Reconfigurable Embedded Interface System for High Energy Accelerators
N.Kanaya* (Ibaraki University Electrical and Electronic Eng.)
A reconfigurable embedded interface system has been developed using micro-controllers for high energy accelerators. The system has up to 28 digital I/Os and 8-channel AD converters(10 bits), interrupt functions allowing control systems to access any accelerator components over the network. The components involve beam-position monitors, current monitors for bending magnets, ion pumps, vacuum valves, insertion devices, RF components, ion-gauges, and beamlines. The interface is programmed to carry out specific tasks in accordance with requirements for experiments and research purpose. The interface employs PIC micro-controllers, and it can be connected to the network. The interface is easily reconfigured using its boot-loader by uploading a new program from the remote distributed control system through the network. The test of the system has been successfully carried out for a monitoring system for AC power consumption at the control room of B-Factory, KEK. The design and implementation of the reconfigurable interface embedded system for high energy accelerators are described in this paper.
