 Evolution of Control Systems for Large Telescopes and Accelerators : A retrospective  
 
  • Y.S. Mayya
    BARC, Mumbai, India
  
  Particle accelerators and telescopes are big instruments of experimental physics. Even though markedly different in design & construction, particle accelerators and telescopes complement each other in answering man's most profound questions on the nature and origin of universe. Today's particle accelerators are mammoth microscopes peering in to the structure and properties of building blocks of matter with ever larger energies or particle intensities. On the other hand, telescopes look outside in to the cosmos to ever greater distances and time. As they become bigger and more powerful, both accelerators and telescopes have been continuously pushing the frontiers of technology in all spheres- detectors & front-end electronics, control, communication and computing. This has resulted in electronics which is smaller, consume less power, faster, more accurate, more reliable and support higher capacities. In this keynote address, the speaker traces over two decades of association in building control and information systems for world's big telescopes such as GMRT (Giant Metre-wave Radio Telescope, 90's) and MACE (Multiple Atmospheric Cerenkov Emission, today) in India and large particle accelerators such as LHC (90's) and FAIR (today). While tracking the evolution of related technology over the years, the talk analyses the choices made, lessons learnt, failures and successes, performance and life cycle management issues.

  • U.W. Vaidya
    BARC, Mumbai, India
  
  Until recently Computer Based Safety and Safety-related Control and Instrumentation systems in Indian NPPs and other nuclear utilities were custom built embedded systems. This approach needs enormous development and verification & validation efforts. Further requirement change management during plant operation becomes intricate due to dependence on custom System Designer. Current scenario worldwide is development of such systems using Qualified Configurable, Programmable Platforms (PLCs) offering several advantages over custom built approach. Trombay Programmable Logic Controller TPLC-32 is one such qualified platform designed and developed in-house by Reactor Control Division, BARC. It facilitates configurable and programmable environment to build safety and safety related Control and Instrumentation Systems. TPLC-32 hardware is designed around 32 bit processor based in-house developed Single Board Computer on VME bus and intelligent Input/Output modules on proprietary I/O bus. The hardware design is carried out as per IEC60987 standard. The Platform software development is carried out following well documented, well controlled, fully reviewable software engineering process based on AERB SG-D25 guide and IEC 80880 standard including verification and validation by an independent team. The Application Development Environment (ADE) software package of TPLC-32 facilitates defining complete system configuration and application development in the form of function block diagrams based on IEC 61131-3 standards. Platform architecture, development process, platform salient features and C&I system developed using TPLC-32 platform will be discussed in the talk.

  This paper presents current status and upgrade plan of a data-acquisition (DAQ) system for SACLA user experiments. The X-ray Free-Electron Laser facility in SPring-8, SACLA, has achieved first SASE lasing in June 2011, and has delivered X-ray laser beams to users from March 2012 [1]. For the user experiments at SACLA, a dedicated DAQ system has been developed. The DAQ system is currently capable to operate with maximum 10 sensors of multiport Charge-Coupled Device (MPCCD) for X-ray detection. With this configuration, the MPCCD generates 10 MBytes data per accelerator beam shot, which is equivalent to 5 Gbps data rate at 60 Hz beam repetition. During the first experimental period from March to July 2012, the DAQ system carried out 25 experimental proposals that covered atom, molecular and optical physics, ultrafast science, material science, and structure biology. In this paper, we present an overview of the DAQ system with special emphasis on the high-speed data cache, and data visualization by on-site PC clusters. An upgrade plan of the DAQ storage more than 3 PBytes and the on-line data-analysis with the off-site 10 PFlops supercomputer ("K computer") are also discussed.

