Personnel Safety System for the beamlines at the Advanced Photon Source
- Electronics and Computing Technologies Division, Argonne National Laboratory, Argonne, IL 60439 (United States)
The Personnel Safety System (PSS) at the Advanced Photon Source is a high reliability, fail-safe, redundant, engineered safety system that provides personnel access control to prevent inadvertent entry into experimental stations when hazardous radiation conditions exist and warns personnel of changes in safe operating conditions inside these stations. Single fault tolerant access control is provided by two independent interlock {open_quote}{open_quote}chains{close_quote}{close_quote} implemented via programmable logic controllers (PLCs). Reduction of common mode failures is accomplished by different hardware and software platforms for the two chains. The system design is presented. {copyright} {ital 1996 American Institute of Physics.}
