	X. Pang, S.A. Baily, L. Rybarcyk LANL, Los Alamos, New Mexico, USA
	Funding: U.S. Dept. of Energy, NNSA under contract DE-AC52-06NA25396. The LANSCE accelerator complex is a multi-beam facility that provides high-intensity H⁺ and H⁻ particle beams for a variety of user programs. At the heart of the facility is a room temperature linac that is comprised of a 100-MeV drift tube linac and an 800-MeV coupled cavity linac. During beam operations, linac parameters are adjusted to maintain minimal beam spill, but without detailed knowledge of the beam distribution. A more desirable situation would be one where knowledge of the beam distribution along the linac is available to aid in the optimization of the linac operation and beam performance. We are presently developing a high performance simulator that will provide valuable information about the beam distribution in pseudo real-time during linac operations. The heart of the simulator is based upon the multiparticle beam dynamics code PARMILA, but implemented in C++ using NVIDIA’s CUDA technology for Graphics Processing unit (GPU) hardware. Linac operating set points will be provided by the EPICS control system so that changes are tracked and the simulation results updated automatically. Details regarding the approach, benefits and performance will be presented.

	A new design for the Beam Position Monitors (BPMs) diagnostics of ESS-Bilbao, consisting of a whole block of stripline sensors, has been designed and manufactured. The design is based on travelling wave principles to detect the position of the beam in the vacuum chamber. The length of the stripline is 200 mm and the coverage angle is 0.952 rad. The position of the internal tube simulating the beam can be changed with respect to the outer tube within a range of 20 mm approximately for both X and Y axis, with a resolution less than 10 μm. The characteristics of the block with and without beam are measured and evaluated at frequencies of 175 and 352 MHz, using the electronics system developed for the BPM capacitive pick-ups. This electronics system is divided in an Analog Front-End (AFE) unit, where the signals are conditioned and converted to baseband, and a Digital Unit (DU) to sample them and calculate the position and phase of the beam. In this contribution, the performed tests will be fully described and the results also discussed.

	There are seven stripline beam position monitor (BPM) installed in TLS booster to storage ring transport line. In order to provide the BPM system with better performance and functionalities, the latest generation BPM electronics Libera SinglePass had been adopted in TLS transport line for these stripline BPM. One unit had been tested in early 2011 and delivered the reliable and satisfactory results therefore extra six units had been purchased later. Currently, all of the new 7 units have replaced the past BPM electronics. The application had also been continuously developed. On the other hand, it is expected that the upgrade could enhance diagnostic functionalities for the related injection study. In this report, the injection stability and efficiency had been investigated.

	TPS (Taiwan Photon Source) is a 3 GeV synchrotron light source which is being in construction at NSRRC. The orbit measurement and control must be precise much than before in the TPS. New BPM electronic design with the latest generation FPGA and new mechanical form factor to enhance functionality of current generation products will be employed for the TPS. The prototype BPM electronics is testing in the TLS. These testing experiences will be applied in the TPS BPM electronic and software modification. To achieve the stringent orbit stability goal of the TPS, orbit feedback system is designed to eliminate beam motions due to various perturbation sources. The new orbit feedback system is merged to BPM electric system. This design will be enhanced to hardware reliability and fast data exchange performance. The design and implementation plan of the BPM system and the orbit feedback system are summarized in this report.

Kirkman Cockcroft Institute, Warrington, Cheshire, United Kingdom
	The NS-FFAG electron model ‘EMMA’ and its Injection and Extraction Lines are equipped with a total of 53 EPICS VME BPMs. In the BPMs, each opposite button signal pair is time-domain-multiplexed into one channel as a pulse doublet. The recording of turn-by-turn data into the BPM memory is triggered by the bunch itself on each of its passages. For each accelerating cycle, the BPMs deliver a snapshot of a turn-by-turn trajectory measured in each of 42 cells. Additional BPMs (two pairs) are used to obtain a Poincare map. We describe the EPICS architecture, and a set of Python data processing algorithms that are used to automatically set a BPM intensity range, to eliminate an error due to tails of the doublet pulses, to calculate the bunch charge and position, and, for a set of injections, to find the BPM resolution. We use three types of button pickup mappings* that allow: to eliminate bunch charge signal dependence on offset, to get a linear offset response, and to eliminate ‘quadrupole’ signal dependence on offset as well (which is used in resolution calculation). We present beam measurement results collected in 2011 runs. * A. Kalinin et al., Proc. of IPAC’10, MOPE068, p. 1134, (2010. ** I. Kirkman, these proceedings.

