation Resistance of Temperature Sensors on Base DS1631Z	1
	O. A. Plotnikova, V. Y. Chudaev, S. E. Karnaev BINP SB RAS, Novosibirsk
	The temperature system on base DS1631 has proved its reputation as simple and reliable. In how intense ionizing radiation the system can remains operational for a long time? To answer this question the set of temperature sensors was placed at the converter of VEPP and the measurements have been adding to our DB every minute during one month. A dose of ionizing radiation had been registering every 3 days. The results of this experiment are described in the article.
WEP036	Development of Software for Event System in KEK Linac	1
	S. Kusano, T. Kudou MELCO SC, Tsukuba K. Furukawa, M. Satoh KEK, Ibaraki
	The KEK Linac injects the electron and positron beams into the KEKB-LER, KEKB-HER, PF and PF-AR rings with four different characteristics. In order to improve the beam operation efficiency, we have planned the simultaneous top-up operation for the PF and KEKB. The fast beam switching mechanisms are being developed and installed. For those mechanisms, the linac parameters of timing and low-level rf phase should be controlled in the pulse by pulse of 50 Hz. In this paper, we will present the event timing system to the KEK Linac control system in detail.

	In the RIKEN RI beam factory project (RIBF), the accelerators are operated by the remote control system based on EPICS. On the other hand, for RIKEN Linear Accelerator (RILAC) of RIBF injector, the control system include not only EPICS-based controllers, but also handmade hard-wired controllers still in operation. It is required to replace the handmade hard-wired controllers with ones which can interface with the EPICS-based system on an ethernet interface. Since sequential logic control is not required on the controllers, costly Programmable Logic Controllers (PLCs) are not the appropriate candidate. To implement the low cost embedded controller in our system, we developed EPICS device support using asynDriver for PIC Network Interface Card (PICNIC). The characteristics of PICNIC is Microchip PIC16F877 based embedded I/O controller with a network interface, a serial port, DIO 8ch and AI 4ch. It is suitable to use this controller for simple control, such as on-off control using electromagnetic relay. In April 2009, we started to adopt PICNIC as one of the remote controller in RILAC control system. In our contribution, we report this system and present the status in detail. http://www.tristate.ne.jp/picnic-e.htm
WEP038	CompactPCI Express for Control Applications	480
	H. Kleines, M. Drochner, W. Erven, M. Ramm FZJ, Jülich
	CompactPCI (CPCI) is well established in control applications as a standard for industrial PCs and as a standard for front-end instrumentation, e.g. by means of the transparent optical PCI/CPCI Bridge MXI-4 from National Instruments. In both application areas increasing performance requirements ask for a replacement of the parallel CPCI bus by a backplane based on high speed serial links, similar to the replacement of PCI by PCIe in the desktop environment. CompactPCI Express (CPCIe) and its derivative PXI Express (PXIe) both provide a smooth and cost-efficient transition path from CPCI to high speed serial links on the backplane. Forschungszentrum Jülich has developed a CPCIe carrier board for CMC daughter modules that is compatible to the SIS1100 boards from company Struck Innovative Systeme. The CPCIe carrierboard is based on a single lane PCIe implementation with the PEX8311 ASIC from PLX. A development environment has been setup, that consists of crates from Schroff, CPUs from MEN and the transparent electrical PXIe/PCIe bridge MXI-Express from National Instruments. The design and application of the new board as well first experiences with the new technology are presented.

	Funding: SNS is managed by UT-Battelle, LLC, under contract DE-AC05-00OR22725 for the U. S. Department of Energy A timing system is a crucial subsystem of every accelerator, responsible for orchestrating the entire machine cycle by cycle. The current SNS timing system is based on the modified BNL solution which in turn is based on previous systems at other sites. The timing master is a collection of low functionality VME building blocks that are highly dependent on creative software to achieve the needed system functionality. The implementation technology of the whole system is backdated, making it impossible to build and maintain spares and boards for machine upgrades. At SNS we chose a roadmap which would allow a gradual upgrade of the timing system without having to redesign everything at once and yet provide a path for future modernization of the infrastructure. This paper presents progress on new timing master and receiver card, which will provide us with more flexible control and greater reliability by tremendously reducing the component count while still retaining compatibility with existing timing receiver units. The designs emphasize the use of FPGA technology in a way that simplifies the supporting software. The design of the system is a collaboration effort of ORNL and Cosylab.

WEP044	LXI Instrumentation, with EPICS IOCs, for Remote Waveform Monitoring & Analysis	1
	L. Shaw ZTEC Instruments, Albuquerque
	Off-the-shelf instruments based on the LAN eXtensions for Instrumentation standard (LXI) and with embedded EPICS input/output controllers (IOCs) are an ideal solution for many particle accelerator applications. These applications require responsive remote control and real-time waveform monitoring for critical accelerator systems. These instruments typically have the same feature sets and powerful analysis capabilities that today's high-end benchtop instruments have. With an embedded EPICS controller, the instruments easily integrate into the EPICS environment without the need for EPICS drivers or external controllers. LXI oscilloscopes and digitizers can perform advanced real-time waveform math and analysis using on-board FPGAs and DSP. The paper will detail an application at Oak Ridge's Spallation Neutron Source (SNS). At SNS, LXI EPICS oscilloscopes are being evaluated for waveform monitoring in injection and extraction kicker systems to perform real-time mask testing on the acquired waveforms.

WEP045	A Pico-Second Stable Clock and Trigger Distribution System for the European XFEL	489
	P. Gessler, K. Rehlich DESY, Hamburg C. Bohm, A. Hidvegi Stockholm University, Stockholm
	For the operation of the European X-Ray Free Electron Laser (XFEL), a system wide synchronous low-jitter clock and precise, adjustable triggers must be generated and distributed throughout the 3.5 km long facility. Consumers are numerous diagnostics, controls, and experiments. Fast ADCs require the jitter of a distributed 1.3GHz clock to be in the order of a few pico seconds (RMS) and synchronized to the accelerating RF. Due to cable lengths, and the temperature dependence of the propagation speed, temperature drifts are a serious issue. Therefore a complex monitoring and compensation mechanism has been developed to minimize these effects. The hardware platform of the XFEL will be based on the new standard μTCA and ATCA. Therefore the timing is implemented as a AMC (Advanced Mezzanine Card) module that fits into both crate systems. A prototype of this new clock and trigger system has been developed and first measurements have shown, that the strong requirements can be fulfilled.

