<正>A new controlling system is designed for HV-ECR platform and its beam-line. The software of the controlling system is created by Visual-C, and Visual-B language. The software will read and write data to the controlled devices, and display the status of the devices. The controlled devices include: (1) step-motor system, which adjust the slits to define beam spots; (2) pneumatic system, which moves the Faraday-Cup and the monitoring screen on the beam-line; and (3) HV-platform controlling system.
