摘要
分析并推导出了环形强流电子束的稳定传输条件,通过静电磁场模拟计算对CHP01强流电子加速器二极管引导磁场的位形分布、幅值大小及磁场电源进行了优化设计.经实验调试及束斑测量,表明设计的1秒磁场满足束流稳定传输条件,能使电压800kV、电流8kA、脉冲宽度40ns、脉冲重复频率100Hz的环形强流电子束稳定传输,并已成功运用于CHP01强流电子加速器束流传输系统.
The stability condition of intense annular electron beam transmission is analyzed and deduced. Based on the static electricmagnetic field simulation, the position and configuration of the guide magnetic-field and its magnitude as well as its power supply are designed. Then the experiments of repetitive rate and intense current electron-beam diode are carried out on CHP01 generator, and the image of the intense annular electron beam is measured too. The results show that the designed 1-s magnetic field satisfies to the stability condition of intense annular electron beam transmission. It can stably transmit intense current electron-beam pulse of 800kV/8kA, pulse width 40ns, repetition rate 100Hz. And now the 1-s magnetic-field system is successfully used on CHP01 accelerator.
