摘　　要：用随机数构造了摇摆器磁场的误差分布．基于CAEPFEL的理论设计，研究了磁场误差对自由电子激光器增益的影响．Based on assumption of wiggler field errors as a set of uniform random numbers,the effects of wiggler field errors on the gain in CAEP FIR FEL are studied.The maximum allowable wiggler field error(peak to peak) is about 2%.It is found that the effects of wigg1er field error on the nonsteady-state gain are almost as the same as that of steady-state gain.

关 键 词：自由电子激光 磁场误差 增益 非定态 激光器
