摘要
用新的３－ＤＨＧＦＥＬ程序分别计算分析了无限长、有限长和短电子束微脉冲产生的自由电子激光的特性。在前两种情况下得到的结果与原有的３－ＤＯＳＩＦＥＬ程序计算得到的结果符合较好，而３－ＤＨＧＦＥＬ程序所用机时可大大缩短。在后一种情况下初步计算分析了北京自由电子激光器的光场演化特性。
In this paper,we computed and analyzed behavior of FEL gener-ated for infinite, finite and short micropulse of electron beam by 3-D HGFEL code that we developed recently. Results obtained for the first two cases coincide with not only those obtained by 3-D OSIFEL code, but CPU time spent by 3-D HGFEL code is much less than that by 3-D OSIFEL code. We preliminarily computed and analyzed the evolution of Beijing FEL optical pulses for the last case.
