| 摘 要： | 本文综述了几种在迴旋管中采用大横截面谐振腔的办法,计算了中等偏心率椭圆波导各TE模的归一化截止频率。归一化截止频率的数据表明,用椭圆横截面谐振腔的迴旋管具备以下特性:(1)谐振腔体积大;(2)可以振荡的工作模式少;(3)可以使用大直径电子束;(4)可以工作于低次角向腔模。

| Abstract: | In this paper, several types of resonant cavities with large transverse cross-section used in gyrotron are briefly reviewed. The method of caleulating the cutoff frequeneies of TE mode of elliptical waveguides with moderate eccentricities is given. From the cal-culated data of cutoff frequencies, it is shown that the gyrotron with elliptical cavity has the following characteristics: (1) a large volume cavity can be used; (2) the dcn-sity of modes which can oscillate is rare; (3) it is allowable to use an electron beam with a large diameter; (4) it is possible to use a cavity mode with low azimuthal number. |
