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.