	T. Otake, T. Fukui RIKEN/SPring-8, Hyogo T. Ohata JASRI/SPring-8, Hyogo-ken T. Tanaka RIKEN Spring-8 Harima, Hyogo
	We develop the prototype control system of XFEL/SPring-8　undulator and confirm the capability of the system. The XFEL consists of the 8GeV linear accelerator and the undulators. The undulator is important for lasing of the intense X-ray beam. For the lasing, the required positioning accuracy of the undulator gap is less than 1 micrometer. We have to control the undulator gap to be less than sub-micrometer resolution. To realize, we control the undulators by the periodic feedback with the linear encoders. In this paper, we will describe detail design of the undulator control system on XFEL.

WEP047	Upgrade of Readout System for Beam Position Monitors in the KEKB Beam Transport Line	495
	T. Aoyama, T. Nakamura, K. Yoshii MELCO SC, Tsukuba K. Furukawa, N. Iida, M. Satoh KEK, Ibaraki
	At the KEKB accelerator, electrons and positrons are injected from the LINAC to the storage ring through the beam transport (BT) line. LINAC had continuously injected each beam alternately every about a few minutes. In our linacs system, it is very important to switch acceleration devicesfrom electron mode to position and vica versa to keep high storage currents. To attain this, we have developed new readout system for the beam position monitors (BPMs) at the BT line, by which the fast monitoring is possible. For the old BPM system, it had been taken a few seconds to switch the beam modes and about one second to measure the beam positions. With the new system, measuring interval was achieved to be 20 msec, including switching time, and we demonstrated that new system contributed to stable beam operation. In this manuscript, we will report on a detail of the fast readout for the BT BPM system including its performance.

	This paper presents an implementation of a precision magnet power supply (MPS) for the Pohang Light Source using the digitally controlled pulse width modulation method. The output current of the power supply was ±20 A at the precision of less than 10 ppm. The digital control circuit of the power supply was implemented using the 16-bit ADCs , the TMS320F2808 digital signal processor and the FPGA Spartan3. It has full bridge topology and optimized output filters. The duty ratio for output control was determined using the simple PI method. The one of the Ethernet (including EPICS), CAN or RS232C communication was possible. The various experimental results, such as stability, drift, and controllability, are given to verify the characteristics of the DSP based magnet power supply.

	Modern machines used in high energy physics require sophisticated and complex control systems. The complex systems are usually built as distributed systems. Therefore, the connectivity and communication links between distributed subsystems play a crucial role in the control system. The Advanced Telecommunication Computing Architecture (ATCA) and Advanced Mezzanine Card (AMC) standards have attracted the attention of physics community because they offer various types of Gigabit data communication channels, redundancy high reliability and availability. The standards allow using different types of communication interfaces like PCIe, Gigabit Ethernet, RapidIO. In real-time systems the data transmission latency is also important. The acquisition of real-time data from hundreds of analogue channels is required for the Low Level Radio Frequency Controller (LLRF) controller of XFEL (X-ray Free Electron Laser) accelerator. The paper presents survey of the communication interfaces of the LLRF controller for XFEL. The discussion includes the properties of interfaces provided by ATCA and AMC standards and summarizes requirements for the data links and protocols required by LLRF controller.

WEP051	Acquisition of Analog Signals in ATCA based LLRF Control System for X-FEL	1
	T. Jezynski, M. K. Grecki, W. Koprek, S. Simrock DESY, Hamburg W. Jalmuzna, D. R. Makowski TUL-DMCS, Łódź
	The Low Level Radio Frequency System (LLRF) for the European X-FEL must provide exceptional stability of the accelerating RF field in the accelerating cavities. The regulation requirements of 0.01% and 0.01 degrees in amplitude and phase respectively must be achieved at a frequency of 1.3 GHz while keeping low drifts (during RF pulse). The quality of analog signal processing and distribution plays a crucial role in achieving these goals. The RF signals are connected to the Rear Transition Module (RTM), downconverted there into intermediate frequency (IF) signals and finally sampled at AMC-ADC module. The high quality of the signals (SNR, low crosstalk) must be assured across all the way. The paper presents the results of development of ATCA based LLRF system for XFEL. The special attention is paid to RTM module with downconverters and carrier board conducting analog signals to the AMC-ADC module in the presence of digital processing components (FPGA, DSP).

WEP053	The First Steps of the Beam Intensity Measurement of the Spiral2 Injector	504
	F. Gougnaud, P. Mattei CEA, Gif-sur-Yvette
	The Spiral2 Injector [] includes several diagnostics. The first ones implemented are Faraday Cups, emittancemeters and DCCTs. Two types of acquisition for the beam intensity measurement on the Faraday Cup are being developed. They are based on different industrial electronic boards. The goal of the first type of acquisition is to determine an average intensity value using a traditional acquisition VME board (64 multiplexed channels). This was carried out for the beam tests on the low beam energy line at LPSC Grenoble in May 2009. The second type of acquisition is to perform a measurement synchronized with the beam pulse, the purpose of which is to provide the peak value. Due to the bandwidth of the expected signals, it is necessary to be able to sample at 1 MSamples/second with ADCs of which the resolution is greater or equal to 14 bits. We chose the couple of ADAS IC 10⁸ (4 Megabytes buffer, event and flip/flop modes) and ICV178 (8 analog inputs with high accuracy) COTS VME boards. The associated Epics software is in progress and will also be integrated into the emittancemeters acquisition. [] Preliminary implementations for the new Spiral2 project control system E.

	SOLEIL is a third generation synchrotron. For beamlines acquisition, we have developed a process called "continuous scan". It allows to sample digital or analog events (typically from detectors) with motor positions while motors are moving. The goal is to reduce significantly deadtimes and to improve synchronization between motion and data acquisition. The hardware part based on CPCI architecture with industrial standards CPCI boards ensures perenity and reliability. Low level software is based on master/slave Tango DeviceServers. Such a system can typically run up to 1MS/sec during 30 min (or one hour at lower sampling frequency).This system operates on two SOLEIL beamlines (Cristal and Tempo ones) and in few weeks on a QuickExafs experiment (Samba beamline). An upgrade is under development to scan datas at 1MS/s without limit of time.
WEP056	Motion Controls Using EPICS and Galil Controllers	1
	R. I. Farnsworth ASCo, Clayton, Victoria
	A motion controller standard has been developed, Variant models of Galil motion controller were designed and are in use as the Australian Synchrotron. Controllers designed for small motors have integrated drive electronics, others for bigger motors utilize external drive electronics. An EPICS driver compatible with the range of Galil controllers was developed. The software driver uses the motor record and standard EPICS records to provide the interface. These provide additional features such as master/slave relationships, and gear ratio settings. The Galil driver's unique features include; "position maintenance" algorithms, compatible with Master/Slave relationships, unlike the motorRecord RTRY. Generic interfaces are provided so developers can provide solutions to future needs problems, whilst maintaining a complete EPICS interface to "custom" features. The driver allows swapping between a "primary" and a "secondary" encoder at run time .

