MO2AB1	Beam Measurements Using Schottky Signal Analysis
	P. Forck, P. Kowina, R. Singh GSI, Darmstadt, Germany M. Wendt CERN, Geneva, Switzerland
	Schottky signal analysis is a non-invasive beam measurement method based on the observation of the electromagnetic properties of individual beam particles. It allows the determination of important parameters such as momentum spread, synchrotron tune, coherent and incoherent betatron tune, and chromaticity for coasting and bunched beams at hadron synchrotrons. It is a popular diagnostic at low energy ion storage rings as well as implemented for bunched beams in high energy synchrotrons such as LHC. In this tutorial, the underlying physics for the observables will be described together with the basic mathematics. Recent results for high intensity beam will be discussed. The detector technology, based on capacitive pick-ups, traveling wave structures, or cavities is addressed, as well as the associated rf electronics to extract this weak, beam induced Schottky signal. Applications ranging from the daily operational usage up to dedicated machine physics investigations on a very wide range of beam parameters will be discussed.

	Funding: Work supported by The National Key Research and Development Program of China, with grant No. 2016YFC0105305, and by National Natural Science Foundation of China (11375068). Proton therapy is now recognized as one of the most effective radiation therapy methods for cancers. A proton therapy facility with multiple gantry treatment rooms is under development in HUST (Huazhong University of Science and Technology), which is based on isochronous superconducting cyclotron scheme. The 250MeV/500nA proton beam will be extracted from a superconducting cyclotron and injected into the beam-line. Many beam diagnostic instruments are distributed throughout the beam line to measure the beam profile, position, current, loss, energy and energy spread. Some of them will send the beam information to the treatment control system (TCS) and serve as the safety interlock. This paper presents the considerations for the distribution of beam diagnostic instruments and shows the layout of beam diagnostics monitors in the beamline.

	The multipurpose CW accelerator ELBE at HZDR, which is delivering a large set of secondary beams, is driven by a thermionic DC injector. In order to enhance the machine's beam quality, the development of a superconducting RF injector has been pursued since the early 2000ies. The corresponding ELBE SRF Gun I of 2007 and Gun II of 2014 already delivered beam for the operation of several user beamlines, such as the FEL, positron generation, and THz facility. Currently, the next version ' Gun III ' and its cryomodule are being assembled, characterized, and prepared for the final commissioning throughout late 2017/early 2018. The new module benefits from the experiences in terms of emittance compensation and surveillance of operation variables made with the two predecessors. Results of the latest Gun II operations as well as first commissioning data of the Gun III module will be presented.

	R. Takai, T. Honda, T. Obina, H. Sagehashi, M. Tadano KEK, Ibaraki, Japan
	The beam transport line (BT) for the Photon Factory Advanced Ring (PF-AR), which is a 6.5-GeV light source of KEK, has been recently renewed. The new BT dedicated to PF-AR allows not only simultaneous operation with the SuperKEKB storage ring, which has a much shorter Touschek lifetime, but also the top-up operation via 6.5-GeV full-energy injection. The construction, including tunnel excavation, was completed by the end of 2016, and the commissioning was performed for one month from February 2017. Standard beam monitors, such as stripline beam position monitors, screen monitors, beam loss monitors, and fast current transformers are installed in the new BT and contribute greatly to accomplishing the commissioning in a short period of time. This paper discusses details of these monitors and some commissioning results obtained by using them.

TU2AB2	Beam Diagnostics for the AWAKE Experiment
	M. Martyanov MPI-P, München, Germany
	In this talk an overview of the beam instrumentation of the advanced wake field experiment (AWAKE) hosted at CERN will be given. The AWAKE project is a proof-of-principle experiment, which aims at accelerating a witness electron bunch in a plasma wake excited by a proton bunch coming from the LHC pre-accelerator, the Super Proton Synchrotron (SPS). Various numerical simulations showed that the charge density within a relatively long (ns-scale) SPS proton bunch experiences a self-modulation instability (SMI) propagating in a plasma and tends to be radially (not longitudinally, no micro-bunches in a common sense) modulated with the plasma oscillation period (on the order of 3-10 ps in AWAKE case). The experimental observation and quantitative analysis of a proton bunch radial density modulation would be an experimental proof of the effective plasma wake excitation. This talk is focused mainly on the various diagnostics that include: Rb vapor density diagnostics, optical transition radiation (OTR) and microwave coherent transition radiation (CTR) setups to measure the SMI frequency, proton beam halo diagnostic to verify the defocused part of a bunch.

	Several large-scale oil spills typically occur in the USA and other places around the world. Such events threaten the Great Lakes as well. The cleanup process is not necessarily efficient or environmentally safe. In addition, the remediation and recovery process is time consuming, expensive and can lead to harmful environmental effects. An innovative electromagnetic approach by Natural Science, LLC uses materials that are reusable, recoverable, and environmentally safe. When micron-sized magnetite (Fe3O4) particles are dispersed in oil on water, the particles form a unique and preferential bond with the oil due to a combination of forces, e.g. Van der Waals. Magnetic fields can then be used to manipulate, trap and remove the oil in an environmentally safe manner with high efficiency. In the case of oil spills on water, the water becomes the primary transport medium for manipulating the oil. Videos demonstrating the process will be shown. Both the particles and the oil are recaptured and separated for reuse. This process is being applied to electromagnetic systems that can replace and/or increase the efficiency of the passive boom and skimmer systems used today.

