Vacuum control system of the injector Ⅱ for accelerator driven sub-critical system

Vacuum system is one of the most important subsystems of the injector Ⅱ for accelerator driven sub-critical system (ADS), whose performance determines the quality of the injectors beam. A remote control system based on the Experimental and Physics Industrial Control System (EPICS) is introduced to serve the vacuum system and to validate its performance. Programmable Logic Controller (PLC) and serial port servers are chosen to fulfill the requirements and to implement the control functions. The supervisory control procedure is programmed with LabVIEW , and the communication with EPICS is implemented with the use of the Datalogging Supervisory Control (DSC) module. The vacuum control system has a simple structure and works stably, which will contribute to the 5 MeV beam commission.
