摘要
本文对无栅间隙双重入圆柱型同轴谐振腔的TM310模的场分布进行了研究。对无栅间隙双重入同轴腔中TM310模的场分布进行理论分析,得到最佳注波互作用的漂移管设置方式和高阶模TM310模场分布稳定的同轴腔结构,同时分析了电感调谐膜片影响TM310模场分布均匀性的原因。并利用三维电磁场软件对一个电感调谐同轴腔进行了数值模拟,研究了调谐膜片与外腔壁距离变化时,谐振腔内TM310模场分布的变化规律,得到了调谐膜片离原腔壁越近,场分布越均匀的结论。
The field distributions of the TM310 mode in the double reentmnt cylindrical coaxial cavity with non-grid- ded gap were calculated with the CST software package. First, the transmitting tubes are set in such a manner that the best beam-wave interaction can be realized; and the coaxial cavity is constructed in such a way that the steadiest field distribution of high-order mode of TM310 can be obtained. Next, the influence of the inductive tuners on the uniformity of the field distribution involved was also evaluated. Finally, the coaxial cavity with single inductive tuner was simulated with CST software in 3D electromagnetic codes. Having evaluated how the variations in the separation between the inductive tuner and the outer cavity wall affects the field distribution, we conclude that the smaller the separation, the more uniform the field distribution.
