MOC3O04	System Identification and Robust Control for the LNLS UVX Fast Orbit Feedback	controls, feedback, network, vacuum	30
	D.O. Tavares LNLS, Campinas, Brazil D.R. Grossi Sao Paulo University, São Carlos Campus, São Carlos, Brazil
	This paper describes the optimization work carried out to improve the performance of the LNLS UVX fast orbit feedback system. Black-box system identification techniques were applied to model the dynamic behavior of BPM electronics, orbit correctors, communication networks and vacuum chamber eddy currents. Due to the heterogeneity on the dynamic responses among several units of those subsystems, as well as variations on the static response matrix due to accelerator optics changes during operation, robust control techniques were employed to achieve appropriate closed-loop performance and robustness.

MOPGF001	Use Interrupt Driven Mode to Redesign an IOC for Digital Power Supply at SSC-LINAC	controls, linac, Ethernet, EPICS	98
	S. An, K. Gu, X.J. Liu, J.Q. Wu, W. Zhang IMP/CAS, Lanzhou, People's Republic of China
	SSC-LINAC control system is based on EPICS architecture. The sub control system of digital power supplies is a kind of IOC send and receive custom command via Ethernet and TCP/IP protocol. The old IOC is designed to use period scan mode IOC, and there are so many digital power supplies, that we can't make sure every connect condition of digital power supply is fine. IOC must wait a long time if one of them can't connect correctly and other digital power supply's PV may also be blocked. An IOC that uses interrupt driven mode to avoid the shortcoming was designed. This will be described in this paper.

MOPGF002	Magnet Corrector Power Supply Controller for LCLS-I	controls, interface, feedback, EPICS	100
	S. Babel, B. Lam, K. Luchini, J.J. Olsen, T. Straumann, E. Williams, C. Yee SLAC, Menlo Park, California, USA
	The MCOR-12[Magnet Corrector] is a 16-channel modular architecture, precision magnet driver, capable of providing bipolar output currents in the range from 12A to +12A. A single, unregulated bulk power supply provides the main DC power for the entire crate. Currently the MCORs have a 1000ppm regulation on the B-field. The MCOR controller card upgrades, existing LCLS-I and future LCLS-II needed, controls for Magnet Corrector Power Supplies. The project shifts the existing functionality of the VME based DAC and SAM and an Allen Bradley PLC into a new slot-0 card residing in the MCOR chassis. Elimination of the VME crate and the PLC will free up rack space to be used in future. The new interface card has a long term stability of 100 ppm and monitors ground fault currents and various other interlocks for the MCOR power supplies. The controller can interface to EPICS Channel Access and Fast Feedback system at SLAC using two Gigabit Ethernet ports and has an FPGA based EVR for getting 'time stamps' from the Event Generator system at SLAC. The EPICS control system along with embedded diagnostic features will allow for enhanced remote control and monitoring of the power supplies. S. Babel, S.

MOPGF023	Update of Power Supply Control System at the SAGA Light Source Storage Ring	controls, storage-ring, PLC, target	137
	Y. Iwasaki, T. Kaneyasu, S. Koda, Y. Takabayashi SAGA, Tosu, Japan
	The update of control system at the SAGA Light Source storage ring power supplies is in progress for improving the ramp-up speed (from 255 MeV to 1.4 GeV) and for easily changing the stored beam energy. By replacing the CPU unit of PLC used for control of the power supplies, the ramp-up time was reduced from 4 to 2 minutes in a test bench prepared for the upgrade system. Currently the allowable beam energy is restricted to some fixed values in the ramp-up operation due to the original specification of the PLC ladder program. To operate storage ring at an arbitrary energy, the algorism used in the PLC program has been improvement. Energy dependent measurements (betatron-tune, beam size, and beam half-lifetime) will be carried out by using the updated control system. The upper layer of the control system using the National Instrument LabVIEW and ActiveXCA was also reconstructed for flexible GUI.

	P.C. Chiu, Y.-S. Cheng, K.T. Hsu, K.H. Hu, C.Y. Liao NSRRC, Hsinchu, Taiwan
	The TPS is a state-of-the-art synchrotron radiation facility featuring ultra-high photon brightness with extremely low emittance. Its Booster has 6 FODO cells which include 7 BD dipoles with 1.6 m long and 2 BH dipoles with 0.8 m long in each cell. After magnetization of stainless steel vacuum chamber of the booster were identified and then dismantled, annealed, and re-installed, the electron beam energy of the Taiwan Photon Source (TPS) in the booster ring has ramped to 3 GeV in a week. The booster tune correction during ramping is one of the main reasons why the booster commissioning progress is so fast. In this paper the summarized the booster tune monitor system will be summarised

