L C L S C O N C E P T U A L D E S I G N R E P O R T Chambers (BSOICs), and those burn-through monitors that are controlled through the PPS. The PPS will remain largely the same in terms of its design, function, and configuration as other PPS to installations used at SLAC and SSRL, and all additions will conform to the Radiation Safety Systems Technical Basis Document, Chapter 2 Personnel Protection Systems (SLAC-I-720- 0A05Z-002). 13.1.3 Beam Containment System The Beam Containment System (BCS) prevents accelerated beams from diverging from the desired channel, and detects excessive beam energy or intensity that could cause unacceptable radiation levels. Beam containment is usually accomplished by a combination of passive devices such as collimators, which are designed to absorb errant beams, and active devices such as electronic monitors that shut off the beam when out of tolerance conditions are detected. The present BCS in the Linac consists of passive mechanical devices (such as slits, collimators, magnets, electron beam stoppers, and dumps) and active electronic devices such as average current monitors, burn through monitors, and beam shut off ion chambers. Additionally the LCLS will install photon stoppers, ion chambers, and burn-through monitors for the proposed beamlines. Gas absorption cells are planned to be installed in critical places, for attenuating the beam as needed. 13.1.4 Radiation Safety Training In accordance with SLAC's Site Access and Identification Badges Policies and Procedures (SLAC-I-720-0A0Z-002-R001), all individuals at SLAC who enter the Radiologically Controlled Area (RCA) or the Accelerator Area must be either properly trained or escorted by a properly trained individual. Levels of training depend on the area to be accessed and in some cases the duration of the individual’s stay. (See Table 13-2.) 13-6 ♦ E N V I R O N M E N T , S A F E T Y A N D H E A L T H A N D Q A
