Numerical Analysis of the Field in Helix Traveling Wave Tube

摘要

摘要: 该文对螺旋线行波管中的场进行了数值分析。研究表明数值求解时主从边界条件的位置决定场传播的方向，螺旋线旋转方向决定场的旋转变化方向。螺旋线外各类夹持杆和翼片对螺旋线内部场分布影响很小，场基本随贝塞尔函数分布，但耦合阻抗变化较大，这主要是由于场受螺旋线外结构影响而影响功率分配。同时，对场的各次空间谐波的研究，特别是零次和负一次空间谐波，有利于准确地求解各次空间谐波的耦合阻抗，对提高螺旋线行波管放大器和返波振荡的大信号注波互作用计算的准确性有重要的意义。

Abstract: The field in helix TWT (Traveling Wave Tube) is studied with numerical analysis. By Numerical field analysis, neglected in the theorys, the phenomenon is that, the master and slave face setting decides the wave propagation direction, and the helix rotation decides the fields rotation. Also, the cross-section distribution infection in helix with different rods and vanes outsides of helix are also studied. The field cross-section distribution changes very small, almost with the Bessel function. But the impedance changes much because of the electromagnetic energy re-distribution in rods or vanes. On the other hand, accurate spatial harmonious impedance can be obtained by the spatial harmonious field numerical analysis, especially the mostly used spatial harmonious wave, the 0 and -1 spatial harmonious wave. Above this, the accuracy of the forward and backward beam-wave interaction can be improved.
