抑制径向速调管高次杂模振荡的方法

摘要

速调管中高次模振荡会严重影响工作模式的束波互作用,降低速调管的效率,因此,抑制杂模在径向相对论速调管的设计中非常重要.文中针对刻槽谐振腔的场分布,提出了利用磁耦合环降低非工作模式Q值的方法抑制杂模振荡,并利用时域仿真软件进行模拟验证.%High-order mode oscillation in klystron seriously affects the working mode of beam-wave interaction,reduces the efficiency of klystron.Therefore,the suppression of high-order mode oscillation in the design of radial relativistic klystron is very important.Aimat large radius of the coaxial cavity field distribution,this paper uses magnetic coupling ring to reduce the high-order mode Q value and its suppression.The last,by using time domain simulation software it simulates test and verification.
