摘　　要：在进行放射性同位素生产实验时,有时需要100 MeV强流质子回旋加速器引出单圈束流来满足实验要求。目前100 MeV强流质子回旋加速器束流引出时存在严重圈重叠问题,因此需要设计一款束流筛选装置对引出束流品质进行改善以满足实验要求。该束流筛选装置具有基于100 MeV强流质子回旋加速器的框架结构与狭缝运动系统,以及基于PLC设计的控制系统控制步进电机并利用电子尺和按偏差的比例P、积分I和积分D(PID)控制的算法实现闭环控制。经过多次运行调试,机械装置的运动精度在±0.2 mm,且在加速器运行过程中可以实现对束流的筛选。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.
