摘要
基于分布作用速调管的工作原理和三维仿真模拟研究了双间隙及三间隙耦合输出腔的工作特性。以X波段为例,分别设计并确定了重叠模工作的双间隙输出腔和三间隙输出腔的结构参数,模拟计算了其群时延特性及场型。通过优化,在输出功率达1MW的情况下,三间隙重叠模输出电路可以达到10%的瞬时带宽。
Based on the theory of extended interaction klystron and three-dimensional simulation, the working characteristics in the double gap and three gap coupling output cavities were analyzed respectively. As an example, we designed the structural parameters of the double-gap and the three-gap coupling output cavities, and calculated the group delay characteristics and the field distribution,the results show 10% of the instantaneous bandwidth can respectively be reached for three gap overlapping mode output circuits at 1MW output power level.
