| 摘 要： | 研究了离子通道回旋电子束脉塞（ICECM）中的等离子体波非线性效应。利用流体理论与自洽非线性理论方法对ICECM中等离子体波效应的微观机理进行了分析。研究发现，等离子体波加强了电子束的纵向群聚，束-波互作用的能量交换效率及系统增益得到明显提高。数值模拟计算表明，对于中等等离子体密度、1.5kA电流和1MV加速电压的电子束，系统能够获得的脉冲功率和频率分别为200MW和280GHz的毫米波束。

| Abstract: | The plasma wave nonlinear effect of Ion Channel Electron Cyclotron Maser (ICECM) is investigated. Using these methods of fluid theory and self nonlinear theory, the micro mechanism in ICECM are analyzed. Studies find that the longitudinal focus is intensified and the beam wave interact efficiency is remarkably increased. Numerical calculations show that , for middle ion density and the electron beam of 1.5kA and 1MV, the scattering wave frequency and the output power in ICECM system can achieve 280GHz and 200MW respectively. |
