采用PIC模拟方法对同轴混合铁磁摇摆器自由电子激光器进行了研究,分析了等离子体填充对其性能的影响。粒子模拟结果表明,这种同轴摇摆器结构FEL在工作电压较低(205 kV)的情况下仍可以得到较好的放大输出,效率达到27.3%,饱和功率达到兆瓦级;等离子体填充对器件的性能有一定的影响,改善了束流传输特性。
关 键 词 等离子体; 自由电子激光; 摇摆器; 粒子模拟
Abstract A coaxial hybrid wiggler free-electron laser(FEL) amplifier with and without plasma filling is studied by a method of PIC simulation in this paper. The results show that signal in FEL amplifier with a coaxial hybrid wiggler can get an efficient amplification even at a low voltage of 205 kV. The efficiency of the amplifier is upto 27.5% and the saturation power arrives to a MW level. Plasma has some beneficial effects on the characteristics of the FEL amplifier, for example, it can improve the characteristic of electron beam transmission.