	An increase of interest to advanced control techniques and innovative simulation environment applied to cryogenic processes has occurred at CERN, during last decade. As new control algorithm development into real process control system requires significant time, an agile control testing tool externally connected can improve and simplify the procedure of validating advanced controllers implementation. In this context, the present paper describes the development of a control testing tool at CERN, which allows rapid control strategies implementation through the Matlab/Simulink� environment coupled with a large scale cryogenic control system or with the CERN simulation environment. The time delays which are inherently introduced by network link and communication protocol are analyzed and experimentally identified.

	The Large Hadron Collider (LHC) has been commissioned and started operation with beams in 2008, at CERN. Several months of cryogenic operation in nominal conditions have triggered an optimisation of the cryogenic process functional analysis. This lead to a few revisions of the control logic, realised on-the-fly; and to a major rebuild of the logic, implemented during the 2008-9 shut-down. In order to improve the operability, availability and safety of the LHC cryogenics, the process control structure was reorganised; the logic of process phases, interlocks, regulators and templates for automatic code generators were modified; the hard-wired vacuum-quality signals were upgraded to provide more detailed information; the protection of current feed boxes was enhanced by the addition of new signals; a new tool for remote-reset of Profibus-IO was developed. The databases, containing all instruments and controls information, were rationalized; the automatic specification generators, which extract the parameters used in the control software, were simplified. This paper describes the main improvements applied during the 2008-09 shut-down, and suggests perspectives of further developments.

	Consorzio RFX will host two experimental devices to address the main issues of the ITER Heating Neutral Beam Injectors (HNBIs): SPIDER (Source for the Production of Ions of Deuterium Extracted from Rf plasma), an ion source at low extraction voltage (100 kV), and MITICA (Megavolt ITer Injector and Concept Advancement), a HNBI at 1 MV. ICE (Insulation and Cooling Experiment) is a test facility developed at Consorzio RFX to tackle significant SPIDER and MITICA technological aspects that require a preliminary study. The ICE control system is mainly based on commercial off-the-shelf products. It is composed of three tiers: automation, supervision and data logging. The automation tier is based on Siemens PLC technology. The supervision tier relies on the commercial PVSS SCADA system that is widely used at CERN. The data logging tier, the only part of the ICE control system not based on industrial products, extends the functionalities of MDSplus, a framework for the management of scientific data. This paper analyses the ICE control system, describing the three tiers and explaining the reasons for the choices. A preliminary description of the ICE control modes is supplied too.

	Single section technological LU-10 electron linac * is located in National Scientific Center "Kharkov Institute of Physics and Technology". The linac has got the following specifications: beam output energy 10 MeV, pulse current up to 1A, pulse width up to 4 mcs, repetition rate 300 Hz. Average beam power is up to 10 kW. The accelerator is dedicated for electron-beam sterilization. Beam forming line consists of four magnetic lenses and four steering coils. The article describes the upgrade of the power supply system for electromagnetic optic elements of the LU-10 accelerator. Power suppliers of magnet optic elements have been replaced at the beginning of the 2009. Programmable power supplies equipped with intellectual controllers with CANopen interface took the place of the old ones. The power suppliers ensure current drive in the coils of magnet elements with 0,05% stability. The suppliers control continuously load characteristics (checking both voltage and current) and initiate beam off signal when load changes due to coil-winding short circuit or other reasons. Structure of the power supply control system software is described as well as results of the system tests. * K. I. Antipov, M. I. Ayzatsky, Yu. I. Akchurin et al.

	D. R. Monnier-Bourdin GreenField Technology, Breuillet T. F. Debelle, M. M. Ravindran National Instruments, Austin
	Accurate timing is a key aspect of large physics experiments. More and more, Commercial-Off-The Shelf (COTS) technologies are used to provide synchronization down to a few picoseconds. This approach allows a wide selection of equipment, offers a high level of flexibility, and guarantees a smooth evolution as new technologies become available. For example, Greenfield Technology proposes a picosecond timing system that provides several hundred triggers to equipments distributed over an area of thousands of square meters within a resolution of 1 ps and low jitter < 15 ps. This system is built around a central oscillator transmitter which delivers a serial data stream over an optical network to manage delay generator triggering and time base. By combining this distributed timing system and the clock and triggering synchronization features of the PXI backplane, high speed instruments, such as digitizers, can also be synchronized with picoseconds accuracy to guarantee the best measurement quality. Due to the fact that all of these timing features are built into the backplane of the PXI chassis, the need for cumbersome cabling is drastically reduced.

	To reduce the beam losses when preparing high intensity proton beam for the CERN Neutrino to Gran Sasso (CNGS) facility, a new Multi-Turn extraction (MTE) scheme has been implemented in the PS, to replace the present Continuous Transfer (CT) to the SPS. Prior to extraction the beam is separated in phase space into a central core and four islands by means of non-linear magnetic elements. Each beamlet is then ejected from the PS using fast kickers and a magnetic septum. Industrial off-the-shelf components have been used for the low-level part of the MTE kicker control system. National Instruments PXI systems are used to control the high voltage pulse generators and a SIEMENS programmable logic controller (PLC) handles the centralised oil cooling and gas insulation sub-systems. The different types of low-level controllers are linked via Ethernet to a VME Front-End Computer (FEC) which serves as interface to the higher layers of the accelerator control system. The publication of the various equipment functions to the application layer is performed through generic object oriented classes developed with the CERN Front-End Software Architecture (FESA), deployed at the FEC level.

	Funding: We want to thank the Land Nordrhein-Westfalen and the Forschungszentrum Jülich, Germany, for their ongoing financial support. The soft X-ray Beamlines at the synchrotron radiation source DELTA, located at the Technische Universität of Dortmund, Germany, are operated under EPICS. Some of the components and software of the soft X-ray beamline control system were developed in cooporation with the company ENZ in Berlin, Germany. A compact stepper motor driver unit for typically 8 axis with a small embedded LINUX-PC is now in routine operation at DELTA and at the Soft X-Ray Beamline at the Australian Synchroton near Melbourne. The same PC-system with modified software is used for readout of a current amplifier (LoCuM, build by the company ENZ). This setup is typically used for several photodiodes or a photon beam position monitor of the beamlines. The photon beam position monitoring is done in routine operation at all beamlines at DELTA with this system, allowing an easy and fast data exchange between accelerator and beamlines. During the last years a continous improvement and optimization of the systems has been done at DELTA to allow a routine operation of the soft X-ray beamlines and an easy maintenance of the system.