	J.D. Gilpatrick, M.E. Gruchalla, D. Martinez, C. Pillai, S. Rodriguez Esparza, J.D. Sedillo, B.G. Smith LANL, Los Alamos, New Mexico, USA
	Funding: Work supported by the U.S. Department of Energy. The Los Alamos Neutron Science Center (LANSCE) is replacing beam profile measurement systems, commonly known as Wire Scanners (WS’s). Using the principal of secondary electron emission, the WS measurement system moves a wire or fiber across an impinging particle beam, sampling a projected multi-bin distribution. Because existing WS actuators and electronic components are either no longer manufactured or home-built with antiquated parts, a new wire scanner beam profile measurement is being designed, fabricated, and tested. The goals for these new wire scanner include using off-the-shelf components while eliminating antiquated components, providing quick operation while allowing for easy maintainability, and tolerating external radioactivation. The WS measurement system consists of beam line actuators, a simple cable plant, an electronics processor chassis, and software located both in the electronics chassis (National Instruments LabVIEW) and in the Central Control Room (EPICS-based software). This WS measurement system will measure the more common H⁻ and H⁺ LANSCE-facility beams and will also measure less common beams. This paper describes these WS measurement systems.

TUPPC048	Online Physics Model Platform	controls, lattice, simulation, monitoring	1275
	P. Chu, Y. Zhang FRIB, East Lansing, Michigan, USA C. Benatti, V. Vuppala NSCL, East Lansing, Michigan, USA D. Dohan, G. Shen BNL, Upton, Long Island, New York, USA J. Wu SLAC, Menlo Park, California, USA
	Funding: This material is based upon work supported by the U.S. Department of Energy Office of Science under Cooperative Agreement DE-SC0000661 For a complex accelerator such as the Facility for Rare Isotope Beams (FRIB), a transfer matrix based online model might not be sufficient for the entire machine. On the other hand, if introducing another modelling tools, physics applications have to be rewritten for all modelling tools. A platform which can host multiple modelling tools would be ideal for such scenario. Furthermore, the model platform along with infrastructure support can be used not only for online applications but also for offline purposes with multi-particle tracking simulation. In order to achieve such a platform, a set of common physics data structures has to be set. XAL's accelerator hierarchy based data structure is a good choice as the common structure for various models. Application Programming Interface (API) for physics applications should also be defined within a model data provider. A preliminary platform design and prototype is discussed.

	C.F. Eckman, A. Andrews, Y. Kim, S. Setiniyaz, D.P. Wells IAC, Pocatello, IDAHO, USA A.W. Hunt ISU, Pocatello, Idaho, USA
	At the Idaho Accelerator Center (IAC) of Idaho State University, we have been operating fifteen low energy accelerators. To optimize those accelerators properly, we have to measure the transverse beam emittance. To measure the transverse beam emittance of an S-band linear accelerator with the quadrupole scan technique, we installed an Optical Transition Radiation (OTR) screen and a digital CCD camera in the bealime of the accelerator. From the images of the digital CCD camera, the transverse beam profile on the OTR screen can be acquired. To extract the transverse beam size and to estimate the transverse emittance, we have developed a MATLAB program. This paper describe the details of the MATLAB program and performance of our MATLAB based emittance measurement tool.

