CONCEPT OF QUENCH PROTECTION AND AUTOMATIC CONTR DIPOLE MAGNET SYSTEM FOR CEBAF

Unattended operation of HMS 'Magnet system is highly desirable. The burden of operating the magnet is removed from experimentalists. Beside quench detection, several vital system informations and actions of the HMS Dipole Magnet are handled by a local computer and an intelligent industrial control system. In this paper, the overall concept is described and hardware components are introduced. The operation of the system is shown by the example of some different performance states. Potential advantages of such interlinked control and monitoring systems are discussed. 11. QUENCH DETECTION
