毫米波耦合腔行波管非旋转轴对称PPM聚焦系统中的横向磁场

摘要

本文对一种能适应低电压大功率应用需要的毫米波耦合腔行波管的复合型PPM聚焦系统进行了分析，研究了系统中非旋转轴对称性引起的横向磁场，探讨了极靴饱和以及加工和装配误差对聚焦系统的影响，并给出了有关的计算公式。%A combined PPM focusing system for high-power and low-voltage Ka-band coupled-cavity TWTs is analyzed in this paper. The transverse magnetic fields produced by the asymmetric PPM focusing system are investigated, the influences of the saturation of the iron pole pieces as well as fabrication and assembling errors are considered, and the related formulas are also presented.
