	Funding: CNRS, MESR, CG91, CRiDF, ANR Cilex-Apollon is a high intensity laser facility delivering at least 5 PW pulses on targets at one shot per minute, to study physics such as laser plasma electron or ion accelerator and laser plasma X-Ray sources. Under construction, Apollon is a four beam laser installation with two target areas. Such a facility causes many risks, in particular laser and ionizing radiations. The Personal Safety System (PSS) ensures to both decrease impact of dangers and limit exposure to them. Based on a risk analysis, Safety Integrity Level (SIL) has been assessed respecting international norms IEC 62061 and IEC 61511-3. To conceive a high reliability system a SIL 2 is required. The PSS is based on four laser risk levels corresponding to the different uses of Apollon. The study has been conducted according to norm EN 60825. Independent from the main command -control network the distributed system is made of a safety PLC and equipment, communicating through a safety network. The article presents the concepts, the architecture the client-server architecture, from control screens to sensors and actuators and interfaces to the access control system and the synchronization and sequence system.

	Being responsible for 3 GeV booster synchrotron for the National Synchrotron Light Source (NSLS-II, BNL, USA) design and manufacture, Budker Institute of Nuclear Physics also designs the booster control and diagnostic system. Among others, the system includes interlock system consisting of equipment protection system, vacuum level and vacuum chamber temperature control system, beam diagnostic service system. These subsystems are to protect facility elements in case of vacuum leakage or chamber overheating and to provide subsidiary functions for beam diagnostics. Providing beam interlocks, it processes more then 150 signals from thermocouples, cold and hot cathode vacuum gauges and ion pump controllers. The subsystems contain nine 5U 19" chassis with hardware of each based on Allen-Bradley CompactLogix Programmable Logic Controller. All the interlock related connections are made with dry contacts, whereas system status and control is available through EPICS channel access. All operator screens are developed with Control System Studio tooling. This paper describes configuration and operation of the booster interlock system.

MOPPC052	ESS Bilbao Interlock System Approach	PLC, EPICS, controls, ion	206
	D.P. Piso, I. Arredondo, M. Eguiraun, S. Varnasseri ESS Bilbao, Zamudio, Spain
	Funding: ESS Bilbao This paper describes the approach used at ESS Bilbao initiative for the implementation of the Interlock System. The system is divided into two parts depending on the required speed for the system response: Slow Interlocks (>100 msec.) and Fast Interlocks (<100 msec.). Besides, both interlocks parts are arranged in two layers: Local Layer and Master Layer. The Slow Interlocks subsystem is based on PLCs. This solution is being tested in the ESS Bilbao ECR ion source with positive results and the first version design is now complete for the LEBT system. For the Fast Interlocks local layer part, a solution based on NI cRIO has been designed and tested. In these tests a maximum response time of 3.5 μs. was measured for analog acquisition, threshold comparison and signal generation. For digital signals the maximum time response of a similar process was 500 nsec. . These responses are considered valid for the standard need of the project. Finally, to extract information from the interlocks system and monitor it, the Modbus/EPICS interface is used for Slow Interlocks, while EPICS output is produced by NI cRIO. Hence, it is planned to develop a light pyQT solution to perform this task.

MOPPC069	Operational Experience with the LHC Software Interlock System	injection, software, operation, hardware	258
	L. Ponce, J. Wenninger, J.P. Wozniak CERN, Geneva, Switzerland
	The Software Interlock System (SIS) is a JAVA software project developed for the CERN accelerators complex. The core functionality of SIS is to provide a framework to program high level interlocks based on the surveillance of a large number of accelerator device parameters. The interlock results are exported to trigger beam dumps, inhibit beam transfers or abort the main magnets powering. Since its deployment in 2008, the LHC SIS has demonstrated that it is a reliable solution for complex interlocks involving multiple or distributed systems and when quick solutions for un-expected situations is needed. This paper is presenting the operational experience with software interlocking in the LHC machine, reporting on the overall performance and flexibility of the SIS, mentioning the risks when SW interlocks are used to patch missing functionalities for personal safety or machine protection.

	ITER is formed by systems which shall be pushed to their performance limits in order to successfully achieve the scientific goals. The scientists in charge of exploiting the tokamak will require enough operational flexibility to explore as many plasma scenarios as possible while being sure that the integrity of the machine and safety of the environment and personnel are not compromised. The I&C Systems of ITER has been divided in three separate tiers: the conventional I&C, the safety system and the interlock system. This paper focuses on the latter. The design of the ITER interlocks has to take into account the intrinsic diversity of ITER systems, which implies a diversity of risks to be mitigated and hence the impossibility to implement a unique solution for the whole machine. This paper presents the chosen interlock solutions based on PLC, FPGA, and hardwired technologies. It also describes how experience from existing tokamaks has been applied to the design of the ITER interlocks, as well as the ITER particularities that have forced the designers to evaluate some technical choices which historically have been considered as non-suitable for implementing interlock functions.

THPPC076	Re-Engineering Control Systems using Automatic Generation Tools and Process Simulation: the LHC Water Cooling Case	controls, PLC, simulation, operation	1242
	W. Booth, E.B. Blanco Vinuela, B. Bradu, L. Gomez Palacin, M. Quilichini, D. Willeman CERN, Geneva, Switzerland
	This paper presents the approach used at CERN (European Organization for Nuclear Research) for the re-engineering of the control systems for the water cooling systems of the LHC (Large Hadron Collider). Due to a very short, and therefore restrictive, intervention time for these control systems, each PLC had to be completely commissioned in only two weeks. To achieve this challenge, automatic generation tools were used with the CERN control framework UNICOS (Unified Industrial Control System) to produce the PLC code. Moreover, process dynamic models using the simulation software EcosimPro were developed to carry out the ‘virtual’ commissioning of the new control systems for the most critical processes thus minimizing the real commissioning time on site. The re-engineering concerns around 20 PLCs managing 11000 Inputs/Outputs all around the LHC. These cooling systems are composed of cooling towers, chilled water production units and water distribution systems.
