摘要

摘要: 该文基于Orprogr软件，在X波段模拟设计出耦合腔行波管的期待电性能，并利用互作用后的电子注为入口条件，优化设计出收集效率大于71.5%、电子注着陆相对均匀的三级降压收集极。在上述条件下，讨论了电子进入收集极层流性(速度比)、电极形状、电极电压以及收集极内电场分布对电子运动的影响，从物理上给出了电子注在收集极表面着陆特点的详细分析。

Abstract: In this article, based on a coupled cavity TWT design software, Orprogr code, the simulation design of a X band coupled cavity TWT is performed for realizing the expected electric characteristics. Under the condition of the above-mentioned design results, a depressed collector is designed with the minimum collector efficiency of 71.5% and the electron beam may relatively evenly spreads on the surface of each sub-area of the depressed collector. Then the influence of laminar flow, electrode shape, voltage drop and electrical field on the distribution of the beam is discussed by analyzing the spreading of electron beam on the surface of each sub-area of the depressed collector.
