摘要

用动力学理论分析了三次谐波复合腔回旋管中的注-波互作用

选取了工作点;建立了突变复合腔回旋管的自洽非线性理论模型

该模型既考虑了电子和高频场的自洽相互作用又考虑了复合腔过渡部分模式的耦合

基于该理论模型

对一只三次谐波35GHz突变结构复合腔回旋管中电子注与H

高频场互作用进行了数值模拟

当电流20A

磁场为0.442T时

互作用效率为24%

输出功率为210kW.

Abstract

In this paper

kinetic theory of ECRM is used to analyze third harmonic complex cavity gyroton.A self-consistent nonlinear theoryetical model for a complex cavity gyrotron with abrupt transitions is presented.The model accounts for mode coupling in the transition region of the complex cavity.The interaction between the electron beam and H