WE1AB2	Diagnostic Challenges at LCLS-II and Lessons Learned from LCLS-I at SLAC
	P. Krejcik SLAC, Menlo Park, California, USA
	SLAC is replacing the first km of its 3-km linac with a CW superconducting linac at 1.3 GHz for the LCLS-II x-ray FEL. A laser will drive a normal-conducting 186-MHz CW photocathode gun with arbitrary pulse separation at up to 1 MHz. In addition to the standard SASE x-ray beam, users will continue to have access to special operating modes such as seeded beams or double pulses with selectable separation and wavelength separation. The accelerator will begin operation with an average power of 240 kW, later rising to 1 MW. The existing 120-Hz LCLS-I copper linac will operate simultaneously in the third km. A pulsed beam "spreader" can direct each pulse from each linac into one of two new undulators, for hard and soft x rays, or into a dump. This talk will discuss the extensive measurements and feedbacks along the 4-km path that are in preparation to monitor and maintain beam quality and FEL performance through this wide parameter range.

WE1AB3	Overview of the Diagnostics of the ELI-NP Gamma Beam System: Challenges for the Electron-Photon Interaction Point Diagnostics
	A. Mostacci Rome University La Sapienza, Roma, Italy A. Variola INFN/LNF, Frascati (Roma), Italy
	The Extreme Light Infrastructure-Nuclear Physics (ELI-NP) facility is currently under construction near Bucharest (Romania); it will focus on laser-based fundamental research on nuclear physics. The facility will host two 10 PW laser systems and an advanced gamma beam source, called Gamma Beam System (GBS). GBS is a photon electron collider producing gamma rays from Compton back scattering of a laser light off a high charge, low emittance electron beam from a 720 MeV warm linac. The gamma rays will have tunable energy (1-20MeV) with worldwide outstanding performances, such as narrow bandwidth (0.3%) and high spectral density (10⁴ photons/s/eV). To achieve such challenging performances, the luminosity will be raised by colliding up to 32 electron bunches with a properly recirculated laser beam. New class diagnostics need to be developed at the interaction point to allow efficient photon electron collisions. This infrastructure will create a new European laboratory with a broad range of science covering frontier fundamental physics, new nuclear physics and astrophysics as well as applications in nuclear materials, radioactive waste management, material science and life sciences.

Proton therapy is now recognized as one of the most effective radiation therapy methods for cancers. A proton therapy facility with multiple gantry treatment rooms is under development in HUST (Huazhong University of Science and Technology), which is based on isochronous superconducting cyclotron scheme. The 250MeV/500nA proton beam will be extracted from a superconducting cyclotron and injected into the beam-line. Many beam diagnostic instruments are distributed throughout the beam line to measure the beam profile, position, current, loss, energy and energy spread. Some of them will send the beam information to the treatment control system (TCS) and serve as the safety interlock. This paper presents the considerations for the distribution of beam diagnostic instruments and shows the layout of beam diagnostics monitors in the beamline.

The multipurpose CW accelerator ELBE at HZDR, which is delivering a large set of secondary beams, is driven by a thermionic DC injector. In order to enhance the machine's beam quality, the development of a superconducting RF injector has been pursued since the early 2000ies. The corresponding ELBE SRF Gun I of 2007 and Gun II of 2014 already delivered beam for the operation of several user beamlines, such as the FEL, positron generation, and THz facility. Currently, the next version ' Gun III ' and its cryomodule are being assembled, characterized, and prepared for the final commissioning throughout late 2017/early 2018. The new module benefits from the experiences in terms of emittance compensation and surveillance of operation variables made with the two predecessors. Results of the latest Gun II operations as well as first commissioning data of the Gun III module will be presented.

The new system enables a higher flexibility, better performance and more advanced diagnostics. The contribution will show the performance of the system at ELBE, the hardware and the software structure. Further it will summarize the last steps to bring it into full user operation and give an outlook to the envisioned beam-based feedback system that will take advantage of the capabilities of the digital LLRF system.

The beam transport line (BT) for the Photon Factory Advanced Ring (PF-AR), which is a 6.5-GeV light source of KEK, has been recently renewed. The new BT dedicated to PF-AR allows not only simultaneous operation with the SuperKEKB storage ring, which has a much shorter Touschek lifetime, but also the top-up operation via 6.5-GeV full-energy injection. The construction, including tunnel excavation, was completed by the end of 2016, and the commissioning was performed for one month from February 2017. Standard beam monitors, such as stripline beam position monitors, screen monitors, beam loss monitors, and fast current transformers are installed in the new BT and contribute greatly to accomplishing the commissioning in a short period of time. This paper discusses details of these monitors and some commissioning results obtained by using them.

