| Abstract: | The dynamics of a relativistic electron was investigated in a constant-amplitude helical undulator with a uniform axial magnetic field.The trajectory of an electron as well as its projection on the transverse plane was investigated by means of numerical simulation.In the cases where the electron was not injected along an ideal helical trajectory,the projection of electron trajectories along the undulator was discussed,and the criterion for periodic or quasi-periodic is provided. |
