耦合腔行波管三维大信号程序设计

Three-Dimensional Large-Signal Computer Program for Coupled-Cavity Traveling Wave Tubes

讨论了耦合腔行波管大信号互作用的物理模型和三维计算机程序设计，考虑了电子注的圆环模型在径向、轴向的速度以及圆环旋转的角速度，详细研究了电子注对场的激励形式、返波的影响和相对论修正等因素，编制出了耦合腔行波管三维大信号程序。计算结果与实际相符。

The physical model and numerical method for coupled-cavity TWT's large signalinteraction are given.In the physical model,the axial and radial velocities and the angular velocities of ringsare considered.The mechanism of the elctron beam-wave interactions as well as the backward waveinfluence and the relatirutic effect are discussed in detail.The computation results for several coupled-cavity TWTS show good agreements with the experiment values.
