大轨道电子注 非线性理论 电子注偏心 回旋返波振荡 large-orbit electron beam nonlinear theory misaligned electron beam gyro-backward wave oscillation
摘要
建立了大轨道电子注回旋行波放大器的非线性理论,并考虑了电子注偏心时的情况.利用该理论分别研究了大轨道电子注偏心对工作模式和返波振荡模式的影响.结果表明,对于工作模式,偏心导致放大器的平均单位长度增益下降,而对于返波振荡模式来说,偏心导致了可能存在的振荡模式发生变化,使得大轨道电子注偏心时的模式竞争更加复杂.
Abstract
The nonlinear theory of large-orbit gyrotron traveling wave amplifier (gyro-TWA) was developed with consideration of misaligned electron beam. The effects of misaligned electron beam on both working mode and backward oscillation mode were studied using this theory. The results show that, for working mode, the average gain is decreased by the effect of misalignment, while for backward oscillation mode, the misalignment leads to changes of possible oscillation modes which makes the mode competition in large-orbit misaligned electron beam is more complex.