	As of 2011, fabrication and testing of main linac 7-cell cavities has begun for Cornell's Energy Recovery Linac prototype project. To standardize the testing process, minimize errors and allow for quick and precise measurements of these cavities, a suite of MatLab programs has been written to automate cavity tests. The programs allow measuring the quality factor versus temperature, and quality factor vs. accelerating gradient, and allow extracting material properties such as RRR and residual resistance. They are compatible with EPICS input/output controllers or standalone computers. Finally, the program can measure continuous Q vs E curves from a single high field decay curve, and can perform temperature mapping and quench localization from oscillating superleak transducer data.

	Funding: SNS is managed by UT-Battelle, LLC, under contract DE-AC05-00OR22725 for the U.S. Department of Energy. A four-way waveguide RF power distribution system for testing the SNS multi-cavity cryomodule to investigate the collective behavior has been developed. A single klystron operating at 805MHz in 60Hz 8% duty cycle powers the 4-way waveguide splitter to deliver up to 600 kW to Individual cavities. Each cavity is fed through a waveguide vector modulator at each splitter output with magnitude and phase control. Waveguide vector modulator consists of two quadrature hybrids and two motorized waveguide phase shifters. The phase shifters and the assembled waveguide vector modulators were individually tested and characterized for low power and high pulsed RF power in the SNS RF test facility. Precise calibrations of magnitude and phase are done to generate the look up tables (LUTs) to provide operation references during the cryomodule test. An IQ demodulator board was developed and utilized to generate 2-port magnitude and phase LUTs. PLC units were developed for mechanical control of the phase shifters. Labview software was programmed for the measurements and the system operation. LUT based operation algorithm was implemented into EPICS control for the cryomodule test stand.

	The timing system of the Taiwan Photon Source is used to distribute trigger signals and synchronously clocks to all the equipment of the machine which need them. The timing system basically works by sending event codes from one event generator (EVG) through tree structured, bidirectional optical fiber network to many event receivers. To accommodate various operation and injection scenarios of the TPS storage ring and booster synchrotron and LINAC, timing sequencer design and control is crucial. The sequencer (event code) is stored at sequence RAM of the EVG module. In order to manage sequence RAM of EVG, the timing sequence control is considered to use Matlab scripts embedded in the timing master EPICS IOC. The timing sequencer design will be summarized in this paper.

	N.P. Di Monte, R.I. Farnsworth, A.J. Scaminaci ANL, Argonne, USA
	With the success of the transverse feedback system at the Advanced Photon Source (APS), an upgrade to this system is being developed. The current system is operating at a third of the storage ring bunch capacity, or 324 of the available 1296 bunches. This upgrade will allow the sampling of all 1296 bunches and make corrections for all selected bunches in a single storage ring turn. To facilitate this upgrade, a new analog I/O board capable of 352-MHz operation is being developed along with a P0 bunch cleaning circuit. The clock cleaning circuit is also needed for the high speed analog output circuit, which is transmitted about 200 m to a separate DAC unit in real time. This remote DAC will have its transceiver data rate triple from 2.3 Gb to about 7 Gb on a fiber optic link. This paper will discuss some of the challenges in reducing the clock jitter from the system P0 bunch clock along with the necessary FPGA hardware upgrades and algorithm changes, all of which are required for the success of this upgrade.

	The availability of brighter synchrotorn X-ray sources enable more complex experiments, such as 2D or 3D X-mapping. All the electrical signals generated in scmiconductive detectors are then processed and analysed by fast digital pulse processors (DPP). The poster presents the state of the art DPP currently in development by Instrumentation Technologies . We will discuss the signal transformation and processing from the detector preamplifier output to the final result: energy histogram and time stamped list mode. The signal processing chain starts with signal conditioning of the analog input signal. After the ADCs transformation, all the signal processing in the digital domain is done in FPGA. To each measured pulse a time-stamp is applied. Libera BASE FDK enables customer specific algorithms to be included in the FPGA.

