PROGRESS OF A CONTROL SYSTEM FOR SLOW-EXTRACTION BEAM LINES AT J-PARC

We have developed the core part of the local control system for the slow-extraction beam lines in the Hadron Experimental hall (HD-hall) at Japan Proton Accelerator Research Complex (J-PARC). The existing system for the magnet power supplies can communicate with the accelerator control system via relational databases. The read-out electronics for beam loss monitors and profile monitors have been developed and tested in the existing beam lines at KEK 12GeV Proton Synchrotron (12GeV-PS). The VME modules to transport analog signals for real-time feedback via 3 km optical cables have been designed. The present manuscript describes the details of each subsystem.