THIA03 The IUAC Tandem-LINAC Control System 94
 
  • A. Kumar, B.K. Sahu, K. Singh
    IUAC, New Delhi, India
  
  The 16MV Tandem Van de Graff accelerator at IUAC is one of the earliest machines to go for a PC based control system. The PDP11, supplied with it, was replaced by an IBM PC running DOS before the accelerator was commissioned in 1989. The present system, commissioned in 1997 to include the LINAC, runs on a network of PCs under the GNU/Linux operating system. We have followed a distributed approach by grouping the signals, around 1000 in total, based on the location. Each group is connected to a server computer, by hardware interfaces like CAMAC, VME and custom hardware. The signals connected to each server PC are handled by a server program and they are accessible to the outside world, over a TCP/IP network, using a unique identifier consisting of a Label, Function and Unit. The features like a user interface, monitoring for alarm conditions, data logging and partial automation are handled by several client programs, communicating to multiple servers to access the hardware. The communication is done by passing a message packet and waiting for the reply. The message consists of the unique signal identifier and commands for setting/reading analog and digital parameter values. The development of the control system also resulted in low cost equipment for science education[1]. It also helped further development of the control system by additions like client programs in Python language. This feature enabled accelerator users to write simple scripts for tasks like setting the LINAC resonator parameters based on calculations, writing routines for partial automation etc. The system is cost effective, scalable and simple. It has shown very high reliability and ease of use during the past two decades of operation.

THCA04 An Update on ConSys Including a New LabVIEW FPGA Based LLRF System 97
 
  • T. Worm, J.S. Nielsen
    ISA, Aarhus, Denmark
  
  ConSys, the Windows based control system for ASTRID and ASTRID2, is now a mature system, having been in operation for more than 15 years. All the standard programs (Console, plots, data logging, control setting store/restore etc.) are fully general and are configured through a database or file. ConSys is a standard publisher/subscriber system, where all nodes can act both as client and server. One very strong feature is the easy ability to make virtual devices (devices which do not depend on hardware directly, but combine hardware parameters.) For ASTRID2 a new LabVIEW based Low-Level RF system has been made. This system use a National Instruments NI-PCIe7852R DAQ card, which includes an on-board FPGA and are hosted in a standard PC. The fast (50 kHz) amplitude loop has been implemented on the FPGA, whereas the slower tuning and phase loops are implemented in the real-time system. An operator interface including live plots from the regulation loops are implemented in a host program on Windows. All three levels have been implemented with LabVIEW. The LLRF system is interfaced to ConSys through LabVIEW shared variables.

  Currently the 10MeV Linac is being used for different research applications and industrial use. The control system in operation was developed using CAMAC based DAS, backed by Hard-wired Interlock System. It is proposed to replace the CAMAC system with a state-of-the-art indigenously developed PLC that is verified to the level of a Class IB computer-based system used in nuclear power plants. A PLC node comprises of two VME bus based CPU boards (PowerPC MPC7447, 600MHz) working in redundant mode. The Inputs and Outputs are common to both CPUs. The intelligent I/O boards are hot swappable. The PLC hardware and software has undergone rigorous verification and validation. A user-friendly development environment is provided to the process engineer for building the application using pre-defined function blocks. The LCS developed using PLC is to be used for operating the Linac irradiation facility, remotely as well as locally in a fail-safe mode, with sequential start-up and sequential shut-down. Apart from system status monitoring, data archiving, alarm generation and setpoint adjustments, it shall monitor the important parameters and trip the GM HV, KM HV and EG PS on fault conditions.

  X-ray imaging permits spatially resolved visualization of the 2D and 3D structure in materials and organisms which is crucial for the understanding of their properties. Additional resolution in the time domain gives insight in the temporal structure evolution and thus access to dynamics of processes allowing to understand functionality of devices and organisms and to optimize technological processes. Such time resolved dynamic analyses ofμsize structures became now possible by the new ultrafast tomography at the TopoTomo beamline of the synchrotron light source ANKA. At TopoTomo the whole experimental workflow has been significant improved in order to decrease the total duration time of a tomography experiment in a range of minutes. To aim the goal of a Tango based control system for ultra fast tomography with a data throughput of several 100 MB/s, detectors and computing infrastructure have been optimized. Multi GPU based computing allows a high speed data processing by using a special reconstruction scheme. Furthermore data management infrastructure will allow a life cycle management of data sets accumulating to several TByte/day.

A 10MeV, Electron beam, RF Linac is operational at EBC, Kharghar, Navi Mumbai. The beam output scans one meter length in a scan horn. The product under irradiation is placed in a conveyor trolley where trolley is one meter long and one meter gap between the trolleys. With the constant speed of 5mtrs/min operation of trolley, the dose utilization is 50% since the beam falls in the gap between the trolleys. We have modulated the speed as 5mtrs./min when trolley gap is under the beam and 0.1 mtrs./min when trolley is under the beam. This way the beam utilization for the irradiation goes up to 98% hence 48% rise in productivity. A 20kV 10KJ Electromagnetic machining (EMM) facility is developed by APPD/BARC. In this EMM facility a large value capacitor is charged by a DC supply to a constant voltage. This charged capacitor is then discharged using triggered spark gap into a coil to generate intense magnetic field. This magnetic field generates the eddy current into the job piece to do the forming. We have used a PLC based control system to control the machine.