	Funding: ESS Bilbao Consortium Wired connections are very often irreplaceable in large scientific facilities due to performance and reliability issues. However, those communication links suffer from several disadvantages, such as lack of flexibility during deployment or reconfiguration and deterioration of wires and physical connectors. The goal of the present work is to introduce wireless EPICS sub-networks in a standard general wired EPICS system. This involves the study and selection of a proper wireless technology, architecture, communication strategy and security policy. To ensure the validity of the proposed approach, a thorough study of the results related parameters, such as throughput, security, repeatability and stability of the overall system is needed. Once those are considered, the next step is to decide where and when the replacement of physical connections with Wireless communication systems is suitable. The aim is to eliminate as many wires as possible without decreasing the reliability, security and performance of the current EPICS control network.

	The TLS (Taiwan Light Source) is a third generation of synchrotron light source, and it has been operated since 1993. The TLS control system was developed and implemented by ourselves. The control system of our new project (TPS, Taiwan Photon Source) is developed and based upon the EPICS framework. To earn more experiences on the EPICS usage, some of the TLS newly installed subsystem run EPICS directly. For example, BPM system, bunch-by-bunch feedback system, remote oscilloscope waveform access and so on adapt the EPICS interface to control and monitor. The EDM and Matlab (with LabCA) toolkits are used as EPICS graphical user interface, and it is also operated at the TLS control consoles environment normally. The archive system transaction between the TLS control system format and EPICS PVs (Process Variables) has been implemented for user access with the existing archive viewer. The efforts will be described at this report.

	At the Idaho Accelerator Center (IAC) of Idaho State University, we have been operating 15 low energy accelerators for nuclear physics applications and medical isotope production. But those accelerator do not have good computer based system to control the various accelerator components remotely. To obtain stable accelerator operations with a good reproducibility, we adapted the EPICS accelerator control system. After developing one full set of the EPICS accelerator control system for various components, we will apply the same EPICS control system for all other operating accelerators at the IAC. Since January 2011, we have been developing an EPICS control system for a 16 MeV S-band linac by collaborating with SLAC control group. In this paper, we describe our first EPICS accelerator control system to control magnet power supplies of the S-band linac at the IAC.

The LANSCE accelerator complex is a multi-beam facility that provides high-intensity H⁺ and H⁻ particle beams for a variety of user programs. At the heart of the facility is a room temperature linac that is comprised of a 100-MeV drift tube linac and an 800-MeV coupled cavity linac. During beam operations, linac parameters are adjusted to maintain minimal beam spill, but without detailed knowledge of the beam distribution. A more desirable situation would be one where knowledge of the beam distribution along the linac is available to aid in the optimization of the linac operation and beam performance. We are presently developing a high performance simulator that will provide valuable information about the beam distribution in pseudo real-time during linac operations. The heart of the simulator is based upon the multiparticle beam dynamics code PARMILA, but implemented in C++ using NVIDIA’s CUDA technology for Graphics Processing unit (GPU) hardware. Linac operating set points will be provided by the EPICS control system so that changes are tracked and the simulation results updated automatically. Details regarding the approach, benefits and performance will be presented.

A new design for the Beam Position Monitors (BPMs) diagnostics of ESS-Bilbao, consisting of a whole block of stripline sensors, has been designed and manufactured. The design is based on travelling wave principles to detect the position of the beam in the vacuum chamber. The length of the stripline is 200 mm and the coverage angle is 0.952 rad. The position of the internal tube simulating the beam can be changed with respect to the outer tube within a range of 20 mm approximately for both X and Y axis, with a resolution less than 10 μm. The characteristics of the block with and without beam are measured and evaluated at frequencies of 175 and 352 MHz, using the electronics system developed for the BPM capacitive pick-ups. This electronics system is divided in an Analog Front-End (AFE) unit, where the signals are conditioned and converted to baseband, and a Digital Unit (DU) to sample them and calculate the position and phase of the beam. In this contribution, the performed tests will be fully described and the results also discussed.

There are seven stripline beam position monitor (BPM) installed in TLS booster to storage ring transport line. In order to provide the BPM system with better performance and functionalities, the latest generation BPM electronics Libera SinglePass had been adopted in TLS transport line for these stripline BPM. One unit had been tested in early 2011 and delivered the reliable and satisfactory results therefore extra six units had been purchased later. Currently, all of the new 7 units have replaced the past BPM electronics. The application had also been continuously developed. On the other hand, it is expected that the upgrade could enhance diagnostic functionalities for the related injection study. In this report, the injection stability and efficiency had been investigated.

