Abstract

A control system has been designed for the 1.8-GeV synchrotron-radiation source at Tohoku University Synchrotron Radiation Facility (TSRF), Sendai-city, Japan. TSRF is a third-generation synchrotron-radiation facility proposed at Tohoku University, Sendai, Japan. The control system comprises three physical layers: UNIX workstations, an FDDI (fiber distributed data interface) high-speed network, and VME modules. UNIX workstations are employed for the upper layer that provides process control and a user interface. The FDDI provides a 100-Mbps, token-passing, dual-ring LAN using a fiber-optic link suitable for reliably exchanging control data. On the bottom layer, there are VME crates with high performance CPUs that are interconnected to the magnets, RF, vacuum, beam-position monitors, wigglers/undulators, beamlines and related components of the storage ring for local process control. The design of the TSRF control system is discussed
