The Beam Screening Device for the Production of Radioisotopes Based on 100 MeV High-Flow Proton Cyclotron

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.
