| 摘 要： | 在无引导磁场的作用下，利用自洽线性场理论，分析了电子的三维扰动速度和三维扰动电流密度对填充等离子体的介质切伦可夫脉塞注波互作用的影响，导出了注波互作用的色散关系和同步条件，所得关系清楚地表明，其工作用不稳定性是由填充等离子体的介质筒慢波波导中的ＴＭ模与电子注模通过电子注耦合所致，并求得了电子注引起的频偏和波的增长率。

| Abstract: | The effed Of three-dimensional perturbed velocities and three-dimensional perturbed current densities on the beam-wave interaction of plasma-filled dielectric Cherenkov maser is analysed by use of the self-consistent linear field theory without considering the effect Of the longitudinal guided magnetic field.The dispersion relation and the Simultaneous condition of the beam-wave interaction are derived. It is clearly shown that the instability of the interaction results from the coupling of the TM mode in the plasmafilled, dielectric lined slow-wave waveguide to the beam mode via the electron beam from the relations offered in this paper. Finally, the frequeney shift produced by the electron beam and the growth rate of the wave are obtained. |
