MOPMS001	The New Control System for the Vacuum of ISOLDE	vacuum, controls, hardware, software	312
	S. Blanchard, F. Bellorini, F.B. Bernard, E. Blanco Vinuela, P. Gomes, H. Vestergard, D. Willeman CERN, Geneva, Switzerland
	The On-Line Isotope Mass Separator (ISOLDE) is a facility dedicated to the production of radioactive ion beams for nuclear and atomic physics. From ISOLDE vacuum sectors to the pressurized gases storage tanks there are up to five stages of pumping for a total of more than one hundred pumps including turbo-molecular, cryo, dry, membrane and oil pumps. The ISOLDE vacuum control system is critical; the volatile radioactive elements present in the exhaust gases and the High and Ultra High Vacuum pressure specifications require a complex control and interlocks system. This paper describes the reengineering of the control system developed using the CERN UNICOS-CPC framework. An additional challenge has been the usage of the UNICOS-CPC in a vacuum domain for the first time. The process automation provides multiple operating modes (Rough pumping, bake-out, high vacuum pumping, regeneration for cryo-pumped sectors, venting, etc). The control system is composed of local controllers driven by PLC (logic, interlocks) and a SCADA application (operation, alarms monitoring and diagnostics).

MOPMS016	The Control System of CERN Accelerators Vacuum (Current Status and Recent Improvements)	vacuum, controls, interface, status	354

	The vacuum control system of most of the CERN accelerators is based on Siemens PLCs and on PVSS SCADA. The application software for both PLC and SCADA started to be developed specifically by the vacuum group; with time, it included a growing number of building blocks from the UNICOS framework. After the transition from the LHC commissioning phase to its regular operation, there has been a number of additions and improvements to the vacuum control system, driven by new technical requirements and by feedback from the accelerator operators and vacuum specialists. New functions have been implemented in PLC and SCADA: for the automatic restart of pumping groups, after power failure; for the control of the solenoids, added to reduce e-cloud effects; and for PLC power supply diagnosis. The automatic recognition and integration of mobile slave PLCs has been extended to the quick installation of pumping groups with the electronics kept in radiation-free zones. The ergonomics and navigation of the SCADA application have been enhanced; new tools have been developed for interlock analysis, and for device listing and selection; web pages have been created, summarizing the values and status of the system. The graphical interface for windows clients has been upgraded from ActiveX to QT, and the PVSS servers will soon be moved from Windows to Linux.

	LIA-2 is an electron Linear Induction Accelerator designed and built by BINP for flash radiography. Inductors get power from 48 modulators, grouped by 6 in 8 racks. Each modulator includes 3 control devices, connected via internal CAN bus to an embedded modulator controller, which runs Keil RTX real-time OS. Each rack includes a cPCI crate equipped with x86-compatible processor board running Linux. Modulator controllers are connected to cPCI crate via external CAN bus. Additionally, brief modulator status is displayed on front indicator. Integration of control electronics into devices with high level of electromagnetic interferences is discussed, use of real-time OSes in such devices and interaction between them is described.

WEPMS023	ALBA Timing System - A Known Architecture with Fast Interlock System Upgrade	timing, diagnostics, booster, network	1024

	Like most of the newest synchrotron facilities the ALBA Timing System works on event based architecture. Its main particularity is that integrated with the Timing system a Fast Interlock System has been implemented which allows for an automated and synchronous reaction time from any-to-any point of the machine faster than 5μs. The list of benefits of combining both systems is large: very high flexibility, reuse of the timing actuators, direct synchronous output in different points of the machine reacting to an interlock, implementation of the Fast Interlock with very low cost increase as the timing optic fiber network is reused or the possibility of combined diagnostic tools implementation for triggers and interlocks. To enhance this last point a global timestamp of 8ns accuracy that could be used both for triggers and interlocks has been implemented. The system has been designed, installed and extensively used during the Storage Ring commissioning with very good results.

	Funding: Diamond Light Source LTD The Diamond Light Source Machine Protection System manages the hazards from high power photon beams and other hazards to ensure equipment protection on the booster synchrotron and storage ring. The system has a shutdown requirement, on a beam mis-steer, of under 1msec and has to manage in excess of a thousand interlocks. This is realised using a combination of bespoke hardware and programmable logic controllers. The structure of the Machine Protection System will be described, together with operational experience and developments to provide post-mortem functionality.

	The Personnel Safety System is based on PILZ PLCs, SIL3 compatible following the norm IEC 61508. It is independent from other subsystems and relies on a dedicated certification by PILZ first and then by TÜV. The Equipment Protection System uses B&R hardware and comprises more than 50 PLCs and more than 100 distributed I/0 modules installed inside the tunnel. The CPUs of the PLCs are interconnected by a deterministic network, supervising more than 7000 signals. Each Beamline has an independent system. The fast interlocks use the bidirectional fibers of the MRF timing system for distributing the interlocks in the microsecond range. Events are distributed by fiber optics for synchronizing more than 280 elements.

	J.-C. Chapuis, J.P.A. Arnoul, A. Hurst, M.G. Manson CEA, Le Barp, France
	The French CEA (Commissariat à l'Énergie Atomique) is currently building the LMJ (Laser MégaJoule), at the CEA Laboratory CESTA near Bordeaux. The LMJ is designed to deliver about 1.4 MJ of 0.35 μm light to targets for high energy density physics experiments. Such an installation entails specific risks related to the presence of intense laser beams, and high voltage power laser amplifiers. Furthermore, the thermonuclear fusion reactions induced by the experiment also produce different radiations and neutrons burst and also activate some materials in the chamber environment. Both risks could be lethal. This presentation (paper) discusses the SSP (system for the personnel safety) that was designed to prevent accidents and protect personnel working in the LMJ. To achieve the security level imposed on us by labor law and by the French Safety Authority, the system consists of two independent safety barriers based on different technologies, whose combined effect can reduce to insignificant level the occurrence probability of all accidental scenarios identified during the risk analysis.
