摘要
本文用磁流体理论研究了双电子束在圆波导中激发微波辐射的物理机制。在加有无限大引导磁场的情况下,导出了相互作用过程的色散关系,并在Cerenkov共振点ω=Κν_(α0)附近求出了最大增长率的表达式,简要地讨论了增长率与有关参量的依赖关系。
A fluid model is used to investigate microwaves excited by two REBs in a cylindrical waveguide. The dispersion relation is derived in the presence of an infinite axial magnetic field. The growth rate is given at the Cerenkov resonant point, and the results are discussed.