In the framework of the LHC Injector Upgrade (LIU) project, the Proton Synchrotron Booster (PSB) will be extensively modified during the Long Shutdown 2 (LS2, 2019-2020) at CERN [1]. This includes a new injector, Linac4, which will provide a 160 MeV H⁻ beam and a complete new injection section for the PSB composed essentially of a chicane and a stripping foil system. The equivalent of half of this new injection chicane, so-called Half-Sector Test (HST), was tempo-rarily installed in the Linac4 transfer line to evaluate the performance of the novel beam instrumentation, such as, stripping foils, monitoring screens, beam cur-rent transformers, H⁰/H⁻ monitor and dump, beam loss monitors, and beam position monitors. The results of the instrumentation commissioning of the HST are presented in this paper.

Beam Diagnostics for the AWAKE Experiment

M. Martyanov
MPI-P, München, Germany

In this talk an overview of the beam instrumentation of the advanced wake field experiment (AWAKE) hosted at CERN will be given. The AWAKE project is a proof-of-principle experiment, which aims at accelerating a witness electron bunch in a plasma wake excited by a proton bunch coming from the LHC pre-accelerator, the Super Proton Synchrotron (SPS). Various numerical simulations showed that the charge density within a relatively long (ns-scale) SPS proton bunch experiences a self-modulation instability (SMI) propagating in a plasma and tends to be radially (not longitudinally, no micro-bunches in a common sense) modulated with the plasma oscillation period (on the order of 3-10 ps in AWAKE case). The experimental observation and quantitative analysis of a proton bunch radial density modulation would be an experimental proof of the effective plasma wake excitation. This talk is focused mainly on the various diagnostics that include: Rb vapor density diagnostics, optical transition radiation (OTR) and microwave coherent transition radiation (CTR) setups to measure the SMI frequency, proton beam halo diagnostic to verify the defocused part of a bunch.

Several large-scale oil spills typically occur in the USA and other places around the world. Such events threaten the Great Lakes as well. The cleanup process is not necessarily efficient or environmentally safe. In addition, the remediation and recovery process is time consuming, expensive and can lead to harmful environmental effects. An innovative electromagnetic approach by Natural Science, LLC uses materials that are reusable, recoverable, and environmentally safe. When micron-sized magnetite (Fe3O4) particles are dispersed in oil on water, the particles form a unique and preferential bond with the oil due to a combination of forces, e.g. Van der Waals. Magnetic fields can then be used to manipulate, trap and remove the oil in an environmentally safe manner with high efficiency. In the case of oil spills on water, the water becomes the primary transport medium for manipulating the oil. Videos demonstrating the process will be shown. Both the particles and the oil are recaptured and separated for reuse. This process is being applied to electromagnetic systems that can replace and/or increase the efficiency of the passive boom and skimmer systems used today.

Diagnostic Challenges at LCLS-II and Lessons Learned from LCLS-I at SLAC

P. Krejcik
SLAC, Menlo Park, California, USA

SLAC is replacing the first km of its 3-km linac with a CW superconducting linac at 1.3 GHz for the LCLS-II x-ray FEL. A laser will drive a normal-conducting 186-MHz CW photocathode gun with arbitrary pulse separation at up to 1 MHz. In addition to the standard SASE x-ray beam, users will continue to have access to special operating modes such as seeded beams or double pulses with selectable separation and wavelength separation. The accelerator will begin operation with an average power of 240 kW, later rising to 1 MW. The existing 120-Hz LCLS-I copper linac will operate simultaneously in the third km. A pulsed beam "spreader" can direct each pulse from each linac into one of two new undulators, for hard and soft x rays, or into a dump. This talk will discuss the extensive measurements and feedbacks along the 4-km path that are in preparation to monitor and maintain beam quality and FEL performance through this wide parameter range.

INFN/LNF, Frascati (Roma), Italy

The Extreme Light Infrastructure-Nuclear Physics (ELI-NP) facility is currently under construction near Bucharest (Romania); it will focus on laser-based fundamental research on nuclear physics. The facility will host two 10 PW laser systems and an advanced gamma beam source, called Gamma Beam System (GBS). GBS is a photon electron collider producing gamma rays from Compton back scattering of a laser light off a high charge, low emittance electron beam from a 720 MeV warm linac. The gamma rays will have tunable energy (1-20MeV) with worldwide outstanding performances, such as narrow bandwidth (0.3%) and high spectral density (10⁴ photons/s/eV). To achieve such challenging performances, the luminosity will be raised by colliding up to 32 electron bunches with a properly recirculated laser beam. New class diagnostics need to be developed at the interaction point to allow efficient photon electron collisions. This infrastructure will create a new European laboratory with a broad range of science covering frontier fundamental physics, new nuclear physics and astrophysics as well as applications in nuclear materials, radioactive waste management, material science and life sciences.