The S-DALINAC is a recirculating superconducting electron LINAC which has been in operation for twenty years. The control system had been developed in-house and, while being moderately reliable, has become very hard to maintain and nearly impossible to adapt to new requirements. The replacement of the old analog low-level RF control system by a modern digital solution in 2010 became a primer for the introduction of an EPICS-based control system. Several important subsystems have been migrated since then, but the process has not been completed yet. This contribution overviews the current status of the new control system and developments planned for the future. Basic hardware aspects are described as well as client software and operator interfaces. The general network infrastructure has been restructured in context of the ongoing migration and is also presented.

Feedback control system plays important role for proper injection and acceleration of beam in particle accelerators by providing the required amplitude and phase stability of RF fields in accelerating structures. Advanced digital technologies allow development of control systems for RF applications. Digital LLRF system offers inherent advantages like flexibility, adaptability, good repeatability and low drift errors compared to analog system. For feedback control algorithm, I/Q control scheme is used. Properly sampling of down converted IF generates accurate feedback signal and eliminates the need of separate detector for amplitude and phase. Controller is implemented in Vertex-4 FPGA with proper control algorithm which offers fast correction with good accuracy and also controls the amplitude and phase in all four quadrants. Single I/Q modulator work as common correctors for both amplitude and phase. LO signal is derived from RF signal itself to achieve synchronization between RF, LO and FPGA clock. Control system has been successfully tested in laboratory with phase and amplitude stability better then ± 1% and ±1°. With minor modification same systems can be used at any frequencies.

Long-term objective of this work is to develop a fuzzy technology based control framework to be applied in particle accelerators. Main motivation for this is the promise of fuzzy systems to exploit the tolerance for imprecision, un-certainty, and partial truth to achieve tractability, robustness, and low solution cost. Intended areas of application are manifold: we think on automatic operation, optimization of the operating conditions and yields; applied to various stages in the processing of circular and linear accelerators. As a first step towards this goal a fuzzy control system for a transfer channel in a particle accelerator has been developed. For it we built up the machinery, i.e. algorithms, data structures, integration in the existing control system and did a first proof-of-concept. Special emphasis is given on handling high dimensional data streams and the immanent challenges as sparsity and equidistance of the data.

  The K500 Superconducting Cyclotron at VECC, Kolkata uses two electrostatic deflectors, eight passive magnetic channels, one active magnetic channel and two compensating bars as its extraction elements. Except the active magnetic channel, all the other elements can be moved radially, typically by ±6 mm around a centre position. This maneuverability is due to the fact that not all the ions, spanning the operating region of the cyclotron, will have the same optimum beam extraction radius. At the end of the beam extraction channel, the beam is shaped and aligned by a pair of water cooled slit. The slit movement is pneumatically controlled as it has to be operated in high magnetic field. The computer controlled drive system can move the elements precisely. The paper will describe the drive system and its control mechanism.

  RIB facility at VECC has several heavy ion linear accelerators like RFQ, two IH-LNACs and one buncher cavity operating at 37.8 MHz and two IH-LINACs with one buncher cavity at 75.6 MHz. Some more RF cavities are being designed at the third harmonic of 37.8 MHz and will be added in the RIB beam line. All the cavities have separate RF power amplifiers with proper amplitude, phase and resonance frequency tuning and control system for efficient and stable operation. The LLRF control system has been operational for the power amplifiers of the existing RF cavities and improved design and development is carried out. The main features of the RF control system are phase and amplitude control of the RF input to the amplifiers and tuning of the RF cavity to the desired resonant frequency with automation using feedback control. It will also have various interlocks for the safety of the load as well as the amplifier. A micro-controller based data acquisition and processing system is being used for control and local/remote operation. The RF distribution system as well as the design details of RF control system will be presented in this paper.

