| 摘 要： | 研究了波荡器磁场增强对提高自由电子激光器效率的影响。模拟计算发现采用磁场增强波荡器能使自由电子激光器的效率提高到１７．６％，采用磁场预先增强而后又增弱的锥型波荡器则能获得高达４３．３￥的输出效率，自由电子激光器的功率得到进一步的提高。

A Tapered Wiggler with Pre}ncreased Magnetic Field |
| |
| Abstract: | The efficiency improvement of free electron laser (FEL) by increasing wiggler magnetic field is inverstigated. Numerical simulation shows that inereasing wiggler field can increase FEL efficiency from 12.9% of uniform wiggler to 17.6%. It is interesting that if the wiggler field is tapered after being increased, a FEL efficiency as high as 43.3% can be obtained. |
