摘要
该文利用线性理论,对相对论环形电子注与环形等离子体互作用产生微波辐射进行了研究。在考虑有限磁场的基础上,利用“匹配场法”求得色散方程。重点分析了等离子体密度、厚度,外加磁场对等离子体切伦可夫脉塞注-波互作用的影响,并计算了各参量变化时的波增长率以及色散关系。
Considering the effect of the longitudinal uniform magnetic field, the microwave radiation produced by the interaction of a relativistic electron beam with a annular plasma is examined by use of the linear theory. In this paper the 'applied field' approach is used to derive the dispersion relationship. Analyzed the different plasma density, position, thickness, and field intensity influence to the beam-wave interactions in plasma Cerenkov maser. Finally, the curves and dispersion relationships about every parameter to influence the increase rates of linear space are given out.