	We have developed a controller for the beam monitor system of XFEL/SPring-8. The control items are the electronics of a beam position monitor (BPM) and a current transformer (CT), the actuator of a screen monitor (SCM) and the stepper motors of a SCM lens system and a beam collimator. To operate such complicated devices, we designed a control system based on a programmable logic controller (PLC). The PLC enables us to implement complex commands easily. For the communication between the PLC and other equipments, we employed FL-net (a protocol to communicate with computers) and DeviceNet (a connection with peripheral devices). Since FL-net is strongly supported by MADOCA, the official framework of SPring-8, we can easily integrate the PLC into the upper level system. DeviceNet is used in the electronics of the BPM and the CT and in the motor controllers of the SCM and the collimator. We newly developed a DeviceNet-based motor controller to satisfy our complicated requirements. Another multi-wire cable is equipped to manipulate the SCM actuator and so on. We tested the beam monitor controller at the SCSS test accelerator and confirmed that it worked well.

	Beam loss monitors are essential diagnostic devices for the operation of J-PARC Main Ring, which aims at the acceleration of the world-highest-power proton beams. The data acquisition system of the beam loss monitors is required to measure the time structure of the output signal integrated during the acceleration cycle. The repetition rate of the measurement in the duration needs to reach at a level of tens of Hertz with time jitters less than a few milliseconds. In addition, the measured data must be accessible by the EPICS-based control system, which manages the whole accelerator control. In order to satisfy the requirement, a new type of Input / Output Controller (IOC), which runs Linux on a CPU module of FA-M3 Programmable Logic Controller (PLC), has been adopted. To execute the data acquisition, the CPU module functions with high speed data acquisition modules of FA-M3 on the PLC-bus. We found that the IOC could meet the requirements and the development and maintenance of the software for the IOC was considerably efficient.
WEP071	Three Frequency Undulator Radiation FEL Gain of Betatron Oscillations and Beam Energy Spread	1
	V. Gupta KCB Technical Academy, Indore G. Mishra Devi Ahilya University, Indore
	A new three frequency undulator has been proposed[1].The authors assume that the electron moves on axis in a three harmonic undulator structure. Let us consider the case of the fundamental. The intensity at this frequency will be further enhanced by the contribution from the modulation at sum-difference frequencies . For the next odd harmonics of the fundamental, there will be contributions from the harmonic field components to produce an enhanced intensity at the third odd harmonics. At this frequency there will be further contributions from the sum-frequency. However the intensity contributions from the sum-difference frequency will be small in comparison to the primary odd harmonics and the net result is that the third harmonic intensity will be raised . Thus the three frequency works in a similar way to that of the harmonic undulator scheme. In this paper we calculate the three frequency undulator radiation and discuss the feasibility of free electron laser operation with this undulator scheme and also special attention to enhance gain in the presence of the betatron oscillations in the system. 1.

	C. Y. Wu, J. Chen, K. T. Hsu, S. Y. Hsu, K. H. Hu, D. Lee NSRRC, Hsinchu
	In order to redesign and improve performance of EPU 4.6 for the Taiwan Light Source (TLS), implement new control system and develop application programs of EPU 4.6 are under way. The EPU 4.6 driver system includes 8 axes servo motors with Sin/Cos absolute encoder and 8 SSI absolute encoders for precision position control. Due to proprietary design of the vendor and lack of needed technical documents of the existed motor drivers and motor controllers, obsolete these devices and replaced by another open solution is the most difficult decision. A VME crate installs CPU board, DI, DO, AI and AO card, SSI read-only interface is used as EPU 4.6 controller. The motion controllers are connected to the VME CPU via Ethernet directly. The power supplies of correction coil are MCOR30 system manufactured by BiRa Systems. The simple PLC dedicated for interlock protection purpose which take input from limit switches, kill switches, tilt sensors and emergency button from the driver system. The interlock logic will restrict motion if any limit sensor is activated before removed and interlock reset. Features and benefits of the new control system of EPU 4.6 will be summary in this report.

WEP073	Control System Integration of the PETRA III BPM System based on Libera Brilliance	543
	H. Wu, P. K. Bartkiewicz, I. Krouptchenkov, G. Kube, F. Schmidt-Foehre, F. Wedstein, J. Wilgen DESY, Hamburg
	The PETRA III Storage Ring has recently successfully commissioned the new BPM System based on ~230 Libera Brilliance [1] modules. This is at present the largest full installation of these modules. This paper presents the complete BPM system from the control aspect. The distributed Libera Brilliance modules are connected via the control system internet. A dedicated middle-layer Linux PC running in a multithreaded environment communicates with all modules using the CSPI package provided by the vendor of the Libera Brilliance modules. This middle layer processes runs in the framework of the TINE control system and services requests from the user applications. In this case, the middle layer server is heavily multithreaded and deals with hundreds of Brilliance modules and is therefore unique, as all the other Libera installations run in a one-process-to-one-Libera mode. An automation procedure has also been developed for remote installing and updating software packages, as well as restarting and rebooting the CSPI server running on the Libera modules.

WEP074	Upgrading the Control System of the Movable Masks for KEKB	546
	T. Nakamura MELCO SC, Tsukuba K. Furukawa, T. T. Nakamura, J.-I. Odagiri KEK, Ibaraki
	The positron ring and the electron ring of KEKB have their own dedicated movable masks to cut off spent electrons/positrons near the beam orbit to reduce background in the detector. The stepping motor drivers of the movable masks were controlled by a Programable Logic Controller (PLC), which was supervised by a VME-based IOC. The IOC and the PLC was connected with each other by using GP-IB interface for the communication. Recently, however, the GP-IB connection came to be unstable causing communication errors between the IOC and the PLC. In order to solve the problem, a new type of IOC, which runs Linux on a CPU module of FA-M3 PLC, has been adopted. The CPU functions with standard I/O modules of FA-M3 on the PLC-bus. In this control system, we replaced an existing ladder CPU with the IOC and the ladder program with an EPICS sequencer program for the efficiency of software development and ease of maintenance. The new IOC has been successfully serving since it was put in operation in September 2008. In this paper, we describe the details of the new control system and its experiences up to the date.

	The J-PARC Main Ring supplies high energy proton beams to the hadron experiment facility through the slow extraction line. It comprised of a series of septa, staring from a pair of electrostatic septa (ESS) followed by magnetic septa, and some of those septa are movable by using stepping motors to adjust their positions for a better optics. In order to control the power supplies of the septa and the stepping motors, an EPICS-based control is implemented based on a new type of Input / Output Controller (IOC), which runs Linux on a CPU module of FA-M3 Programmable Logic Controller (PLC). The CPU functions with normal I/O modules of FA-M3 on the PLC-bus. The most remarkable feature of the control system is that we replaced ladder programs with EPICS sequencer programs for the efficiency of the software development and ease of maintenance. And we found that the new type of IOCs had worked without any serious troubles during the beam commissioning period, from Run#21(Jan.2009) through Run22(Feb.2009). This paper describes the details of the new IOC and its experiences in J-PARC operation including long term stability.

