TUPMB047	Tracking the Helium Balance in FREIA	database, controls, hardware, radio-frequency	1202
	V.G. Ziemann, L. Hermansson Uppsala University, Uppsala, Sweden
	In the FREIA laboratory at Uppsala University we test the super-conducting spoke-cavities for the European Spallation Source. Liquid Helium for cooling the cavities is provided by a liquefaction plant from which also a local user community at the University is served. Recently we encountered a leak due to a faulty valve which went undetected for some time and caused significant loss of Helium. In order to prevent such mishaps in the future we implemented a Helium tracking system that includes detailed accounting of Helium leaving and entering the closed system as well as all volumes containing Helium in the system. We describe the technical implementation and experience to date.

WEPOR003	Voltage Control for the 4-Th Harmonic Cavity in Hls Storage Ring	cavity, controls, feedback, storage-ring	2664
	K. Xuan, C. Li, J.Y. Li, G. Liu, W. Xu USTC/NSRL, Hefei, Anhui, People's Republic of China
	In order to increase the beam lifetime, a 4th harmonic RF cavity was installed in the HLS-II storage ring. The electrical fields in the principle cavity and high harmonic cavity stretch the beam in the longitudinal direction, and increase the beam volume in phase space, leading to a longer Touschek lifetime. Stable electrical voltage in the high harmonic cavity is essential for steady beam stretching and better beam lifetime. To get a stable high voltage in the high harmonic cavity, we develop a method to maintain steady resonance condition in the cavity using a PID scheme. This paper presents the details of this method. The feedback result is also reported.

THPOY003	The Turn-key Control System for the ELI-NP Gamma Beam System	controls, laser, timing, electron	4091
	S. Pioli, G. Di Pirro INFN/LNF, Frascati (Roma), Italy F. Amand, V.A. Isaev, A. Jesenko, A. Manojlovic, R. Modic, I. Mustac, G. Pajor Cosylab, Ljubljana, Slovenia B.G. Martlew, A. Oates STFC/DL, Daresbury, Warrington, Cheshire, United Kingdom
	The new Gamma Beam System (GBS) under construction in Magurele (RO) by the consortium EuroGammas led by INFN, as part of the ELI-NP project, can provide gamma rays that open new possibilities for nuclear photonics and nuclear physics. In the ELI-GBS, gamma rays are produced by means of Compton back-scattering to get mono-chromaticity (0,1% bandwidth), a high flux (10¹³ photon/s the highest in the world), tunable directions and energies up to 19 MeV. Such gamma beam characteristic is obtained when a high-intensity laser collides a high-brightness electron-beam with energies up to 720 MeV. In order to increase the gamma beam flux, the electron beam operates at a repetition rate of 100 Hz in a multi-bunch mode: trains of 32 bunches, 16 ns apart, interact with the laser pulse recirculated 32 times through the interaction point. The EPICS Control System collects data from all sub-systems, constantly monitoring to ensure the safety of the ELI-GBS facility. This paper describes all the aspects of the ELI-GBS turn-key Control System, such as hardware integration, micro-bunches diagnostics, high level applications, the data network and the pico-second timing system.

	S. Ma, C. Li, G. Liu, J.G. Wang, W. Xu, K. Xuan USTC/NSRL, Hefei, Anhui, People's Republic of China
	Synchrotron radiation light sources have been becoming import scientific tools in various research areas. To build a state-of-the-art synchrotron radiation light source, one need to carefully study the linear and nonlinear dynamics of the charged beam in each of the light source components, such as the linac, transfer line, booster synchrotron and storage ring. There are many mature software tools, including MAD, elegant and Accelerator toolkit (AT), can be used to accomplish these tasks. In order to achieve a high performance light source, up-to-date technologies are adopt to build various subsystems. The integration of these subsystems need to be fully tested before the light source is operated. However, there lacks of a good software to perform this work. The virtual light source (VLS), a software based upon EPICS and AT, is developed at the National Synchrotron Radiation Laboratory (NSRL) to fulfill this purpose. This paper presents the details of this software. Some critical applications are also illustrated.

