| 摘 要： | 设计了对有限宽带状注进行聚焦的周期永磁（PPM）磁场，利用E-GUN，SUPERFISH，MAFIA和PIC模拟软件，建立了计算具有平面对称结构的2维及3维电子光学系统模拟平台,并应用此平台对X波段、100 MW带状注速调管的电子光学系统进行了设计与模拟。结果显示，利用设计的PPM聚焦系统，当磁场周期为60 mm，入口处磁场为0.1 T时，在600 mm的传输距离下，电子注的通过率达到了99.6%。

| Abstract: | Design methods for periodic permanent magnet focusing system are presented.Using E-GUN,SUPERFISH,MAFIA,and PIC,2D and 3D simulation platforms of electron-optical system with plane symmetry are established,and the electron-optical system is X-band 100 MW sheet beam klystron is designed and simulated.The simulation result shows that the beam transmission is 99.6% in a 600 mm propogation distance when the period of the magnetic field is 60 mm,and the magnetic field intensity of the entrance is 0.1 T. |
