摘要
把变参数自由电子激光器的电子纵向运动方程化为具有外力矩的摆方程,并将它同加速器和沟道辐射类比,讨论了系统的相平面特征以及饱和性和临界状态等。导出了系统的增益公式。
In this paper the longitudinal equation of a electron in FEL with a variable parameterhas been reduced to a pendulum equation with applied moment, and it has compared to theaccelerator and the channeling radiation. The property of the phase plane, the saturationand the critical condition have been described, gain equation has been drived also.
