- 24 Downloads
The control system for ion source is based on distributed architecture. The hardware structure, working principle, interlock design and graphics interface design are introduced and stated in this paper.
To improve the accuracy and usability of the electron cyclotron resonance ion source with advanced design for HIMM.
The data acquisition system is based on PLC and FPGA integrated circuit. Interlock protection is designed for vacuum system, power supplies system and cooling water system.
The control system is tested with C5+ ion beam, where fast reaction time and high-precision data processing during beam tuning have verified the stability and maintainability of the control system.
The latest results and the reliable long-term operation of the accelerator demonstrate that the performance has been continually improved with the development of the optimized control system.
