摘要

采用π型慢波结构的大功率行波管具有１５％带宽、无“兔耳”效应以及可实现１００ｋＷ甚至更高的峰值功率，本文运用场匹配法对行波管用的π型慢波结构进行了理论分析，给出了这种结构的色散方程和耦合阻抗，对π型慢波结构进行精细冷测后表明，计算机数值计算的理论值与冷测实验结果吻合良好。为使行波管单模工作而在π型结构中增加搭扣带后的主模色散计算方法也已给出，并取得了与实测较一致的满意结果，本文还叙述了该结构的尺寸变化对色散和耦合阻抗的影响．理论与实验的一致性，证实了分析的合理和计算程序的可信，它为设计大功率π型慢波结构行波管提供了理论与实验基础．

Abstract

The theoretical analysis of the π-type slow-wave structure for TWT is worked out by using the field-matching method.The dispersion characteristics and the coupling impedance of this structure

which has a 15% bandwidth

no"Rabbit Ears"efffect and 100kW even more peak power handling ability

are discussed.It is shown that the theoretical calculation is in a good agreement with experimental results.After putting the straps which can ensure the operation of TWT’s dominate mode

their influence on the dispersion of the structure is also given.This theoretical method can be used for the analysis and design of π-Structure.
