The Continuous Electron Beam Accelerating Facility (CEBAF) is a new generation particle accelerator for basic research in nuclear physics. After a successful commissioning period, we started delivering beam to first experiments in November 1995, with beam availability of better than 70%. In this paper we present specifications, design, and discussion of operational experience with the personnel safety and machine protection implementation of CEBAF’s beam loss accounting system. The diagnostics section of this system uses low Q TM010 stainless steel cavities as beam current monitors to sample beam current throughout the beam path. The associated rf front end and analog signal conditioning electronics output signals proportional to beam current or beam loss, depending on the implementation. The personnel safety and the machine protection systems then use this current or loss information to turn off the beam when hazardous conditions occur. This system, implemented in its final configuration in January 1996,... |
