Beschreibungen/Notizen

• In some radioisotope production experiments，100 MeV high-current proton cyclotron is required to extract a single-turn beam to meet the experimental requirements，but at present，there is a serious problem of turn overlap when the beam is extracted，and a beam screening device needs to be designed to improve the quality of the drawn beam. The beam screening device has a frame structure and slit motion system based on the cyclotron，and a control system based on PLC design to control the stepper motor and use the electronic ruler and PID control algorithm to achieve closed-loop control. After many times of operation and debugging，the motion accuracy of the mechanical device is ±0.2 mm，and the beam screening can be realized during the operation of the accelerator，which has reference significance for the design and manufacture of the cyclotron beam screening device.
