摘要: 利用自洽线性场理论,普遍讨论了扰动电磁场作用下的电子三维扰动,然后就介质切伦可夫脉塞中常用的两种相对论电子注,即环形相对论电子注和实心相对论电子注的注波互作用进行了详细的分析,分别导出了对应于这两种相对论电子注的注波互作用色散方程,并求得了波增长率,计算和分析了这两种相对论电子注的半径对互作用波增长率的影响.本文的工作为此类器件的工程设计提供了一定的理论依据.

关键词: 环形, 相对论电子注, 电子三维扰动, 波增长率, 实心, 介质切伦可夫脉塞

Abstract: Making use of the self-consistent linear field theory, the three-dimensional perturbation of electrons affected by the perturbed electromagnetic fields is generally discussed. The interactions of wave to the two conventional relativistic electron beams in the dielectric Cherenkov maser, i.e., annular electron beam and solid electron beam, are analyzed in detail. The dispersion equations and the wave growth rates corresponding to the two relativistic electron beams are derived.The effects of the radii of the two electron beams on the wave growth rates are calculated, and the discussions are presented.

Key words: relativistic electron beam, three-dimensional pertu rbation of electron, wave growth rate, dielectric Cherenkov maser, annular, solid
