Abstract
The National Synchrotron Light Source (NSLS) is a synchrotron radiation source designed to provide photons for simultaneous experiments on a large number of individual beam lines. A residual gas analysis (RGA) system has been designed, and is currently being installed, which would protect the beam lines and the storage rings from contamination from any one offending beam line. The system consists of having separate analyzers, with their associated rf generators, in each beam line and storage ring. The analyzers will be multiplexed back to a central controller. A computer is used for routine monitoring and control. The analyzer chosen was the VG Instruments Model SX-200. Typical mass spectra will be presented along with our specifications for the RGA and our vacuum specifications for operating a typical beam line.
