For a cyclotron resonance maser (CRM) with a helical axis-encircling electron beam, the possibility of a strong interaction between cutoff (gyrotron) and traveling Doppler-up-shifted (cyclotron autoresonance maser) modes, which are in resonance with the electrons at the same frequency, is demonstrated. This effect can be used in a CRM oscillator of a new type, where the feedback and the mode selectivity for the operating traveling mode are provided due to the excitation of the cutoff mode. According to both the theory and the experiment, such a scheme can provide an effective excitation of the traveling mode with negligibly low losses associated with the cutoff mode.
对于具有螺旋环绕电子束的回旋共振脉塞（CRM），证明了截止（回旋管）模式与传播的多普勒上移（回旋自共振脉塞）模式之间存在强相互作用的可能性，这两种模式与电子在相同频率下共振。这种效应可用于新型CRM振荡器，其中由于截止模式的激发，为工作传播模式提供了反馈和模式选择性。根据理论和实验，这样的方案可以有效地激发传播模式，同时与截止模式相关的损耗可忽略不计。