	L. S. Jirden, A. Augustinus, M. Boccioli, P. Ch. Chochula, L. Wallet CERN, Geneva
	The ALICE experiment, devoted to heavy ion collision studies, is one of the four large detectors of the 27 km Large Hadron Collider (LHC) at CERN. The experiment saw the first circulating beams in September 2008 and is preparing for the first collisions in autumn 2009. The ALICE experiment is composed of 18 sub-detectors, each with up to 15 different sub-systems, such as high voltage, front-end electronics, that need to be controlled with a high level of reliability. The development of a coherent control system for all the various sub-systems and a large variety of devices is a major challenge. In order to assure safe operation of the experiment, each device needs to be configured, controlled, and monitored and all the data involved must be properly refreshed, monitored and stored. The device control is mainly based on OPC, and PVSS SCADA systems customized by CERN. This paper describes the device control architecture, and how it ensures safe and coherent operation using the OPC server / client technology. It also discusses the impact of the communication performance for large-scale control systems dealing with large amounts of data and how this has been optimized.

	In the accelerator field, the utility system, including cooling water, cooling air, electric power etc. must proceed the reliable and stable control. These systems almost cover all locations of accelerator instrument and require integrating all the hybrid control systems. A novel data exchange mechanism via Ethernet or wireless Ethernet is developed to provide the distributed PCs, PLCs(Programmable Logical Controller), PACs(Programmable Automation Controller) and embedded devices with reliable communication. The system also introduces a platform with real-time status to view, control, analyze and alert. The users can access online and offline data by adequate viewers.

WEP081	A Programmable Logic Controller-Based System for the Recirculation of Liquid C6 F14 in the ALICE High Momentum Particle Identification Detector at the Large Hadron Collider	1
	I. Sgura, A. Franco, C. Pastore INFN-Bari, Bari G. De Cataldo, P. Martinengo CERN, Geneva C. Dell'Olio, U. Fratino Università e Politecnico di Bari, Bari
	We present the design and the implementation of the Control System (CS) for the recirculation of liquid C6F14 in the HMPID. The HMPID is a sub-detector of the ALICE experiment at the CERN-LHC and uses C6F14 as Cherenkov radiator medium in twenty-one quartz trays for the measurement of the velocity of charged particles. The primary task of the Liquid Circulation System(LCS)is to ensure the highest transparency of C6F14 to ultraviolet light. In order to provide safe long term operation a PLC-based CS has been implemented. The CS supports both automatic and manual operating modes,remotely or locally. The adopted Finite State Machine approach minimizes the possible operator errors and provides a hierarchical control structure allowing the operation and monitoring of a single radiator tray. The LCS is protected against anomalous working conditions by both active and passive systems. The active ones are ensured via the control software running in the PLC whereas the human interface and data archiving are provided via PVSS, the SCADA framework which integrates the full detector control. The LCS has been fully commissioned over the last two years and proved to meet all requirements.
WEP082	Embedded EPICS Controller for KEKB Pulsed Quadrupole Magnet Power Supply	558
	K. Mikawa, K. Furukawa, T. Mimashi, J.-I. Odagiri KEK, Ibaraki T. Nakamura MELCO SC, Tsukuba
	The pulsed quadrupole magnets have been installed in KEKB for the betatron tune adjustment. These magnets need to be controlled by the existing EPICS-based control system of the KEKB accelerator. While the control logic required for the operation of the magnet power supplies is rather conventional, it is preferable that we choose a front-end controller which allows us to develop and maintain the software in a highly efficient manner to cope with limited human resources. In order to satisfy this requirement, a new type of Input / Output Controller (IOC), which runs Linux on a CPU module of FA-M3 Programmable Logic Controller (PLC), has been adopted. The CPU functions with normal I/O modules of FA-M3 on the PLC-bus. We found that replacing ladder programs with EPICS sequencer makes the development and maintenance of the software for the IOC considerably efficient. This paper describes the details of the new IOC and its experiences in KEKB operation including long term stability.

	Funding: Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U. S. Department of Energy Brookhaven National Laboratory's Relativistic Heavy Ion Collider (RHIC) uses many commercially available instruments - for example spectrum analyzers, oscilloscopes, digital volt meters, signal generators - as integral parts of instrumentation and control systems. Typically these systems are remotely controlled. Using commercial instruments has many benefits. Manufactures have the skill, knowledge, and experience to produce high quality products. The price performance ratio is hard to duplicate. There are also disadvantages. Proprietary interfaces, single platform drivers, and reliable operation provide challenges for implementation and unattended operation. Several of the systems used at RHIC will be described. Their issues and solutions will be presented.

	M. Acar, E. Blanco, D. Martin-Gomez, J. P. Palluel CERN, Geneva
	The low beta quadrupole magnets in the CERN Large Hadron Collider (LHC) accelerator are installed in high radiation areas next to the experiments. A fully remote positioning control system based on motorized jacks has been implemented to align the magnets in real time. The system is also equipped with sophisticated survey sensors based mainly on hydrostatic leveling and stretched-wire position systems. Dedicated monitoring and control applications have been developed to allow the LHC operation team to supervise this complex system from the CERN Control Center. This paper gives an overview of the present controls architecture and describes the new operational tools developed to assist the beam operation.

WEP086	EPICS IOC of WindowsXP-based Oscilloscope for Fast BPM Data Acquisition System	567
	M. Satoh, K. Furukawa, T. Suwada KEK, Ibaraki T. Kudou, S. Kusano MELCO SC, Tsukuba
	In the KEK Linac, about 100 monitors (BPMs) are used for the beam orbit measurement. The previous data acquisition (DAQ) system consists of the VME and the digital oscilloscope. The maximum DAQ rate is about 1 Hz which is limited by an oscilloscope performance. We have developed the new DAQ system since we have an ongoing linac upgrade project aiming a fast beam-mode switch, in which the fast beam position measurement is strongly required up to 50 Hz. The new BPM DAQ system is a WindowsXP-based fast digital oscilloscope. The DAQ software has been initially developed by C++ and TekVISA. It acquires the waveform signal from the BPM electrodes and calculates the beam positions. It is very useful to run the DAQ software as an EPICS IOC since the most part of Linac parameters are accessible via EPICS protocol and they are archived by EPICS archiver. Recently, we developed the BPM DAQ software based on EPICS which can make the oscilloscope work as an EPICS IOC. The results of performance test show that the new DAQ software can work well up to 50 Hz. In this paper, we will describe the fast BPM DAQ software based on EPICS and the results of its performance evaluation in detail.

