摘　　要：自由电子激光(FEL)相比于传统激光最大的优点之一便是能够较大范围、连续调节输出激光的波长．通常,较大范围调节FEL波长的方法是调节电子束的能量．通过对BFEL进行大量的模拟计算, 重点讨论了其在保持电子束优良性能的前提下,大范围调节电子束能量的方法,包括:改变加速管的加速梯度、调整电子束的加速相位以及改变电子束的流强等．One of the advantages of free electron lasers (FEL) compared to the conventional laser is the possibility of changing the radiation wavelength in a wide range. However, a series of problems arise under the realization of this advantage. In this paper, the problems, related with the adjustment of energy of the BFEL linac, are investigated mainly with the method of simulation. Three adjustment means are discussed, including changing the gradient of accelerator section, the beam phase and the beam current.
