摘要
本文使用1(2/2)维电磁相对论粒子程序对自由电子激光进行计算机模拟。在线性段,计算机模拟与用解析理论计算的增长率符合很好。与没有轴向引导磁场的自由电子激光相比,加一弱轴向引导磁场时,Wiggler场的强度可降得较低。加一强轴向引导磁场时,波能量达到饱和水平所需时间较短。
In this paper, the numerical results of particle simulation are presented for free electron lasers(FEL). A one and two half dimensional relativistic electromagnetic particle code is used. In linear region,the growth rates from numerical simulation are in good agreement with that from analytical theory. Effects of an axial guiding magnetic field on FEL and nonlinear behaviour of FEL were studied by the numerical simulation.
