摘要
紧凑型自聚束微波电子枪的实验装置需要相应的控制体系。为此,研制了一套独立于原有大装置(200MeV LINAC)的监测控制系统。该系统基于一般控制系统的三层构架原理,由核心控制电路、光信号发射与接收电路和开关量读写电路组成,实现了时序控制、设备状态监控、联锁控制等功能,并利用上位机与现场处理器通信,达到远程操作的目的。经测试,该系统的性能参数满足并优于实际需求,试运行期间工作稳定可靠,满足实验平台的控制需求。该系统也能直接用于其他小型加速器的控制操作。
An experimental device was recently constructed for testing the beam characteristics of a compact self-bunching RF gun at the National Synchrotron Radiation Laboratory. It designs an independent monitor and control system for the experimental device so as not to disturb the operation of 200MeV LINAC. According to the three-level architecture of a general control scheme, the proposed system consists of circuits that execute kernel control, photosignal emission/reception, and switch values input/output, respectively. It performs timing control, device status monitoring as well as interlock protection, and it can be remotely operated with the assistance of PC software. Testing results show that our system achieves the specified performance and meets the requirement of experimental device stably and reliably. Our proposed system can also be applied to control other small-scale accelerators.
