	Funding: Work supported in part by the Italian Ministry of University and Research under grants FIRB-RBAP045JF2 and FIRB-RBAP06AWK3 The control system architecture of modern experimental physics facilities needs to meet the requirements of the ever increasing complexity of the controlled devices. Whenever feasible, moving from a distributed architecture based on powerful but complex and expensive computers to an even more pervasive approach based on simple and cheap embedded systems, allows shifting the knowledge close to the devices. The BeagleBone computer, being capable of running a full featured operating system such as GNU/Linux, integrates effectively into the existing control systems and allows executing complex control functions with the required flexibility. The paper discusses the choice of the BeagleBone as embedded platform and reports some examples of control applications recently developed for the ELETTRA and FERMI@Elettra light sources.

MOPPC034	Control System Hardware Upgrade	controls, hardware, interface, software	151
	G. Janser, G. Dzieglewski, W. Hugentobler, F. Kreis PSI, Villigen PSI, Switzerland
	The Paul Scherrer Institute builds, runs and maintains several particle accelerators. The proton accelerator HIPA, the oldest facility, was mostly equipped with CAMAC components until a few years ago. In several phases CAMAC was replaced by VME hardware and involved about 60 VME crates with 500 cards controlling a few hundred power supplies, motors, and digital as well as analog input/output channels. To control old analog and new digital power supplies with the same new VME components, an interface, so called Multi-IO, had to be developed. In addition, several other interfaces like accommodating different connectors had to be build. Through a few examples the upgrade of the hardware will be explained.

MOPPC066	Reliability Analysis of the LHC Beam Dumping System Taking into Account the Operational Experience during LHC Run 1	dumping, operation, controls, diagnostics	250
	R. Filippini, E. Carlier, N. Magnin, J.A. Uythoven CERN, Geneva, Switzerland
	The LHC beam dumping system operated reliably during the Run 1 period of the LHC (2009 – 2013). As expected, there were a number of internal failures of the beam dumping system which, because of in-built safety features, resulted in safe removal of the particle beams from the machine. These failures (i.e. "false" beam dumps) have been appointed to the different failure modes and are compared to the predictions made by a reliability model established before the start of LHC operation. A statistically significant difference between model and failure data identifies those beam dumping system components that may have unduly impacted on the LHC availability and safety or might have been out of the scope of the initial model. An updated model of the beam dumping system reliability is presented, taking into account the experimental data presented and the foreseen system changes to be made in the 2013 – 2014 LHC shutdown.

	The Idaho Accelerator Center (IAC) of Idaho State University (ISU) has been operating nine low energy accelerators. Since the beginning of the fall semester of 2012, the ISU Advanced Accelerator and Ultrafast Beam Lab (AAUL) group has been working to develop a new EPICS system to control 47 magnet power supplies for an IAC 44 MeV L-band linear accelerator. Its original control system was fully analog, which had several limitations to get good reproducibility and stability during the accelerator operation. This paper describes our group’s team effort and accomplishment in developing a new EPICS system to control 15 Lambda EMS and 32 TDK-Lambda ZUP power supplies for the IAC L-band linear accelerator. In addition, we also describe several other useful tools such as the save and restore function.

TUPPC089	Upgrade of the Power Supply Interface Controller Module for SuperKEKB	interface, controls, operation, hardware	790
	T.T. Nakamura, A. Akiyama, K. Furukawa, M. Iwasaki, H. Kaji, S. Sasaki KEK, Ibaraki, Japan
	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, we have developed the Power Supply Interface Controller Module (PSICM), which is plugged into each power supply. 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, the upgrade of KEKB, most of the existing power supplies continues while handreds of new power suplies are also installed. Although the PSICMs have worked without serious problem for 12 years, it seems too hard to keep maintenance for the next decade because of the discontinued parts. Thus we have developed the upgraded version of the PSICM. The new PSICM has the fully backward compatible interface to the power supply. The enhanced features are high speed ARCNET communication and redundant trigger signals. The design and the status of the upgraded PSICM are presented.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. For a number of years there has been an increasing desire to adopt a synoptic display suite within BNL accelerator community. Initial interest in the precursors to the modern display suites like MEDM quickly fizzled out as our users found them aesthetically unappealing and cumbersome to use. Subsequent attempts to adopt Control System Studio (CSS) also fell short when work on the abstraction bridge between CSS and our control system stalled and was eventually abandoned. Most recently, we tested the open source version of a synoptic display developed at Fermilab. It, like its previously evaluated predecessors, also seemed rough around the edges, however a few implementation details made it more appealing than every single previously mentioned solution and after a brief evaluation we settled on Synoptic as our display suite of choice. This paper describes this adoption process and goes into details on several key changes and improvements made to the original implementation – a few of which made us rethink how we want to use this tool in the future.

TUCOCA10	Improvements in the T2K Primary Beamline Control System	PLC, controls, EPICS, status	940
	K. Nakayoshi, Y. Fujii, K. Sakashita KEK, Tsukuba, Japan
	T2K is a long-baseline neutrino oscillation experiment in Japan. We report recent improvements in the T2K primary beamline control system. The first improvement is a new interlock system for current fluctuations of the normal-conducting (NC) magnet power supplies. To prevent the intense beam from hitting the beamline equipment due to a current fluctuation in a magnet power supply, we continuously monitor the power supply output current using digital-panel-meters. The second improvement is a new PLC-based control system for the NC magnet power supplies. We will also discuss the actual implementation of these improvements.

	The modernization project of the low-current power supply system of Kurchatov Synchrotron Radiation Source has been designed and is under implementation now. It includes transition to the new power suppliers to feed electron beam orbit correctors and focusing lenses. Multi-level control system, based on CAN/CANopen fieldbus, has been developed for specific accelerator applications, which allows startup and continuous run of hundreds of power supplies together with the other subsystems of the accelerator. The power sources data and status are collected into the archive with the Citect SCADA 7.2 Server SCADA Historian Server. The following operational parameters of the system are expected: current control resolution - 0.05% of IMAX; current stability - 5*10^-4 ; 10 hours current variance - 100 ppm of IMAX ; temperature drift - 40ppm/K of IMAX.

THPPC117	A Control Strategy for Highly Regulated Magnet Power Supplies Using a LQR Approach	controls, damping, simulation, proton	1334
	S. Srivastava, Y. Kumar, A. Misra, V.S. Pandit, S. Sahoo, S.K. Thakur VECC, Kolkata, India
	A linear quadratic regulator (LQR) based proportional-Integrator-derivative (PID) controller is proposed for the SMPS based magnet power supply of the high current proton injector operational at VECC. The state weighting matrices ‘Q’ of the LQR based controller is derived analytically using guaranteed dominant pole placement approach with desired ‘ζ’ (maximum overshoot) and ‘ω’(rise time). The uniqueness of this scheme is that the controller gives the desired closed loop response with minimum control effort, hence avoiding the actuator saturation by utilizing both optimum behavior of LQR technique and simplicity of the conventional PID controller. The controller and power supply parameter perturbations is studied along with the load disturbance to verify the robustness of proposed control mechanism.
