Concept of quench protection and automatic control for the HMS dipole magnet system for CEBAF

Unattended operation of the CEBAF high momentum spectrometer (HMS) magnet system is considered. Beside quench detection, several vital system information and actions of the HMS dipole magnet are handled by a local computer and an intelligent industrial control system. The overall concept is described and hardware components are introduced. The operation of the system is shown by an example of some different performance states. Potential advantages of such interlinked control and monitoring systems are discussed.<
