The Multiplex Control System for the Cornell 10-GeV Synchrotron

The outlines of a time-sharing multiplex control system for the Cornell 10-GeV electron synchrotron were presented at the First National Particle Accelerator Conference, March 19651. The synchrotron is now nearing completion; injection studies involving more than half the guide-field ring were carried out in 1966. At that time, the multiplex control system was working for most of the needed parameters: we report below on the results of this operating experience. We also present an outline of the steps which are being taken to use a computer for supervision and control of many of the accelerator components.
