Integration of the Synchrotron Control System to the SPring-8 Control System

At the SPring-8 accelerator complex, control systems of the linac, the booster synchrotron and the storage ring were designed and constructed independently. Since December 1996, the synchrotron started its operation and its cont rol system was useful enough in the commissioning phase and the steady operation [1, 2] . However, more tight combination to the storage ring control system was required for future development and transparent operation of accelerators. It was decided to integrate the present control system of the synchrotron to the SPring-8 standard control system. We gave attention not to interrupt SR user experiments, when we developed and tested the system.
