We present a theoretical analysis of cyclotron resonance maser (CRM) operation at two resonant frequencies including the effects of momentum spread in the electron beam. A linear analysis of the system equations is presented in the limit of small momentum spreads. Numerical solutions to the system equations are also given and are in agreement with the linear theory. The results predict that for realistic momentum spreads, operation of the CRM at the higher of the two resonant frequencies should be possible, extending its operating frequency range. An experiment currently under development at Strathclyde University is described and modeled numerically.
我们对回旋共振脉塞(CRM)在两个共振频率下的运行进行了理论分析,其中包括电子束中动量扩散的影响。在小动量扩散的极限情况下,对系统方程进行了线性分析。还给出了系统方程的数值解,这些解与线性理论一致。结果预测,对于实际的动量扩散,CRM在两个共振频率中较高的那个频率下运行应该是可行的,从而扩展了其工作频率范围。描述了目前正在斯特拉斯克莱德大学开展的一项实验,并对其进行了数值模拟。
