Analysis and computation of input cavity cyclotron wave protector

介绍了回旋波保护器的组成和工作过程,以及Cuccia谐振腔的结构优点。建立了电子束的运动方程,并给以合理的假设进行模型简化,得到运动方程在Cuccia谐振腔场情况下的解析解,以此为基础,得到了电子束能量转换最有效的条件(),以及横向位移与电场振幅之间的关系,从而分析出保护器工作机理。

This article represents the structure and operating principle of cyclotron wave protector and the advantage of the Cuccia coupler structure.the kinetic equation of electron beam is deduced.By virtue of the rational assumption ,the analytic solution to the equation is deduced.According to the solution ,the condition when the energy conversion of electron beam is most effective and the relation between amplitude of electric field and lateral displacement is obtained.Finally ,the working mechanism of cyclotron wave protector is clarified.
