同轴腔自由电子回旋脉塞的输出功率
-
摘要: 介绍了同轴腔自由电子回旋脉塞输出功率受电子束错位的影响,并就德国卡鲁斯研究中心(FZK)正在建造的波长为2mm、输出功率为1.5MW的同轴腔回旋脉塞,进行了数值计算分析。结果表明:电子束错位会使输出功率下降,但对工作模TE82,16,1模的影响,比对竞争模TE27,16,1模的影响更小。Abstract: The influence of the electronbeam misalignment on the output power ofa coaxial cavity freeelectron maser isinvestigated,and numerical analysis iscarried out to the device which is beingconstructed in FZK of Germany.Resultsshow that the electronbeam misalignmentsubstantially decreases the output power,but has less influence on the operatingmode TE28,16,1 than on the competitionmode TE27,16,1.
