摘要
带状注速调管是采用宽高比值很大的薄矩形注来降低空间电荷效应,采用特殊的高频结构来增加功率容量,从而使注波互作用效率得到提高的一种新型微波电真空器件。本文对带状注速调管的谐振腔进行研究,通过三维电磁模拟软件分别对单间隙和多间隙谐振腔的频率特性进行了计算,并对其进行了分析和讨论。
The sheet beam klystron is a new kind of microwave vacuum device, which uses a high as- pect ratio, thin rectangular beam to reduce space charge effects, the special RF structure to increase power capability and beam-wave interaction efficiency. In this paper, the one-cell and three-cell cavities of X-band sheet beam klystron were studied. Analysis and calculations of frequency characteristic have been done by using three-dimensional electromagnetic code, and the unique characteristics are analyzed and discussed in this paper.
