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.
