| 摘 要： | 研究了用磁场增强摇摆器来提高自由电子激光器效率的机制．采用KMR方程，考虑空间电荷效应，模拟计算发现自由电子激光器的效率有了很大的提高，而且电子束能散度越大，对提高自由电子激光器效率越有帮助．因此采用磁场增强摇摆器能充分利用加速器的能量来莸得更高的自由电子激光器能量

| Abstract: | FEL efficiency improvement with magnetic field increasing wiggler has been- investigated.-Numerical simulation with KMR equations considering space charge effect we find that FEL power increase greatly.It is interested that the larger the energy spread is,the greater the FEL power increasement is.Therefore the-whole electron beam of the accelerator can be used for FEL and higher power can be gotten with magnetic field increasing wiggler. |
