Description
To address the demands for extensive customization, high measurement throughput, and stringent control accuracy in cyclotron magnetic-field measurement and control, this paper presents a general-purpose, parameterized system. The hardware platform is centered on a Beckhoff PLC, integrating I/O, encoder, and serial-communication modules, and supporting both EtherCAT-based stepper and servo motor drives. On the software side, a C# host application communicates with the PLC in real time via the ADS protocol, and is compatible with magnetic-field mapping apparatuses in both Cartesian and polar coordinate frames, providing real-time monitoring and visualization of all motion-control and field-related parameters. The system offers flexible, parameter-driven configuration that covers core settings for measurement and motion control. The proposed solution has been thoroughly validated on cyclotrons of multiple energy classes at China’s State Power Investment Corporation (SPIC), demonstrating stable and reliable operation. In particular, under servo-drive mode, fully closed-loop control delivers rapid response, significantly improving positioning speed and control accuracy and substantially reducing magnetic-field measurement time.