	M.J. Park, H. Jang, S. Lee, C.W. Son, H.J. Son IBS, Daejeon, Republic of Korea S.H. Nam Korea University, Seoul, Republic of Korea
	The Rare Isotope Science Project (RISP) Control System is comprised of ethernet-based devices and equipment. Control system is based on Experimental Physics and Industrial Control System (EPICS) Framework, known as a distributed control system through network. So, we need a way for integrating ethernet-based devices into EPICS Framework. Most of these devices support Simple Network Management Protocol (SNMP). SNMP is based on the manager and agent model and it is similar to EPICS Channel Access (CA) protocol. Therefore, SNMP helps to develop a unified network-based control system with EPICS. In this paper, we will show the network device monitoring system RAON customized SNMP integration into EPICS.

THPOY013	Signal Archiving System for RISP Heavy-ion Accelerator Control System	controls, heavy-ion, ion, framework	4113

	RISP control system uses the EPICS real time distributed control system, which is software framework for stable operation of the accelerator. The output signal from all machines and devices must be archived by EPICS framework, and optimized signal archiver system is needed for each accelerator facility. Signal archiver method using the EPICS framework has three significant ways. First is the classic channel archiver using the file base method and the second is the RDB archiver using the relational database. But classic channel archiver has a problem that the index file containing information of data block corresponding PV data mismatch with real data. Also, there is a problem in the performance of file I/O in RDB archiver. SLAC has developed archiver appliance utility to resolve these problems, and the usage of archiver appliance in EPICS community has gradually increased. RISP choose the archiver appliance to also signal archiver solution. However, archiver appliance is not optimized for our RISP heavy-ion accelerator control system. Thus, we will develop the customized signal archiver system for RISP heavy-ion accelerator control system.

	Funding: This work is being supported by the Euratom research and training programme 2014-2018 under grant agreement N°662186 (MYRTE project). The goal of the MYRRHA project is to demonstrate the technical feasibility of transmutation in a 100 MWth Accelerator Driven System by building a new flexible irradiation complex in Mol (Belgium). The MYRRHA facility requires a 600 MeV linear accelerator delivering a maximum proton flux of 4 mA in continuous operation, with an additional requirement for exceptional reliability. The control system of the future MYRRHA linac will have an essential role to play in this extreme reliability scenario. On the one hand the intrinsic reliability of the entire control system must be ensured. On the other hand control system will have to take up very high level duties of complex decision taking. This paper summarizes the ongoing developments for the concept design of such a control system. The related experimental activities performed and planned around the MYRRHA injector platform (ECR ion source + LEBT + RFQ) will also be described.

THPOY051	Upgrades to the SPEAR3 Single-Photon Bunch Measurement System	timing, controls, software, interface	4223
	T.M. Cope, S. Allison, W.J. Corbett, Y.H. Xu SLAC, Menlo Park, California, USA
	The SPEAR3 accelerator uses a Single Photon Time-Correlated Counting (TCSPC) system to accurately measure the time profile of electron bunches circulating in the storage ring. The detection hardware uses the PicoHarp 300 TCSPC processor module initially equipped with an available Hamamatsu H7360-01 photon counting head. The H7360-01 was later replaced with a PicoQuant Hybrid-06 PMA to decrease single-photon arrival time jitter. At the same time we adopted an EPICS-based TCSPC software package developed at DIAMOND for robust data acquisition and display. In this paper we report on recent beam profile measurements and upgrades to the data acquisition software system including installation of a local EPICS IOC for real-time access to the bunch profile from SLAC's centralized Accelerator Control Room (ACR). High-level operator interface and monitoring applications developed in Python are discussed.

In the FREIA laboratory at Uppsala University we test the super-conducting spoke-cavities for the European Spallation Source. Liquid Helium for cooling the cavities is provided by a liquefaction plant from which also a local user community at the University is served. Recently we encountered a leak due to a faulty valve which went undetected for some time and caused significant loss of Helium. In order to prevent such mishaps in the future we implemented a Helium tracking system that includes detailed accounting of Helium leaving and entering the closed system as well as all volumes containing Helium in the system. We describe the technical implementation and experience to date.

The Radiation Equipment Research Division of the Korea Atomic Energy Research Institute has been op-erating a 10 MeV RF electron linear accelerator, which is used for electron beam irradiation. The beam power and energy of the RF electron linear accelerator are 10 kW and 10 MeV. The accelerator is composed of an electron gun, an S-band (= 2856 MHz) accelerating structure, a klystron, electromagnetic solenoids, a scanning electromagnet, an RF driver, a modulator, and a chiller. The linac components have deteriorated due to a long operation time of 9 years. In this paper, we described Experimental Physics and Industrial Control System (EPICS) to control ODA magnet power sup-plies for solenoids and steering magnets of the 10 MeV electron beam irradiation accelerator.

