相对论电子注与等离子体柱互作用产生微波辐射的研究

Study of Microwave Radiation Produced by the Interaction of a Relativistic Electron Beam with a Plasma Column

本文利用线性理论，对相对论电子注与等离子体柱互作用产生微波辐射进行了研究，且考虑了纵向均匀磁场的作用．研究表明，由于纵向均匀磁场的作用，互作用在等离子体柱中产生的Ｅ模和Ｈ模场相互耦合而不可区分；导出了去耦合条件和去耦合下的Ｅ模色散方程，并对其进行了详细的计算和分析．

Considering the effect of the longitudinal uniform magnetic field,the microwave radiation produced by the interaction of a relativistic electron beam with a plasma column is examinned by use of the linear theory. It' s shown that the E-mode and the Hmode produced by the interaction in the plasma column are coupled and undistinguished because of the effect of the longitudinal uniform magnetic field. The uncoupled condition of the E-mode with the H-mode and the dispersion equation of the E-mode are derived. And the calculations and discussions of the dispersion equation are presented.
