摘要

摘要: 中国科学院高能物理研究所第二台硼中子俘获治疗（BNCT02）加速器主要由1台离子源、1条低能束流传输线、1台射频四极加速器和3条高能束流传输线组成。为了保障BNCT02加速器的安全运行，设计了基于横河PLC和实验物理及工业控制系统（EPICS）软件工具包的机器保护系统。为了增强安全性，该系统采用了冗余设计，由两套完全独立且主要输入、输出信号一致的子系统构成。测试结果表明，BNCT02加速器机器保护系统的响应时间小于1.6 ms，且具有稳定可靠性高的特点，满足BNCT02加速器运行的需要。

Abstract: The RF linac dedicated to boron neutron capture therapy clinic facility (BNCT02) in our institute is mainly composed of an ion source, a low energy beam transmission line, a radio frequency quadrupole accelerator and three high energy beam transmission lines. This study aims to ensure the safe operation of the BNCT02 accelerator. A machine protection system (MPS) was designed based on Yokogawa PLC and Experimental Physics and Industrial Control System (EPICS) software toolkit. In order to improve safety, the system adopts a redundant design, consisting of two completely independent subsystems with consistent main input and output signals. The test results show that the response time of the BNCT02 accelerator MPS is less than 1.6 ms, and it has the characteristics of high stability and reliability, which meets the operational requirements of the BNCT02 accelerator.
