带轴向引导磁场自由电子激光的单粒子哈密顿理论

The Single-Particle Hamiltonian Theory of a Free-electron Laser with An Axial-guide Magnetic Field

在Ｂａｍｂｉｎｉ－Ｒｅｎｉｅｒｉ坐标系中给出了带轴向引导磁场自由电子激光的单粒子哈密顿形式．得到了轴向场对器件增益放大系数的表达式，并讨论了对轴向场取值的一些限制条件．

The Single-particle Hamiltonian theory is given for a free-electron laser with an axial-guide magnetic field in the Bambini-Renieri frame.The expression of the amplifying coefficient of the axial-field is obtained and the constraints on the value of the axial-field are discussed.