Computerised controls are vital to the operability and flexibility of large-scale physics facilities (such as accelerators, synchrotrons and high-power lasers) in providing fundamental services, for example, automatic configuring of specialist hardware, motion control, firing of shot sequences, enabling precision trigger distribution, vacuum monitoring and control, data acquisition and analysis. The proposed 10PW Laser facility, in line with other major physics facilities around the world, will require a complex computer control system. This is expected to be modeled on the existing Vulcan Laser[1] control system and consist of a dozen or so Windows based PCs each of which will be running a separate and dedicated application to control a particular area or function of the facility. This paper will present an overview of the existing Vulcan laser and provide a status report on the development towards the 10PW which will require the control system to be designed to allow autonomous operation of the 10PW facility as well as to be fully integrated with the existing Vulcan laser controls for combined and synchronized 10PW plus 1PW operations.

This paper describes a distributed embedded system that uses a high performance mixed signal controller C8051F040 for its DAQ nodes and is based on CAN bus protocol for remote monitoring and controlling of various subsystems of 750 keV DC accelerator based irradiation facility at RRCAT, Indore. A PC with integrated PCI CAN card communicates with intelligent DAQ nodes over CAN bus and each node is interfaced with a subsystem. An opto- isolated SN65HVD230 CAN driver is interfaced between each node and physical bus. Remote frames and message prioritizing are used for efficient control. The PC application is developed using LabVIEW 8.6. The proposed system is more reliable and noise immune as compared to previously [1] used systems that initially used a centralized system based on C8051 controller. This was then upgraded [2] to a distributed system that used micro-controller AduC812 and communicated over RS485 link. The new system has been integrated and tested satisfactorily for its designed performance with test jigs that simulated the actual subsystems with a bus length of 75 meters. First the complete scheme of the system is presented, then the hardware and software designs are discussed.

The Indus-2 synchrotron radiation source has four RF stations along with their feedback control systems. For higher beam energy and current operation, amplitude and phase feedback control systems of Indus-2 are being upgraded. To understand the behavior of amplitude and phase control loop under different operating conditions, modeling and simulation of RF feedback control system is done. RF cavity base band quadrature domain model has been created due to its close correspondence with actual implementation and better computational efficiency which make the simulation faster. Correspondence between base band and actual RF cavity model is confirmed by comparing their simulation results. Base band Cavity model was studied under different operating conditions. LLRF feed back control system simulation is done using the same cavity model. Error signals are intentionally generated and response of the closed loops system is observed. With implementation of feedback control loop, broadening in the RF cavity bandwidth was also observed in terms of reduction in cavity fill time. Simulation will help us in optimizing parameters of upgraded LLRF system for higher beam energy and current operation.

High specific activity 99Mo is supplied globally mainly by five old reactors whose routine or unscheduled maintenance shutdown causes supply irregularities that adversely affects patient management in nuclear medicine centres. 99mTc may also be produced via 98Mo(n,γ) in a natural MoO3 target in reactor or by 100Mo(n,2n)99Mo or 100Mo(p,2n)99mTc reaction in cyclotron. To meet the crisis proposals are there to produce 99Mo by 100Mo(n,2n)99Mo or 99mTc directly by 100Mo(p,2n)99mTc in a cyclotron. Of the several separation methods of 99mTc from molybdenum, the most common are adsorption column chromatography, sublimation and liquid-liquid solvent extraction. The conventional methods besides being cumbersome are often hazardous, polluting, require skilled manpower and facilities like fume hood and so are not always practically feasible for hospitals. To address these, VECC and BRIT, Kolkata have collaborated to develop an embedded system based automated 99Mo/99mTc generator from low specific activity 99Mo using solvent extraction technique, supervised by a PC based GUI.

    GSI, Darmstadt, Germany
  
  At the GSI accelerator complex in Darmstadt Germany the linear decelerator HITRAP is currently under commissioning. The aim is to provide highly charged ions up to bare uranium at cryogenic temperatures for various experiments as for instance tests of the theory of quantum electrodynamics. The ions are delivered with kinetic energies of about 4 MeV/u from GSIs experimental storage ring (ESR) and are slowed down in several steps until they are trapped and cooled down in a Penning trap. Whereas for the ESR as well as for the first sections of the linear decelerator the GSI accelerator control system is used the cooler trap as well as the subsequent transfer section to the experimental area are controlled with the LabVIEW based CS-framework developed at GSI. This framework is an object-oriented, event driven and multi-threaded framework with SCADA functionality, which is currently in use at many different experiments world-wide. For the HITRAP facility additional features like an online beam monitoring, realized with the integration of a LVOOP class capable of reading out IMAQ cameras, as well as a new GUI were implemented, which allows automatic scans of beam elements.

