Beam Loss Monitor System for SSRF Storage Ring

Abstract

A Beam Loss Monitor (BLM) system has been designed for Shanghai Synchrotron Radiation Facility (SSRF). The BLM system is utilized to detect beam loss around the electron storage ring. It will be helpful to find out the position of vacuum leakage, regulate the machine operation parameters, and study the beam lifetime. This paper will discuss some considerations in the BLM system design, including the detector selection, the beam loss mechanism, the detector location along the ring, and the structure of BLM system.