	D. Schmied, E. Burtin, J. M.C. Chaize, M. Hahn, I. Parat, M. Peru, P. V. Verdier ESRF, Grenoble
	The ESRF is in operation since many years. Due to the aging vacuum system, but also driven by the development to increase the machine performances and the continuous upgrade of our vacuum installations we have been reviewing our philosophy of data acquisition and monitoring, while using new technologies and taking into account our gained operational experience. This helped us to anticipate machine failures such as leaks, overheating of RF-liners or poor chamber alignments and therefore reduce machine down times. This paper outlines our work on the development of a new vacuum user interface, which not simply reflects the actual status of our vacuum system, but which provides a dynamic survey of computed vacuum signals highlighting unusual vacuum behaviors and making their identification and location easier from an operator point of view. It also presents the use of Pb-shielded PLC units in the storage ring and their integration towards a dynamic remote control system.

	F. Ravotti, I. Atanassov, F. Lucas Rodriguez, J. Morant, P. Palazzi CERN, Geneva
	The TOTEM detectors together with their front-end electronics are located in LHC areas where high radiation levels are expected. To understand the radiation-induced changes on the detector performances and to survey anomalous increases of radiation levels, the Ionizing Dose and the Particle Fluence are monitored during TOTEM operation. This set of information is made available on-line through the TOTEM DCS. The basic unit of the radiation monitoring system is an integrated sensor that hosts 4 types of monitors (RadFETs & p-i-n diodes) connected to the electronics via readout cables. In total, 36 sensors are installed in TOTEM. The one located in the Roman Pots, along the LHC tunnel, sit more than 300m far from the readout electronics. This characteristic makes this system unique with respect to the one implemented for the other LHC experiments. In this article we detail the design of this part of the TOTEM control system based on ELMBs, together with the PVSS control SW architecture and its integration at the supervisory level of the TOTEM DCS. Results of a series of commissioning tests performed at the LHC will be also presented in order to evaluate the performance of the system.

	Y.-M. Abiven, J. Coquet, X. Deletoille, F. Dohou, P. Monteiro, R. P. Patrick SOLEIL, Gif-sur-Yvette
	SOLEIL is a third generation Synchrotron radiation source located in France near Paris, having the classical accelerator structure consisting of a Linac pre-accelerator, a Booster accelerator and a Storage Ring, which are connected by two transfer lines. Since 2006, the Storage Ring delivers photon beam to beamlines. In order to protect the very sensitive and essential equipment during machine operation, (vacuum chambers, vacuum valves, mirrors, etc.) an interlock system has been implemented. This system is based on industrial and autonomous PLC (Programmable Logic Controller). Interlock system and subsystems are based on Siemens PLCs S7-300 family products, which are standard hardware components of SOLEIL Control Systems. Surrounding the booster and the 354 meters of the storage ring, 87 PLCs configurations are installed with 50 for vacuum security, 19 for diagnostics subsystem security and 18 for the interlock system. PLC cycle time ensures a signal between detection and RF interlock generation around 30 and 50 ms.

	S. K. Thakur, A. De, Y. Kumar, S. Saha, T. P. Tiwari DAE/VECC, Calcutta
	RF system of K-500 superconducting cyclotron at VECC is a complex three phase system operating in the frequency range of 9-27 MHz with potential of around 90kV feeding to each of three RF-cavities placed in median plane of cyclotron at 120° apart. At final stage in each phase, a water cooled vacuum Tetrode Tube EIMAC 4CW150000E is used as high power amplifier, capable of delivering 80 kW RF power to RF-cavity. A high voltage DC power supply rated at 450 kW at 20kV feeding to their Anodes, is developed in-house with ultra-fast(5 μ-sec)Crowbar protection system to protect the tubes against Internal Arc using energy diverter topology. High power vacuum tubes are prone to internal Arc and can get severely damaged if excessive energy is dissipated during fault. A highly specialized scheme that incorporates a complex electronics control and fault processing circuitry which does latching for fault diagnostic and replicates the hardwired logic circuit to generate a trigger pulse to fire Ignitron as crowbar switch ignoring the noise as well as providing redundancy to trip Mains ACB. Circuit simulations and test results with specialized measurement procedure are described in this paper.

	The accelerator safety interlock system to protect persons from radiation hazard induced by electron beams and synchrotron radiation has been operating over a decade in SPring-8. This system is monitoring the safety condition of accelerator components and stops injection electron beams in case of the failure, and stored electron beams are aborted if necessary. SPring-8 complex is composed of five accelerator/beam-transport areas. The injection beam direction can be frequently changed between the two accelerator areas; SPring-8 storage ring and NewSUBARU storage ring. Therefore, the safety interlock system was built introducing the idea of the "operation mode" control system. Once one of the operation modes is selected, the electron beams transport route is defined uniquely. The operation mode control system manages the combination of some accelerator/beam-transport areas. Since the operation mode control system became complicated because the number of "operation mode" has increased according to SPring-8 upgrades, we are planning to construct new safety interlock system. We will report the status of the current safety interlock system and the conceptual design of the new one.

WEP092	New Beam Loss Monitor for 12 GeV Upgrade	582
	J. Yan, K. L. Mahoney JLAB, Newport News, Virginia
	Funding: Authored by Jefferson Science Associates, LLC under U. S. DOE Contract No. DE-AC05-06OR23177 This paper describes a new VME based machine protection Beam Loss Monitor(BLM) signal processing board designed at Jefferson Lab which features high sensitivity, high resolution, and low cost per channel. Photomultiplier based BLMs are used to detect bremsstrahlung from low level beam loss during tune-up and beam operations and to provide a machine protection trip before the beam can damage accelerator components. Typically, the two functions are incompatible as the display of instantaneous low level loss requires a fast low noise, wide dynamic range signal processor while machine protection requires some form of high level integrating signal processor. The new 8-channel BLM card has linear, logarithmic, and integrating amplifiers that simultaneously provide the optimal signal processing for each application. Amplified signals are digitized and then further processed through a FPGA. Combining both the diagnostic and machine protection functions in each channel allows the operator to tune-up and monitor beam operations. Other features include extensive built-in-self-test, fast shutdown interface(FSD), and 16-Mbit buffers for beam loss transient play-back.

