摘要

摘要: 对锦屏深地核天体物理实验JUNA（Jinping Underground laboratory for Nuclear Astro-physics）离子源控制系统进行了研究，采用分布式系统模型构建。硬件采用PLC、串口服务器、伺服电机及工控机等部件实现了离子源设备的远程监测及控制。软件通过建立EPICS IOC运行时数据库，实现了对所有被控设备的集成。用户操作界面采用CSS（Control System Studio）开发，实现了操作人员对所有被控设备的透明访问。基于安全连锁规则设计了机器保护系统，实现了运行异常下的连锁保护。该控制系统应用于国内首套深地实验强流ECR离子源，运行稳定可靠，完全满足JUNA运行及物理实验的需求。

Abstract: The control system for the ion source of the JUNA（Jinping Underground laboratory for Nuclear Astro-physics) was designed and implemented. It is built by using a distributed system model. The hardware adopts PLC, serial device server, servo motor, industrial computer, and other components to realize the remote monitoring and controlling of ion source devices. The software integrates all controlled devices by establishing the EPICS IOC run-time databases. The user interface layer is developed by using Control System Studio to achieve transparent access to all controlled devices by operators. The machine protection system is designed based on safety rules to realize protection in the case of abnormal operations. It is used in the first underground ECR ion source in China and is stable and reliable, which fully meets the needs of the JUNA tuning and physical experiments.

表 4 安全连锁规则

Table 4. Rules of interlock protection

condition of interlock	action
ecrVac ＞ 1 Pa or lebtVac ＞ 1 Pa or rgVac ＞ 200 Pa	bias HV, extraction HV, HV volt and curr of mw are set to 0, interlock of extraction HV opens, FC1 and FC2 push in
biasCurr ＞ 2 mA	extraction HV, HV volt and curr of mw are set to 0, FC1 and FC2 push in
the temperature and pressure of the water are contrary to the thresholds	the solenoid power supply is set to 0, dipole power supply is set to 0 and off, FC1 and FC2 push in, mw interlock, molecular pump controller is set to off
enabled is false	bias HV, extraction HV, parameters of mw are set to 0, FC1 and FC2 push in
vacuum of accelerator is abnormal or stop beam is true	bias HV, extraction HV, HV volt and curr of mw are set to 0, interlock of extraction HV and mw open, FC1 , FC2 push in, delay 200 ms, valve closes
dipole power supply is off or the readback of it is zero	FC1 push in