  Control system for RF source of 30 MeV, 3 kW RF Linac for neutron generation is being developed. The system consists of two 15 MeV linac structures, each powered independently with klystron rated for 7.5 MW(pk)/7.5 kW(avg). Two klystron modulators of 160kV, 110A, 7usec and 250Hz feed pulsed power into the klystron, which produces RF power at 2856 MHz. The klystrons will be driven by low power RF driver amplifiers programmed for matching phase, frequency and power into the linac. Both the driver amplifiers are controlled through RS-232 Protocol. The HV pulsing and RF drive for the klystron has been interlocked with water flow, arc detector, SF6 gas pressure etc. The control system is designed using Real time embedded controller, where pulses for synchronization are being generated in FPGA. Most of the power supplies like electromagnet, HVDC, etc. are on RS-232 protocol. These power supplies are controlled via suitable RS-232 to Ethernet converter. State machine topology is being used to design the logic. The database for logging data is developed in SQL. This paper describes the details of the software implementation and hardware used to realize the control of the RF power source.

  A new timestamp and event distribution system for the upcoming FAIR facility is being developed at GSI. This timing system is based on White Rabbit[1], which is a fully deterministic Ethernet-based network for general data transfer and synchronization. White Rabbit is developed by CERN, GSI and other institutes as well as partners from industry based on Synchronous Ethernet and PTP. The main tasks of the FAIR timing system are time synchronization of more than 2000 nodes with nanosecond accuracy, distribution of timing messages and subsequent generation of real-time actions (interrupts, digital signals …) by the nodes of the timing system. This allows precise real-time control of the accelerator equipment according to the beam production schedule. Furthermore the timing system must support other accelerator systems like post-mortem and interlock. It also provides interfaces between the accelerator control system and experiments at FAIR. This contribution focuses on the design principles of the timing system, its integration with other components of the control system, the present status and the planned implementation.

  The Cryogenic Data Acquisition and Control system (CRYO-DACS) at IUAC was commissioned successfully in the year 2002 and has been continuously in operation since then with uptime better than 95%. The aim of CRYO-DACS is to control and acquire many analog and digital cryogenic parameters of super conducting LINAC and related equipments like beam-line cryostats, helium compressors, cryogenic distribution etc. The complete system is implemented using two VME crates, housing I/O modules, placed far apart and interconnected using Ethernet. The software implementation and maintenance have also been trouble-free which used IOWORKS as the development tool for embedded CPUs running VxWORKS. The OPC Client was developed using VB6 & MSACCESS RDBMS for data logging, viewing and trending under Windows 2000 stable server. In summary, this paper will elaborate the implementation, use and related failures faced for last 10 years and the subsequent corrective actions taken to keep the system running for such a long time round the clock along with some future plans.

The sub-detectors of the Compact Muon Solenoid (CMS) multi-purpose particle detector at the CERN Large Hadron Collider (LHC) have been collecting physics data from particle collisions for almost three years. During this period, the Electromagnetic Calorimeter (ECAL) Detector Control System (DCS) has contributed to the high level of availability of the experiment. This paper presents the current architecture of this distributed and heterogeneous control system alongside plans and developments for future improvements. To ensure that the system can efficiently operate and adapt to changes throughout the required operation lifetime of more than a decade, the potential legacy aspects of this kind of control system must be carefully managed. Such issues include evolving system requirements, turnover of staff members, potential benefits from new technologies and the need to follow release schedules of external software dependencies. The techniques and results of the work to continually maintain, improve and streamline the control system are presented, including the use of metrics to evaluate the impact of this effort.

  An RF control system has been developed for the 400 keV, 350 MHz RFQ coming up at BARC. This single cavity system consists of the functionalities of amplitude stabilization and frequency tracking for both continuous and pulsed mode of operation. The amplitude stabilization is implemented by modulating the attenuation across a fast modulator placed in the drive path. The frequency tracking is achieved by driving the FM port of a signal generator with a signal proportional to the phase shift across the resonator. The whole system is under computer control via CAMAC hardware. The paper describes the system architecture, housing & wiring of the system in a single instrumentation rack and development & testing of computer control.