Pohang Accelerator Laboratory(PAL) has been developing a SASE X-ray Free Electron Laser based on 10 GeV linear accelerator. The cavity BPM mover was developed to be used in the intersections of the Undulator Systems. The main specifications include submicron repeatability for a 50 kg cavity BPM adjusting system within compact dimensions and a ±1.5 mm stroke in the vertical and horizontal direction. Compact linear motion guide based on 5-phase stepping motors have been chosen. A closed-loop control system has been developed to achieve this repeatability. For the feedback, one digital probe sensor for each axis was used. Mechanical switches are used to limit movement. In addition, hard-stops are included for emergency. In this report, we describe the design of the stages used for precise movement and results of mechanical measurements including reproducibility will be reported.

In order to increase the beam lifetime, a 4th harmonic RF cavity was installed in the HLS-II storage ring. The electrical fields in the principle cavity and high harmonic cavity stretch the beam in the longitudinal direction, and increase the beam volume in phase space, leading to a longer Touschek lifetime. Stable electrical voltage in the high harmonic cavity is essential for steady beam stretching and better beam lifetime. To get a stable high voltage in the high harmonic cavity, we develop a method to maintain steady resonance condition in the cavity using a PID scheme. This paper presents the details of this method. The feedback result is also reported.

The Integrated Control System Division (ICS) at the European Spallation Source (ESS) has the mandate to provide all the needed tools to ESS staff, in-kind contributors and consultants spread all over Europe, in order for them to build software for the commissioning and operation of the ESS. This includes EPICS applications, scripting environments, physics simulators and commissioning tools among others. ICS needs to provide support for new releases of the different software components, guaranteeing that the development environment of all the users can be properly updated. ICS needs to guarantee as well that environments can be reproducible and at the same time give the flexibility to users to own and customize their environments. ICS used a new virtualization technology (Vagrant) and a new configuration management system (Ansible) to provide a cutting edge development environment where all the software infrastructure can be described as code and properly stored in a version control system, tagged, tested, versioned and rollbacked if needed.

During the commissioning phase of the HLS-II storage ring, the betatron function, the natural chromaticity, the corrected chromaticity and the central RF frequency were measured using the Swept-Frequency-Exitation based tune measurement system. The betatron function was measured using the quadrupole modulation method. The natural chromaticity and the corrected chromaticity were measured using the dipole modulation method and the RF modulation method respectively. In addtion, the central RF frequency was measured using the sextupole modulation method, which can be viewed as a direct measure of the ring circumference. This paper describes the measurement details and presents the measurement results.

A control system has been designed for the commissioning of 10 MeV linear accelerator which is under construction in institute for research in fundamental science (IPM). The IPM e-Linac is a traveling wave accelerator consisting of 62 components in five major sections: control and safety, beam injection, radio frequency production and transmission, acceleration tube and target. The existence of a central control system for controlling and monitoring all parts of the machine is necessary. The aim of the system design is to implement a fast and reliable control system which is easy to operate and extensible for future upgrades and improvements. For this purpose, EPICS has been chosen as the main environment due to high performance and distributed structure. In this system, Siemens PLC is used as EPICS IOC and graphical designs will performed by CSS and WinCC. In this study, first we present a brief description of the IPM electron linear accelerator, and then architecture of the control system will be discussed.

The new Gamma Beam System (GBS) under construction in Magurele (RO) by the consortium EuroGammas led by INFN, as part of the ELI-NP project, can provide gamma rays that open new possibilities for nuclear photonics and nuclear physics. In the ELI-GBS, gamma rays are produced by means of Compton back-scattering to get mono-chromaticity (0,1% bandwidth), a high flux (10¹³ photon/s the highest in the world), tunable directions and energies up to 19 MeV. Such gamma beam characteristic is obtained when a high-intensity laser collides a high-brightness electron-beam with energies up to 720 MeV. In order to increase the gamma beam flux, the electron beam operates at a repetition rate of 100 Hz in a multi-bunch mode: trains of 32 bunches, 16 ns apart, interact with the laser pulse recirculated 32 times through the interaction point. The EPICS Control System collects data from all sub-systems, constantly monitoring to ensure the safety of the ELI-GBS facility. This paper describes all the aspects of the ELI-GBS turn-key Control System, such as hardware integration, micro-bunches diagnostics, high level applications, the data network and the pico-second timing system.

