- 1. China Science and Technology Univ., Hefei (China). National Synchrotron Radiation Laboratory
Description
Upgrade project of the 50 MW klystron modulators of Hefei Light Source (HLS) was firstly introduced. PLC control system of modulators was employed to replace the old control and monitor system, which was based on relay logic circuit and manual operation method. the PLC system becomes a sub system of the new EPICS control system of HLS. Constant-current, switch-mode and high voltage power supplies were adopted to replace the old 50 Hz power supplies. The technology of modulators was improved and operation was more reliable. The design method, hardware and software of PLC control of modulators were described and the performance was presented. (authors)
