摘要 分析了基于同轴静磁波荡器的自由电子激光中,电子束电流对辐射频率、辐射功率和所需的束波互作用腔长度等参数的影响规律,研究了该类型自由电子激光中的电子束平均半径、波荡器磁感应强度等参数的选取原则,分析了束波互作用腔及其输出结构的设计方法。设计了辐射频率为107GHz的基于同轴静磁波荡器的自由电子激光,获得了辐射功率为35 MW的TE01模。 The influence of electron beam current on radiation frequency,power and length of the beam-wave interaction area in a free electron laser based on coaxial static magnetic undulators were discussed.The average radius of the electron beam and the strength of the magnetic field of the undulator for stable transmission were calculated,and the design method of beam-wave interaction cavity was studied.A coaxial static magnetic free electron laser at 107 GHz was designed and simulated with PIC,and the radiation power of the TE01 mode of 35 MW was achieved.
