摘要

转流加速器振荡器或放大器是一种新型、高效的强相对论电子束驱动微波辐射源。在m=0的非对称版本中，它由一个高压低阻抗电子束在TM/sub 0np/共振之一驱动的单个或多个圆柱腔组成。在没有外加磁场的情况下，由轴向注入的电子束所获得的横向振荡运动是驱动机构的重要组成部分。在广泛的参数范围内系统地测试了穿越加速器理论。仿真旨在验证理论预测，评估转流管作为强微波辐射源的可能性，并研究其作为微波放大器的潜力。数值结果与解析理论在各方面都很吻合。采用CCUBE进行了除径向加载情况外的二维模拟，其中径向加载情况需要三维代码SOS。

Small-signal gain and numerical simulation of transvertron high power microwave sources

The transvertron oscillator or amplifier is a novel and efficient type of intense relativistic electron-beam-driven microwave radiation source. In the m=0 asymmetric version, it consists of single or multiple cylindrical cavities driven at one of the TM/sub 0np/ resonances by a high-voltage low-impedance electron beam. There is no applied magnetic field, and the oscillatory transverse motion acquired by the axially injected electron beam is an essential part of the drive mechanism. The transvertron theory was systematically tested for a wide range of parameters. The simulations were designed to verify the theoretical predictions, assess the transvertron as a possible source of intense microwave radiation, and study its potential as a microwave amplifier. Numerical results agree well in all regards with the analytical theory. Simulations were carried out in two dimensions using CCUBE with the exception of radial loading cases, where the 3-D code SOS was required.<>
