自由电子激光的粒子模拟

The Particle Simulation of Free Electron Laser

文中简单介绍了自由电子激光粒子模拟方法,用■维完全相对论性电磁模程序模拟了相对论电子束通过回旋磁场产生电磁辐射的过程,并作了理论解释;研究了纵向引导磁场对能量转换效率的影响。

The paper briefly describes the method of particle simulation of a freeelectron laser. By passing a relativistic electron beam over a rippled static-magnetic field, high frequency electromagnetic radiation is generated. Thisprocess is simulated through a one and two-halves fully relativistic electroma-gnetic program. Some relevant theoretical explanations are also represented. Theinfluence of the axial guide magnetic field on the saturation energy conversionefficiency is studied.