Synchrotron radiation light sources have been becoming import scientific tools in various research areas. To build a state-of-the-art synchrotron radiation light source, one need to carefully study the linear and nonlinear dynamics of the charged beam in each of the light source components, such as the linac, transfer line, booster synchrotron and storage ring. There are many mature software tools, including MAD, elegant and Accelerator toolkit (AT), can be used to accomplish these tasks. In order to achieve a high performance light source, up-to-date technologies are adopt to build various subsystems. The integration of these subsystems need to be fully tested before the light source is operated. However, there lacks of a good software to perform this work. The virtual light source (VLS), a software based upon EPICS and AT, is developed at the National Synchrotron Radiation Laboratory (NSRL) to fulfill this purpose. This paper presents the details of this software. Some critical applications are also illustrated.

They are low-cost and equipped with a huge array of GPIO (general purpose input output), which can be used to take readings from sensors and control external devices. The active development community and open-source nature also make them ideal choices for many applications. They can be integrated with the accelerator control system and make more devices 'intelligent' via an economical way. It will be helpful to improve the efficiency of the accelerator. The details of the applications in SSRF and SXFEL control system will be reported in this paper.

The Rare Isotope Science Project (RISP) Control System is comprised of ethernet-based devices and equipment. Control system is based on Experimental Physics and Industrial Control System (EPICS) Framework, known as a distributed control system through network. So, we need a way for integrating ethernet-based devices into EPICS Framework. Most of these devices support Simple Network Management Protocol (SNMP). SNMP is based on the manager and agent model and it is similar to EPICS Channel Access (CA) protocol. Therefore, SNMP helps to develop a unified network-based control system with EPICS. In this paper, we will show the network device monitoring system RAON customized SNMP integration into EPICS.

RISP control system uses the EPICS real time distributed control system, which is software framework for stable operation of the accelerator. The output signal from all machines and devices must be archived by EPICS framework, and optimized signal archiver system is needed for each accelerator facility. Signal archiver method using the EPICS framework has three significant ways. First is the classic channel archiver using the file base method and the second is the RDB archiver using the relational database. But classic channel archiver has a problem that the index file containing information of data block corresponding PV data mismatch with real data. Also, there is a problem in the performance of file I/O in RDB archiver. SLAC has developed archiver appliance utility to resolve these problems, and the usage of archiver appliance in EPICS community has gradually increased. RISP choose the archiver appliance to also signal archiver solution. However, archiver appliance is not optimized for our RISP heavy-ion accelerator control system. Thus, we will develop the customized signal archiver system for RISP heavy-ion accelerator control system.

The goal of the MYRRHA project is to demonstrate the technical feasibility of transmutation in a 100 MWth Accelerator Driven System by building a new flexible irradiation complex in Mol (Belgium). The MYRRHA facility requires a 600 MeV linear accelerator delivering a maximum proton flux of 4 mA in continuous operation, with an additional requirement for exceptional reliability. The control system of the future MYRRHA linac will have an essential role to play in this extreme reliability scenario. On the one hand the intrinsic reliability of the entire control system must be ensured. On the other hand control system will have to take up very high level duties of complex decision taking. This paper summarizes the ongoing developments for the concept design of such a control system. The related experimental activities performed and planned around the MYRRHA injector platform (ECR ion source + LEBT + RFQ) will also be described.

The SPEAR3 accelerator uses a Single Photon Time-Correlated Counting (TCSPC) system to accurately measure the time profile of electron bunches circulating in the storage ring. The detection hardware uses the PicoHarp 300 TCSPC processor module initially equipped with an available Hamamatsu H7360-01 photon counting head. The H7360-01 was later replaced with a PicoQuant Hybrid-06 PMA to decrease single-photon arrival time jitter. At the same time we adopted an EPICS-based TCSPC software package developed at DIAMOND for robust data acquisition and display. In this paper we report on recent beam profile measurements and upgrades to the data acquisition software system including installation of a local EPICS IOC for real-time access to the bunch profile from SLAC's centralized Accelerator Control Room (ACR). High-level operator interface and monitoring applications developed in Python are discussed.
