  Facility for Advanced Accelerator Experimental Tests (FACET)-II is an upgrade of the FACET. It uses the middle third of SLAC’s 2-mile long linear accelerator to accelerate the electron beam to 10 GeV, with positron beam to be added in the Stage 2 of the project. Once the project completes in late 2019, it will be operated as a Department of Energy (DOE) user facilities for advanced accelerator science studies. In this paper, we will describe the Radiation Safety Systems (RSS) design and implementation for FACET-II project. RSS include Personnel Protection System (PPS) and Beam Containment System (BCS). Though both systems are safety critical, different technologies are used to implement safety functions. PPS uses Siemens PLC as the backbone for control but legacy CAMAC for data acquisition, while BCS develops customized electronics for faster response to protect safety devices from radiation induced damage.
