Abstract:
The 100 MeV high-intensity proton cyclotron (CYCIAE-100) accelerates H
- beam. Proton beam is extracted by charge exchange stripping extraction system in dual opposite direction. The stripping target is the key part of the beam extraction system. The stripping foil position is decided by 4 movements related with each other. All these movements require high accuracy. For these requirements, PLC module was chosen to control the driving circuit and get the position feedback voltage, which forms negative feedback control loop. The design specification was accomplished. The first 75-100 MeV proton beams were extracted in July, 2014 and the extracting efficiency is better than 99%. By now, the driving control system of stripping target has operated for more than two years, reflecting the good reliability of the system.