MOPGF117	The Control System for Trim-Coil Relay-Selectors in J-PARC MR	controls, EPICS, PLC, operation	353
	K.C. Sato, N. Kamikubota, N. Yamamoto J-PARC, KEK & JAEA, Ibaraki-ken, Japan S. Igarashi KEK, Ibaraki, Japan S.Y. Yoshida Kanto Information Service (KIS), Accelerator Group, Ibaraki, Japan
	In J-PARC main ring, each of the main magnets (Dipole, Quadrupole, and Sextupole) has a trim-coil. The basic aim of trim-coil is to correct small deviation of each magnetic field. In addition, we have used them for other purposes, for example: (1) in Beam-Based-Alingnment studies, (2) as flux monitors, and (3) to make a short-circuit to reduce ripples of magnetic field. At a moment, trim-coils can be used for only one purpose. Relay-switches were introduced to change trim-coil connection to a device, which corresponds to the selected purpose. When the purpose is switched, 1,200 on-site relays have to be changed manually, distributed in three buildings. Thus, a control system for trim-coil relay-selectors was developed in winter, 2014-2015. EPICS tools and environment are used to develop the system. The system comprises PLC I/O modules with controller running EPICS on Linux. The system will be in operation after March, 2015. By using the system, a much easier switching of relay-switches than before, is expected.

MOPGF135	Upgrade of the Trigger Synchronisation and Distribution System of the Beam Dumping System of the Large Hadron Collider	operation, dumping, controls, hardware	397
	N. Magnin, A. Antoine, E. Carlier, V. Chareyre, S. Gabourin, A. Patsouli, N. Voumard CERN, Geneva, Switzerland
	Various upgrades were performed on the Large Hadron Collider (LHC) Beam Dumping System (LBDS) during Long Shutdown 1 (LS1) at CERN, in particular to the Trigger Synchronisation and Distribution System (TSDS): A redundant direct connection from the LHC Beam Interlock System to the re-trigger lines of the LBDS was implemented, a fully redundant powering architecture was set up, and new Trigger Synchronisation Unit cards were deployed over two separate crates instead of one. These hardware changes implied the adaptation of the State Control and Surveillance System and an improvement of the monitoring and diagnosis systems, like the various Internal Post Operation Check (IPOC) systems that ensure that, after every beam dump event, the LBDS worked as expected and is 'as good as new' for the next LHC beam. This paper summarises the changes performed on the TSDS during LS1, highlights the upgrade of the IPOC systems and presents the problems encountered during the commissioning of TSDS before the LHC Run II.

	There were more than 2500 magnet power supplies for KEKB storage rings and injection beam transport lines. For the remote control of such a large number of power supplies, the Power Supply Interface Controller Module (PSICM), which is plugged into each power supply, was developed. It has a microprocessor, ARCNET interface, trigger signal input interface, and parallel interface to the power supply. The PSICM is not only an interface card but also controls synchronous operation of the multiple power supplies with an arbitrary tracking curve. For SuperKEKB we have developed the upgraded version of the PSICM. It has the fully backward compatible interface to the power supply. The enhanced features includes high speed ARCNET communication and redundant trigger signals. Towards the phase 1 commissioning of SuperKEKB, the construction of the magnet control system is ongoing. First mass production of 1000 PSICMs has been completed and their installation is in progress. The construction status of the magnet control system is presented in this paper.

The intermediate layer is a data processing and transmission. Device control layer performs data output of the power supply. We use ARM + DSP controller designed by ourselves for controlling the power supply output. At the same time, we have adopted the FPGA controller designed for timing for power supply control in order to meet the requirements of accelerator synchronized with the output of the power supply.

There were more than 2500 magnet power supplies for KEKB storage rings and injection beam transport lines. For the remote control of such a large number of power supplies, the Power Supply Interface Controller Module (PSICM), which is plugged into each power supply, was developed. It has a microprocessor, ARCNET interface, trigger signal input interface, and parallel interface to the power supply. The PSICM is not only an interface card but also controls synchronous operation of the multiple power supplies with an arbitrary tracking curve. For SuperKEKB we have developed the upgraded version of the PSICM. It has the fully backward compatible interface to the power supply. The enhanced features includes high speed ARCNET communication and redundant trigger signals. Towards the phase 1 commissioning of SuperKEKB, the construction of the magnet control system is ongoing. First mass production of 1000 PSICMs has been completed and their installation is in progress. The construction status of the magnet control system is presented in this paper.

Control system for the Taiwan Photon Source (TPS) has been completed in 2014. Commissioning of the accelerator system is in proceeding. Electron beam were stored at the storage ring and emit first light in December 31, 2014. TPS control system adopts EPICS toolkits as its frameworks. The subsystems control interfaces include event based timing system, Ethernet based power supply control, corrector power supply control, PLC-based pulse magnet power supply control and machine protection system, insertion devices motion control system, various diagnostics related control environment, and etc. The standard hardware components had been installed and integrated, and the various IOCs (Input Output Controller) had been implemented as various subsystems control platforms. Low level and high level hardware and software are tested intensively in 2014 and final revise to prepare for routine operation is under way. Efforts will be summarized at this paper.
