Computer Control System for High-Intensity Ion Beam Facility

In order to achieve automation system of the low-energy high-intensity ion beam and improve anti-jamming capacity and stability, the computer control system of lowenergy highintensity ion beam was developed. The Siemens S7-300PLC programmed by STEP7 V5 configuration software was used and placed in three different electric levels. Human machine interface was programmed by Lab Windows/CVI 6.0. The structure， choice of control hardware， the fulfilled function of control software were described. At the same time, some methods of suppressed interference were discussed at the course of the debugging.
