Raman型自由电子激光中暖束效应的简化分析

Simplified Analysis of Warm Beam Effects for the Free Electron Laser Operating in Raman Regime

采用一维流体理论导出了暖电子束条件下Raman型自由电子激光增益的解析式。此式清晰地描述了自由电子激光中的暖束效应。分析计算时毋需电子分布函数的具体形式 。

This paper presents an analytical expression for the gain of the Free Electron Laser Operating in Raman Regime with a warm electron beam through the approach of one dimensional magnetohydrodynamics. Based on this expression, warm beam effects are demonstrated explicitly and universally regardless of any specific distribution function of the electrons.
