磁控注入电子枪的研究

A Study of Magnetron Injection Gun

介绍了毫米波回旋速调管磁控注入电子枪的结构与特点.依据回旋管对电子枪的要求,考虑相对论效应和空间电荷效应,编制了一套计算程序.利用电子枪模拟程序对电子轨迹进行模拟计算,研究了电极形状、磁场分布以及电子轨迹与电子注参量的影响,为磁控注入电子枪的设计提供了理论依据.

The Structure and characteristics of the magnetron injection gun (MIG) for mm wave gyro-klytron are introduced. According to the requirements for the gyro-klytron, the relativistic effect and the space charge effect is taken into account . A program is developed for CAD. An electron gun code is used to simulate the electron trajectory, the influence of electrode shape, magnet field, electron trajectory on the electron beam have been studied. The theory for design of the electron gun is presented.