	Funding: SLAC/DOE Contract DE-AC02-76-SF00515 A state-of-the-art Machine Protection System for the SLAC Linac Coherent Light Source has been designed and built to shut off the beam within one pulse during 120 Hz operation to protect the facility from damage due to beam losses. Inputs from beam loss monitors, BPMs, toroids and position switches of insertable beam line devices are connected to a number of Link Node chassis placed along the beam line. Link Nodes are connected with a central Link Processor in a star topology on a dedicated gigabit Ethernet fiber network. The Link Processor, a Motorola MVME 6100, processes fault data at 360 Hz. After processing, rate limit commands are sent to mitigation devices at the injector and just upstream of the entrance of the sensitive undulator beam line. The beam's repetition rate is lowered according to the fault severity. The SLAC designed Link Nodes support up to 96 digital inputs and 8 digital outputs each. Analog signals are handled via standard IndustryPack (IP) cards placed on the Link Node motherboards with optional transition boards for signal conditioning. A database driven algorithm running on the Link Processor provides runtime loadable and swappable machine protection logic.

	SPES (Selective Production of Exotic Species)is a new INFN facility whose construction is planned for the years 2009-2014. It aims to provide the nuclear physics community with neutron rich nuclei beams produced by impinging an UC target by a proton beam delivered by a commercial cyclotron. Security requirements constitute the most critical issue in the control system design. High reliability PLCs will be extensively used in all applications that affect the personnel and machine safety; redundant configurations will be implemented where appropriate. EPICS has been chosen as general framework for the development of SPES controls: therefore the integration of PLCs in an EPICS network is another key point in the control system design. We present the technical solutions foreseen to comply with SPES safety requirements and discuss the possible approaches to integrate PLCs in the EPICS environment.

	The X-ray Free Electron Laser (XFEL) Facility in SPring-8 is now under construction. The accelerator safety interlock system for the XFEL is required for protecting persons from radiation hazard. The system consists of three interlock systems; a central interlock system (CIS), an emergency interlock system (EIS) and a beam-route interlock system (BIS). The CIS monitors the safety equipment status. The EIS monitors status of emergency stop buttons. The BIS monitors consistency between the predefined electron beam route to the downstream insertion devices and the actual transport route by inputting the current of the bending magnet at the beam switching points. If the condition is unsafe, these systems don't give the permission to the accelerator operation and stops the electron beam. The programmable logic controller (PLC) is basically used to control of each interlock system. It is required to stop the electron beam within 16.6ms because the design maximum repetition frequency of the electron beams is 60Hz. Therefore, we developed the optical module that can transmit high-speed stop signals. We report the present status of accelerator safety interlock system for the XFEL.

	The operation of the Tore Supra tokamak requires the orchestration of more than 50 systems including several sub-plants (cryogenic plant, magnetic coils, water cooling loops, multi megawatt heating systems, etc.), as well as plasma diagnostics. To ensure both plasma performance and safe operation, it is crucial to optimise the way each plasma discharge is driven. The Tore Supra real time control system (RTCS) has been developed on that purpose. Default detections is performed at both sub-plant systems and inter-plant links levels using hardware and software means. Additionally, a dedicated unit is devoted to the supervision of the overall plasma discharge by collecting the sub-plant status and the plasma parameters from diagnostics. Any abnormal event or discrepancy with respect to reference parameters is detected and classified as machine protection event (e.g. electrical arcing on RF antenna or too high impurity level, etc.), or as plasma performance discrepancy event (e.g. degraded confinement regime). Then a pre-defined recovery strategy is applied (e.g. balance load distribution between sub-plants). Several examples of detection and recovery strategies will be reported.

WEP099	Management of Critical Machine Settings for Accelerators at CERN	594
	W. Sliwinski, P. Charrue, V. Kain, G. Kruk CERN, Geneva
	In high energy accelerators as LHC energy stored in the beams is orders of magnitude above the damage level of accelerator components like magnets. Uncontrolled release of energy can lead to a serious damage of equipment and long machine downtimes. In order to cope with these potential risks Protection Systems were developed at CERN including two software systems: MCS (Management of Critical Settings) and RBAC (Role Based Access Control). RBAC provides means for authentication and an authorization facility which grants access to the critical parts of a control system. Second layer of security is provided by MCS by ensuring that critical parameters are coherent within the software and hardware components of a control system and can only be changed by an authorized person. MCS system is aimed for the most critical and potentially dangerous equipment (e.g. Beam Loss Monitors) and is complementary to RBAC infrastructure. Both systems are fully integrated in the control system for LHC and SPS and were successfully commissioned for the first beam in LHC. This presentation will describe the MCS architecture, current status and its operational deployment together with plans for the future.
WEP100	The SSRF Radiation Safety Interlock System and its Applications	1
	X. J. Xu, J. H. Cai, K. M. Fang, C. Jun, X. Liu, J. H. Wang, X. Xia, J. Q. Xu SINAP, Shanghai
	Radiation Safety Interlock System (RSIS) for the Shanghai Synchrotron Radiation Facility (SSRF) has been built and operated more than one year, it is composed of two subsystems, the Access Control System (ACS) and the Radiation Containment System (RCS).The ACS prevents personnel from being exposed to the extremely high radiation inside the SSRF shielding tunnel during machine operation. The RCS prevents personnel from being exposed to the high radiation outside a shielding tunnel during either normal or abnormal operation. The implementation of the ACS is based on the Programmable Logic Controllers, key transfer interlocking systems and ID Card System. The RSIS is based on fail-safe, redundancy, multiplicity. Any violation of the RSIS will result in the inhibiting of redundant permission to the associated interlock systems, and cease the injection process and eliminate the entire stored electron beam in the SSRF. This paper describes the system design, the logic, and some experience of using RSIS systems at SSRF.
WEP101	Integrated Access Control for PVSS-based SCADA Systems at CERN	597
	P. Golonka, M. Gonzalez-Berges CERN, Geneva
	The protection of the PVSS-based Human-Machine-Interface parts of the Control Systems for the LHC accelerator and the experiments at CERN is implemented using the JCOP Framework Access Control component. It allows to protect from non-malicious activity (such as misuse due to operator's mistake) by enabling/disabling the elements of the User Interface. It extends the native PVSS mechanisms for user-authentication and makes the management of the role-based authorizations easy to configure and maintain. Ultimately, it enables the synchronization of the access-control related data across distributed systems, and allows to synchronize this data with central user-management resources at CERN (such as Active Directory), and automated creation of user accounts.

	This paper describes the LHC Access System, built to protect the personnel working in the LHC from radiation hazards; the system's architecture and the experience gathered of commissioning, testing and using it. This system is made of two parts: the LHC Access Control System (LACS) and the LHC Access Safety System (LASS). Using redundant, fail-safe PLC's and a supplementary cabled loop the LASS guarantees the safety of the personnel in all events. Using industrial components, the LACS regulates the access to the tunnels and experimental areas by identifying users and checking their authorizations. It allows a remote or automatic operation of the access control equipment and restricts the number of users working simultaneously in the interlocked areas. Since the beginning of the operational phase, additional efforts and studies have been done to ensure the inviolability of this protection system by users not holding the required credentials. The design, procurement and installation of the entire system took more than 4 years and the commissioning phase lasted about 12 months. The paper presents as well the return of experience of the first 2 years of operation.

