Radiation Safety Interlock System (RSIS) for the Shanghai Synchrotron Radiation Facility (SSRF) has been built and operated more than one year, it is composed of two subsystems, the Access Control System (ACS) and the Radiation Containment System (RCS).The ACS prevents personnel from being exposed to the extremely high radiation inside the SSRF shielding tunnel during machine operation. The RCS prevents personnel from being exposed to the high radiation outside a shielding tunnel during either normal or abnormal operation. The implementation of the ACS is based on the Programmable Logic Controllers, key transfer interlocking systems and ID Card System. The RSIS is based on fail-safe, redundancy, multiplicity. Any violation of the RSIS will result in the inhibiting of redundant permission to the associated interlock systems, and cease the injection process and eliminate the entire stored electron beam in the SSRF. This paper describes the system design, the logic, and some experience of using RSIS systems at SSRF.

Shanghai Synchrotron Radiation Facility (SSRF) is the first third-generation synchrotron radiation facility in China and it will be completed and put into use in April 2009. Radiation Monitoring System in SSRF is an important part of radiation safety system. This paper describes the Radiation Monitoring System in real time and its performance during beam commissioning. This system consists of sets of neutron and gamma monitors and data acquisition and computer system mounted in central control room. The types and features of the monitors and the functions of the computer system based on EPICS, SAD, PYTHON and MYSQL are given in detail. The performance of the system during the commissioning showed that the system performs as design expected, and can successfully prevent people from being exposed to abnormal radiation level.
