CONTROL-SYSTEM OF THE SYNCHROTRON-RADIATION SOURCE SIBERIA

The SIBERIA accelerator complex includes a 80 MeV electron linac, a 45 0 MeV booster storage ring, a main 2.5 GeV storage ring and two transp ort lines for electron beams. The SIBERIA control system is based on d istributed architecture and uses 24-bit CAMAC-oriented control compute rs and PCs as operator consoles. The paper describes the timing system , the control of the RF system and magnet power supplies, beam diagnos tic and interlock systems, etc. Application software provides the cont rol over beam characteristics, automatic energy ramping and monitoring of the parameters of elements and systems. With the use of the SIBERI A control system the electron beam was accelerated in the linac up to 68 MeV on December 1, 1992, and on December 18, 1992, a circulating be am was generated in the 450 MeV booster ring.
