抑制径向速调管高次杂模振荡的方法

The way of high-order mode oscillation suppression in radial klystron amplifier

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.
