Control Computer System for KEK Proton Synchrotron

A multi-computer network system is used for controlling KEK proton synchrotron. The system is composed of 8 mini-computers-- a central computer, 6 satellite ones and a software development system. Data of the accelerator are taken by the satellite computers which are distributed around the accelerator and then transfered to the central computer through parallel data link lines. The central computer records these data and displays informations to operators. The softwares for the satellite computers are developed on the software development system or the central computer. Development of the system softwares and installation of hardwares are completed and some applications are running now.
