摘要
给出了描述回旋行波放大器中辐射场演化的方程组 ,对电子束的群聚做了详细的理论分析 ,推导出了辐射场小信号增益的解析表达式 ,并得到两点结论 :在小信号区 ,力群聚作用可超过惯性群聚作用而产生负增益 ;在一定条件下 ,轴向群聚和角向群聚这两种作用可以相互增强。
Self consistent equations for the beam wave interaction in the electron guiding center coordinate are derived. Two new conclusions are drawn by theoretical analysis: the axial bunching and azimuthal bunching can be reinforced in some cases; the effect of the force bunching may surpass the inertial bunching and generate a small gain dip in the small signal region. Theoretical analysis is verified by numerical simulation.
