EPICS BASED BEAM ORBIT MEASUREMENT SYSTEM FOR

A new beam position measurement system for KEK PF-AR was constructed employing EPICS(Experimental Physics and Industrial Control system). Two new record types were developed for this system. The EPICS database includes more than 3,500 records and SNL programs are used to operate electric relay switching beam position monitors (BPMs). Measured orbit data is agreed with the data which is taken by the existing HIDIC mini computer system. The measurement time is improved with the new system.
