Study of 220GHz Coaxial Cavity Gyrotron

同轴谐振腔是目前有望提高电子效率的方法之一,在圆柱腔中加入内导体轴,可以使工作模附近的模谱变稀,有利于模式选择,抑制模式竞争,并有利于电子束的降压回收。通过对同轴波导进行理论研究。分析了各种参数时其的影响,并用计算机编程进行数值分析,最终得出了理论上电子效率可以达到40%以上的同轴腔体结构的结论。

The coaxial-cavity is one of the hopeful method raising the electronics efficiency at present, joining the inside conductor axle in the cylinder cavity makes the pattern register nearby work pattern becomes rare and to be of advantage of the model selection, restrain the model competition and recovery electron beam to step-down easily. This text is studied by carrying on theoretical research to the coaxial waveguide, analysed the influence of various parameters, and drawed out the direct picture by computer ranging.This text is carrying on theoretical research to the coaxial waveguide, and analysed the influence of various parameters,and carries on the numerical analysis in the computer, and finally gained a coaxial cavity body structure which the electronics efficiency can achieve more than 40% in theory.