TPS (Taiwan Photon Source) is a 3 GeV synchrotron light source which is being in construction at NSRRC. The orbit measurement and control must be precise much than before in the TPS. New BPM electronic design with the latest generation FPGA and new mechanical form factor to enhance functionality of current generation products will be employed for the TPS. The prototype BPM electronics is testing in the TLS. These testing experiences will be applied in the TPS BPM electronic and software modification. To achieve the stringent orbit stability goal of the TPS, orbit feedback system is designed to eliminate beam motions due to various perturbation sources. The new orbit feedback system is merged to BPM electric system. This design will be enhanced to hardware reliability and fast data exchange performance.

The NS-FFAG electron model ‘EMMA’ and its Injection and Extraction Lines are equipped with a total of 53 EPICS VME BPMs*. In the BPMs, each opposite button signal pair is time-domain-multiplexed into one channel as a pulse doublet. The recording of turn-by-turn data into the BPM memory is triggered by the bunch itself on each of its passages. For each accelerating cycle, the BPMs deliver a snapshot of a turn-by-turn trajectory measured in each of 42 cells. Additional BPMs (two pairs) are used to obtain a Poincare map. We describe the EPICS architecture, and a set of Python data processing algorithms that are used to automatically set a BPM intensity range, to eliminate an error due to tails of the doublet pulses, to calculate the bunch charge and position, and, for a set of injections, to find the BPM resolution. We use three types of button pickup mappings** that allow: to eliminate bunch charge signal dependence on offset, to get a linear offset response, and to eliminate ‘quadrupole’ signal dependence on offset as well (which is used in resolution calculation). We present beam measurement results collected in 2011 runs.

The Los Alamos Neutron Science Center (LANSCE) is replacing beam profile measurement systems, commonly known as Wire Scanners (WS’s). Using the principal of secondary electron emission, the WS measurement system moves a wire or fiber across an impinging particle beam, sampling a projected multi-bin distribution. Because existing WS actuators and electronic components are either no longer manufactured or home-built with antiquated parts, a new wire scanner beam profile measurement is being designed, fabricated, and tested. The goals for these new wire scanner include using off-the-shelf components while eliminating antiquated components, providing quick operation while allowing for easy maintainability, and tolerating external radioactivation. The WS measurement system consists of beam line actuators, a simple cable plant, an electronics processor chassis, and software located both in the electronics chassis (National Instruments LabVIEW) and in the Central Control Room (EPICS-based software). This WS measurement system will measure the more common H⁻ and H⁺ LANSCE-facility beams and will also measure less common beams. This paper describes these WS measurement systems.

For a complex accelerator such as the Facility for Rare Isotope Beams (FRIB), a transfer matrix based online model might not be sufficient for the entire machine. On the other hand, if introducing another modelling tools, physics applications have to be rewritten for all modelling tools. A platform which can host multiple modelling tools would be ideal for such scenario. Furthermore, the model platform along with infrastructure support can be used not only for online applications but also for offline purposes with multi-particle tracking simulation. In order to achieve such a platform, a set of common physics data structures has to be set. XAL's accelerator hierarchy based data structure is a good choice as the common structure for various models. Application Programming Interface (API) for physics applications should also be defined within a model data provider. A preliminary platform design and prototype is discussed.

At the Idaho Accelerator Center (IAC) of Idaho State University, we have been operating fifteen low energy accelerators. To optimize those accelerators properly, we have to measure the transverse beam emittance. To measure the transverse beam emittance of an S-band linear accelerator with the quadrupole scan technique, we installed an Optical Transition Radiation (OTR) screen and a digital CCD camera in the bealime of the accelerator. From the images of the digital CCD camera, the transverse beam profile on the OTR screen can be acquired. To extract the transverse beam size and to estimate the transverse emittance, we have developed a MATLAB program. This paper describe the details of the MATLAB program and performance of our MATLAB based emittance measurement tool.

