加速器驱动次临界系统注入器离子源控制系统

强流质子源及低能传输线是加速器驱动次临界系统(ADS)项目注入器的重要组成部分,为了保证其工作效率设计了一种基于实验物理及工业控制系统(EPICS)架构的远程控制系统。根据被控设备硬件接口的特点及控制需求分别采用可编程控制器(PLC)和串口服务器等作为控制部件,在主控机中使用LabVIEW编程实现了对系统内所有设备的监控,并借助于DSC模块把设备状态和参数等以过程变量的形式进行网络发布。设计的控制系统具有结构简单、工作可靠的特点,已经在系统调试中发挥了重要作用。

Control system of ion sources for injector of accelerator driven sub-critical system

High-current ion source (IS) is one of the most important subsystems of accelerator driven sub-critical system (ADS), its parameters will determine the performance of the injector beam. So is the low energy beam transport (LEBT) subsystem. In order to confirm the IS and LEBTs effect, a remote control system based on the experimental and physics industrial control system (EPICS) is introduced in this paper. According to the characteristics of the devices interface and the user requirement, a programmable logic controller (PLC) and serial port servers are used as the hardware of the control system. The supervisory control software which is programmed with LabVIEW can control all equipments in the system. All of the parameters such as device status and variables are published on network in form of EPICS process variables (PVs) with the help of LabVIEW DSC module. The designed control system has a simple structure and it works reliably, which has played an important role for the IS and LEBT system testing.
