合肥国产超导质子回旋加速器主真空控制系统的设计与实现

he superconducting proton synchrotron is one of the most advanced domestically developed medical radiation therapy devices in China. As a crucial subsystem of the accelerator, the vacuum system provides the necessary operational environment for particle acceleration. This study aims to design the vacuum control system for the accelerator to maintain a stable high vacuum environment. Based on the vacuum design requirements of the accelerator, the design of the vacuum control system was accomplished using Siemens Programmable Logic Controller (PLC) hardware and the Experimental Physics and Industrial Control System (EPICS) software framework. The content includes the overall structure of the control system, system operational logic, user interface design, and safety interlocks. The results indicate that, during long-term operation, the system maintains a high vacuum level, and the control performance and stability meet the design requirements, ensuring the stable operation of the accelerator.
