| 摘 要： | 曙光一号自由电子激光装置用自发辐射放大(ASE)机理,在毫米波波段测得了数百毫瓦的光信号输出。利用三维WAGFEL程序,结合曙光一号直线感应加速器型自由电子激光放大器参数,详细地分析了自发辐射放大的增益、输出功率随电子束的质量(包括束流能散度、流强、发射度等因素)的变化情况,给出了相应的定标关系;并且考察了摇摆场随机误差对自发辐射放大功率的影响。最后对自发辐射放大的实验结果进行了分析。

| Abstract: | Based on SG-1 LIA FEL amplifier parameters, the ASE output power and gain, as well as their relationship with electron beam quantity including beam energy spread, emittance, and beam intensity etc.are simulated and analysed by using 3-D WAGFEL code. The related scaling law has been given. Mearwhile the influence of the wiggler magnetic field's random errors on ASE output and the experimental results are also analysed. |
