摘要: 求解纵向摇摆器磁场加直流磁场中的电子运动方程,在直角坐标系中求得电子速度的严格解析解,并 导出直角坐标和圆柱坐标中电子位置坐标的近似解析解。同时用电子运动模拟计算进行了校验,指出近似解析 解有较好的准确性。Abstract: The motion equation of electrons in an axial uniform magnetic field and a longitudinal wiggler magnetic field is solved. The strict analytical solution of the electron velocity is derived in the rectangular coordinate system, and the approximate solutions of the electron position in the rectangular or cylindrical systems are also derived. The solutions are verified by numerical simulation, showing that the approximate solutions are fairly accurate.
