Abstract

A method is proposed for producing microwave generation in a relativistic magnetically insulated vircator in the under-limit mode of an electron beam. The method is implemented if the repeated or multiple passage of the electron beam of the drift tube is organized. In this case, a virtual cathode is formed in the vircator and the powerful microwave generation occurs. Using the particle-in-cell (PiC) simulation, the microwave producing characteristics of the radiation are calculated upon the re-introduction of the beam into the drift tube and the nonlinear dynamics of the electron beam is studied.

带下限电子束的磁隔离振荡器的仿真

摘要

提出了一种在相对论性磁绝缘的振动器中以电子束的下限模式产生微波的方法。如果漂移管的电子束的重复或多次通过被组织，则实施该方法。在这种情况下，虚拟的阴极形成在振动器中，并且产生强大的微波。使用粒子内（PiC）模拟，在将电子束重新引入漂移管后计算出辐射的微波产生特性，并研究了电子束的非线性动力学。
