Start-Up of the New CPS Controls System and Switch-Over of the 800 MeV Booster Controls

The new CPS controls system was successfully put into operation on 19 November, 1980, when the 800 MeV Booster, after switching over to the new system, was started up for particle physics. A subset of the new system had already been installed on the Antiproton Accumulator in Spring 1980 and has reliably served several months of engineering run. The Booster machine and control of the CPS cycle generation are now routinely operated by the new system which is based on distributed processing, extensively applying microprocessors in the interface. The problems encountered in converting existing accelerator controls, the control switchover itself and operational experience gained up to the date of the conference are described.
