Radiation Safety System of the B-Factory at the Stanford Linear Accelerator Center
Abstract
The radiation safety system (RSS) of the B-Factory accelerator
facility at the Stanford Linear Accelerator Center (SLAC) is
described. The RSS, which is designed to protect people from prompt
radiation exposure due to beam operation, consists of the access
control system (ACS) and the radiation containment system (RCS). The
ACS prevents people from being exposed to the very high radiation
levels inside a beamline shielding housing. The ACS consists of
barriers, a standard entry module at every entrance, and beam
stoppers. The RCS prevents people from being exposed to the radiation
outside a shielding housing, due to either normal or abnormal
operation. The RCS consists of power limiting devices, shielding,
dump/collimator, and an active radiation monitor system. The
inter-related system elements for the ACS and RCS, as well as the
associated interlock network, are described. The policies and
practices in setting up the RSS are also compared with the regulatory
requirements.
