【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。更多还原

【Abstract】 Ampliher experiments of SG-1 FELs with the 0.26T wiggler field and3.3±0.15MeV,～600A electron beam have generated the peak microwave power of 10MW and about 19dB/mgain。But it has been no saturation。 In this paper,well analyze the experimental results of SG一1 FELs and discuss the some problenls of SG一1 FELs experiments,then offer our some improvable methods.更多还原