As of 2011, fabrication and testing of main linac 7-cell cavities has begun for Cornell's Energy Recovery Linac prototype project. To standardize the testing process, minimize errors and allow for quick and precise measurements of these cavities, a suite of MatLab programs has been written to automate cavity tests. The programs allow measuring the quality factor versus temperature, and quality factor vs. accelerating gradient, and allow extracting material properties such as RRR and residual resistance. They are compatible with EPICS input/output controllers or standalone computers. Finally, the program can measure continuous Q vs E curves from a single high field decay curve, and can perform temperature mapping and quench localization from oscillating superleak transducer data.

A four-way waveguide RF power distribution system for testing the SNS multi-cavity cryomodule to investigate the collective behavior has been developed. A single klystron operating at 805MHz in 60Hz 8% duty cycle powers the 4-way waveguide splitter to deliver up to 600 kW to Individual cavities. Each cavity is fed through a waveguide vector modulator at each splitter output with magnitude and phase control. Waveguide vector modulator consists of two quadrature hybrids and two motorized waveguide phase shifters. The phase shifters and the assembled waveguide vector modulators were individually tested and characterized for low power and high pulsed RF power in the SNS RF test facility. Precise calibrations of magnitude and phase are done to generate the look up tables (LUTs) to provide operation references during the cryomodule test. An IQ demodulator board was developed and utilized to generate 2-port magnitude and phase LUTs. PLC units were developed for mechanical control of the phase shifters. Labview software was programmed for the measurements and the system operation. LUT based operation algorithm was implemented into EPICS control for the cryomodule test stand.

The timing system of the Taiwan Photon Source is used to distribute trigger signals and synchronously clocks to all the equipment of the machine which need them. The timing system basically works by sending event codes from one event generator (EVG) through tree structured, bidirectional optical fiber network to many event receivers. To accommodate various operation and injection scenarios of the TPS storage ring and booster synchrotron and LINAC, timing sequencer design and control is crucial. The sequencer (event code) is stored at sequence RAM of the EVG module. In order to manage sequence RAM of EVG, the timing sequence control is considered to use Matlab scripts embedded in the timing master EPICS IOC. The timing sequencer design will be summarized in this paper.

With the success of the transverse feedback system at the Advanced Photon Source (APS), an upgrade to this system is being developed. The current system is operating at a third of the storage ring bunch capacity, or 324 of the available 1296 bunches. This upgrade will allow the sampling of all 1296 bunches and make corrections for all selected bunches in a single storage ring turn. To facilitate this upgrade, a new analog I/O board capable of 352-MHz operation is being developed along with a P0 bunch cleaning circuit. The clock cleaning circuit is also needed for the high speed analog output circuit, which is transmitted about 200 m to a separate DAC unit in real time. This remote DAC will have its transceiver data rate triple from 2.3 Gb to about 7 Gb on a fiber optic link. This paper will discuss some of the challenges in reducing the clock jitter from the system P0 bunch clock along with the necessary FPGA hardware upgrades and algorithm changes, all of which are required for the success of this upgrade.

The availability of brighter synchrotorn X-ray sources enable more complex experiments, such as 2D or 3D X-mapping. All the electrical signals generated in scmiconductive detectors are then processed and analysed by fast digital pulse processors (DPP). The poster presents the state of the art DPP currently in development by Instrumentation Technologies . We will discuss the signal transformation and processing from the detector preamplifier output to the final result: energy histogram and time stamped list mode. The signal processing chain starts with signal conditioning of the analog input signal. After the ADCs transformation, all the signal processing in the digital domain is done in FPGA. To each measured pulse a time-stamp is applied. Libera BASE FDK enables customer specific algorithms to be included in the FPGA.