WEP103	Introduction of Radiation Monitor System for the Shanghai Synchrotron Radiation Facility	1
	X. Liu, X. Xia SINAP, Shanghai
	Shanghai Synchrotron Radiation Facility (SSRF) is the first third-generation synchrotron radiation facility in China and it will be completed and put into use in April 2009. Radiation Monitoring System in SSRF is an important part of radiation safety system. This paper describes the Radiation Monitoring System in real time and its performance during beam commissioning. This system consists of sets of neutron and gamma monitors and data acquisition and computer system mounted in central control room. The types and features of the monitors and the functions of the computer system based on EPICS, SAD, PYTHON and MYSQL are given in detail. The performance of the system during the commissioning showed that the system performs as design expected, and can successfully prevent people from being exposed to abnormal radiation level.
WEP105	Beam Containment System for NSLS-II	1
	S. L. Kramer, W. R. Casey, P. K. Job BNL, Upton, Long Island, New York
	*Funding: Work supported by U. S. DOE, Contract No. DE-AC02-98CH10886 The shielding design for the NSLS-II will provide adequate protection for the full injected beam loss in two periods of the ring around the injection point, but the remainder of the ring is shielded for lower losses of <10% full beam loss. This will require a system to insure that beam losses don't exceed these levels for a period of time that could cause levels outside the shield walls. This beam containment system will measure, provide a level of control and alarm indication of the beam power losses along the beam path from the source (e-gun, linac) thru the injection system and the storage ring. This system will consist of collimators that will provide limits to (an potentially measure) the beam miss-steering and control the loss points of the charge and monitors that will measure the average beam current losses along the beam path and alarm when this beam power loss exceeds the level set by the shielding specifications. This will require some new ideas in beam loss detection capability and collimation. The initial planning and R&D program will be presented. skramer@bnl.gov**
WEP106	Configuration Management Plan for Interlock Safety Systems at the Linac Coherent Light Source (LCLS)	1
	M. E. Saleski, E. Carrone SLAC, Menlo Park, California
	Safety critical systems require more than good design in order to provide adequate safety assurance: the configuration must be controlled so that system operation is not compromised and coherent maintenance is guaranteed; new designs and design changes must be thoroughly examined and rigorously reviewed to ensure the system operates as intended; routine system testing must be performed to ensure system's resiliency and to reveal covert un-safe failures; documentation, plans, guidelines and procedures must be properly managed to ensure appropriate implementation, testing, and troubleshooting. This paper shows how a Quality Assurance (QA) Program which incorporates elements of IEC61508, ANSI/ISA 84.01, and ISO9001 standards has been implemented in the SLAC National Accelerator Laboratory to design and operate Safety Interlock Systems for the LCLS facility. The aim is to create a tailored QA program that satisfies the above mentioned requisites, as well as the Department of Energy's 'Integrated Safety Management System' requirements.
WEP107	Linac Coherent Light Source Personnel Protection System Architecture	1
	P. A. Bong, E. Carrone SLAC, Menlo Park, California
	Programmable systems are becoming the de facto standard for Safety Interlock Systems, allowing for increasing complexity of personnel protection. The SLAC National Accelerator Laboratory has implemented a programmable safety interlock system utilizing a graded approach to protect personnel from exposure to prompt radiation. The Personnel Protection System architecture is based on two tiers of programmable systems performing access control and safety interlocks. The strategy consists in isolating the safety functions from the access control and system monitoring performed through EPICS. The isolation allows the safety functions to be guaranteed even in the absence of a fully working control system. The safety functions are performed by redundant Programmable Logic Controllers certified for safety applications. Each PLCs was programmed by an independent engineer to provide some level of diversity and defense from coding errors. Functional testing was performed through a test bench and, after deployment, through a field checkout procedure designed to certify the system for operation. New processes were developed to manage the life cycle and the integration with existing installations.

WEP108	Contribution of the CLS Control System to the CLS Accelerator System Reliability	603
	E. Matias, H. Zhang, M. S. de Jong CLS, Saskatoon, Saskatchewan
	The control system software plays an increasingly important role in achieving overall accelerator system reliability, in this regard the CLS control system is no different. This paper reviews the two aspects of control system reliability (1) the reliability of the control system itself and it contribution to system reliability and (2) the use of the control system as a tool to aid in predicting and localizing system failure therefore providing an indirect impact on mean-time-between-failure and mean-time-to-repair. The paper provides a survey of metrics used at the CLS to evaluate system reliability, several failure modes that have been localized and removed from the system design to contribute to overall reliability. Recently CLS has deployed a new approach to alarm annunciation and fault location based on voice annunciation and nested dashboard display screens.
WEP109	Alarm Rationalization: Practical Experience Rationalizing Alarm Configuration for an Accelerator Subsystem	606
	X. Geng, S. M. Hartman, K.-U. Kasemir ORNL, Oak Ridge, Tennessee
	Funding: Work supported by Oak Ridge National Laboratory for UT-Battelle, LLC, under contract DE-AC05-00OR22725 for the U. S. Department of Energy. A new alarm system toolkit has been implemented at SNS. The toolkit handles the Central Control Room (CCR) 'annunciator', or audio alarms. For the new alarm system to be effective, the alarms must be meaningful and properly configured. Along with the implementation of the new alarm toolkit, a thorough documentation and rationalization of the alarm configuration is taking place. Requirements and maintenance of a robust alarm configuration have been gathered from system and operations experts. In this paper we present our practical experience with the vacuum system alarm handling configuration of the alarm toolkit.

WEP110	Standards Based Measurable Security for Embedded Devices	609
	B. Copy CERN, Geneva
	Funding: CERN - EN Department Control systems are now routinely connected with enterprise networks and even wide area networks, opening their components to a large array of cyber security threats. Facing threats on such a large scale can now longer solely be done through ad-hoc incident response and post-mortem activities. Defense in depth strategies are being widely adopted and advocated through emerging control systems specific cyber security standards [1]. With these strategies comes the need to accurately prioritise risks and manage system assets, in order to implement measured, tailored security restrictions and automatically assess damages to provide efficient and precise incident response. Eventually, an organization must be able to measure incidents trends and evaluate business impact to feed constant security policy reviews. CERN has implemented a control device cyber security test bench, entitled TOCSSiC [2], updated to provide standards-compliant measurements. Such measurements can be employed to automatically evaluate device vulnerabilities and security policy compliance. [1] F.
