WPO023	Personnel Safety System in SESAME	booster, controls, PLC, microtron	87
	M. Mansouri Sharifabad, A. Ismail, I. Saleh SESAME, Allan, Jordan
	Funding: International Atomic Energy Agency (IAEA) SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East) is a “third-generation” synchrotron light source under construction in Allan, Jordan. Personnel Safety System (PSS) in SESAME restricts and controls the access to forbidden areas of radiation. The PSS is an independent system which is built on Safety PLCs. In order to achieve the desired Safety Integrity Level which is SIL-3, as defined in IEC 61508, several interlocks and access procedures have been implemented in the system fulfilling characteristics such as fail-safe, redundancy and diversity. Also a system meant for monitoring and diagnostics of PSS is built based on EPICS and HMI. PSS PLCs which implement interlock logic send all the input and output bits and PLC status information to EPICS IOC which is not an integral function of PSS operation. This IOC will be connected to other control system’s IOCs to send informative signals describing the status of PSS to the main control system in SESAME. In addition, 5 combined Gamma-Neutron radiation monitors which are distributed around and over the booster area send interlock signals to personnel safety system.
