Ion pump control system designed for HIRFL

Background Ion pump control system of HIRFL is designed based on the real-time distributed control software, EPICS. The hardware architecture, communication principle, database design and interlock design are introduced and elaborated in the paper.
Methods PLC has been adopted to realize functions such as control monitoring and data communication. Interlock protect ion has been designed for ion pump control system to prevent damaging from high voltage.
Results The test results show that the system has fast response function and high-speed data processing during the beam running and tuning. The response time of the system could reach 100 ms, the rate of data acquisition reaches to 10 time/s and the interlock protection time less than 40 ms.
Conclusion The reliable and stable long-term operation of the vacuum system indicates that the performance has been constantly improved with the continuous optimization of the ion pump control system.
