SG-1 FEL放大器实验初步分析

THE INITIAL ANALYSIS OF AMPLIFIER EXPERIMEUTS OFSG 1 FEL

摘要: 在摇摆场0.26T,电子束能量3.3±0.15MeV,束流约600A时,SG-1FEL常参数放大器实验最大功率约10MW,指数增益约19dB/m。对实验进行了初步的分析讨论,并就实验时4m长摇摆器功率未呈饱和、指数增益区右移现象与下一轮实验的改进提出了意见。

Abstract: Amplifier experiments of SG-1 FELswith the O.26Twiggler field and 3.3±0.lsMeV，~60oAelectron beam have generated the peak microwave power of loMW and about l9dB/m gain. But it has been no saturation. In this paper,we'll analyze the experimental results ofSG-l FELsand discuss the someproblems of SG-lFELs experiments,then offer our some improvable methods.
