摘要
通过对不同耦合腔结构中电子注传输特性的研究,设计了长周期永磁聚焦系统,解决了影响电子注传输的横向磁场,开口磁环和磁场过渡区等问题,运用3维程序对X波段耦合腔行波管电子光学系统进行模拟计算,电子注通过率达到100%,波动9%,与耦合腔行波管实验要求一致。
Designed through research of electron beam transmission characteristic in different coupled cavity structures,long periodic permanent magnetic focusing system solves problems of factors influencing electron trajectories such as transverse magnetic field,open magnetic ring and magnetic field in transition region.3D program simulation of electron optics system for X-band coupled cavity traveling wave tube shows 100% transfer efficiency of electron beam and 9% ripple of electron beam,which accords with requirements of coupled cavity traveling wave tube experiment.