Wired connections are very often irreplaceable in large scientific facilities due to performance and reliability issues. However, those communication links suffer from several disadvantages, such as lack of flexibility during deployment or reconfiguration and deterioration of wires and physical connectors. The goal of the present work is to introduce wireless EPICS sub-networks in a standard general wired EPICS system. This involves the study and selection of a proper wireless technology, architecture, communication strategy and security policy. To ensure the validity of the proposed approach, a thorough study of the results related parameters, such as throughput, security, repeatability and stability of the overall system is needed. Once those are considered, the next step is to decide where and when the replacement of physical connections with Wireless communication systems is suitable. The aim is to eliminate as many wires as possible without decreasing the reliability, security and performance of the current EPICS control network.

The TLS (Taiwan Light Source) is a third generation of synchrotron light source, and it has been operated since 1993. The TLS control system was developed and implemented by ourselves. The control system of our new project (TPS, Taiwan Photon Source) is developed and based upon the EPICS framework. To earn more experiences on the EPICS usage, some of the TLS newly installed subsystem run EPICS directly. For example, BPM system, bunch-by-bunch feedback system, remote oscilloscope waveform access and so on adapt the EPICS interface to control and monitor. The EDM and Matlab (with LabCA) toolkits are used as EPICS graphical user interface, and it is also operated at the TLS control consoles environment normally. The archive system transaction between the TLS control system format and EPICS PVs (Process Variables) has been implemented for user access with the existing archive viewer. The efforts will be described at this report.

Insertion device (ID) is a crucial component in third-generation synchrotron light sources, which can produces highly-brilliant, forward-directed and quasi-monochromatic radiation over a broad energy range for various experiments. In the phase I of the Taiwan Photon Source (TPS) project, ten insertion devices (IDs) will be planned, constructed, and installed for the first seven beamlines. The control system for all the IDs is based on the EPICS architecture. The main control components include the motor with encoder for gap adjustment, trim coil power supply for corrector magnets, temperature sensor for ID environmental monitoring and baking (only for In-Vacuum Undulator), and interlock system (limit switches, tilt sensor) for safety. The progress of the controls plan will be summarized in this report.

The Facility for Rare Isotope Beams (FRIB) is setting up its high-level application software architecture. The architecture is based on Service Oriented Architecture, and consists of back-end data storage, client/service infrastructure, control system connectivity, supporting libraries and front-end Graphical User Interface (GUI). The architecture provides online models of FRIB as a service and allows for storage of both structured and non-structured data. The model for structured data is implemented using the Integrated Relational Model of Installed Systems (IRMIS). The GUI is based on Control System Studio (CSS) framework. Libraries, service, data access and GUI tools will be available as Application Programming Interface (API) or plug-ins. The infrastructure and technologies chosen here will utilize the robustness and performance for applications, as well as support quick prototyping for physicists. This paper describes FRIB’s high-level application software architecture and some of the current prototypes.

At the Idaho Accelerator Center (IAC) of Idaho State University, we have been operating 15 low energy accelerators for nuclear physics applications and medical isotope production. But those accelerator do not have good computer based system to control the various accelerator components remotely. To obtain stable accelerator operations with a good reproducibility, we adapted the EPICS accelerator control system. After developing one full set of the EPICS accelerator control system for various components, we will apply the same EPICS control system for all other operating accelerators at the IAC. Since January 2011, we have been developing an EPICS control system for a 16 MeV S-band linac by collaborating with SLAC control group. In this paper, we describe our first EPICS accelerator control system to control magnet power supplies of the S-band linac at the IAC.

The 100MeV proton linear accelerator of the Proton Engineering Frontier Project (PEFP) has been developed and will be installed in Gyeong-ju site. After the installation, the beam commissioning of the 100MeV linac will be performed in 2012. A machine protection system (MPS) to shut off beam and to protect the 100MeV machine has been designed. Hardwares for an RF interlock, a modulator interlock, beam loss monitors, fast closing valves for vacuum window faults and so on have been manufactured and tested. With a hard-wired protection for a fast interlock, beam should be shut off within a few μs from the faults. The operator interface for MPS has been also designed to monitor and reset the faults easily. The details of the MPS design for the 100MeV machine are presented.
