摘要

上海质子治疗装置是由中国科学院上海应用物理研究所研制的首台全国产化的质子治疗设备。注入器产生不同能量的质子束满足多样化的治疗所需，而对不同能量束流的轨道约束则由加速器主环动态电源和对应磁铁动态电流的调整来实现。为了避免磁场动态改变时磁铁涡流特性变化带来的干扰，在传统静态电源控制基础上，利用PCASpy模块设计了全新符合实验物理及工业控制系统（Experimental Physics and Industrial Control System，EPICS）规范的上层控制系统，通过高速下载预设电流波形和过程控制，基本消除了涡流影响。该控制系统目前已在主环束流调试过程中正常使用。

Abstract

Background

Shanghai proton therapy facility is the first therapy machine developed in China by Shanghai Institute of Applied Physics

Chinese Academy of Sciences

in which the injector produces different energy proton beams to satisfy requirements of therapy. And the orbit of different beams is constrained by the dynamic power supplies and magnets located on accelerator's main ring.

Purpose

This study aims to design a new top-level control system based on traditional static power supply control technology to avoid eddy current's disturbance during magnetic field changing.

Methods

Physics and Industrial Control System) is employed to design the framework. By transferring of pre-defined current data with high speed and intelligent control technology

the problem of eddy current's disturbance is solved affirmatively.

Results and Conclusion

This control system has been tested and verified by accelerator main ring's commissioning.
