The ESRF Beamline Personnel Safety System

The present paper describes the ESRF Beamline Personnel Safety System. A short description of the basic hardware of the system is given, followed by the description of its functionality. We describe the way the different beamline safety systems are linked to the general accelerator personnel safety system. Since the ESRF has a large number of beamlines (by the end of 1996, 34 beamlines will be installed, with a total of 105 hutches), we have taken great care to design a modular system, which has been optimised to reduce the installation time.
