Description
The China Institute of Atomic Energy is developing an ultra-compact multi-particle superconducting cyclotron, which can provide two different ions, including a particle and H_2^+ with corresponding energies. To ensure convenient operation and stabilize the beam current, a PLC-based control system with comprehensive interlock protection has been developed. This paper presents the design of a PLC-based control system. The system utilizes a distributed industrial network architecture, enabling supervisory control of key subsystems, including the superconducting magnet, radio frequency system, and ion source. It allows real-time monitoring and precise control, integrating functions such as interlock protection, data acquisition, remote operation, and fault diagnosis to ensure stable and reliable cyclotron operation. An innovative PLC-based automated protection system for low-temperature superconducting coils has been developed to prevent quenching. It’s believed that such a system will significantly improve reliability and maintainability of the superconducting cyclotron. In this paper, a multi-mode operation design will be reported, which combines automation with manual intervention, offering high scalability and fault tolerance. The development of a generalized, intelligent PLC control program will also be reported, which can provide reliable control of the ultra-compact multi-particle cyclotron for various applications, including research on biological effects.
