Drift-orbital resonance

The estimation of optimal parameters with the analytical model regarding nonlinear electron motion dynamics is fulfilled for the submillimeter-wave M-type oscillator tor operating on frequency about 0.33 THz with anode voltage 13 кV and magnetic field 0.7 Т. Revealing from this model, the magnetron interaction space geometry providing the effective electron interaction with a high-frequency field on (+1) spatial harmonic of π-mode oscillations is proposed for the drift-orbital resonance regime.

The analytical estimation of the optimal parameters fulfilled for pulsed magnetrons with cold  secondary-emission cathodes, operating at a frequency of 32 GHz with anode voltage of 8 kV and  with magnetic field of about 0.4 Tesla. As shown, the geometry of the magnetron interaction space  can ensure an interaction between electrons and the high-frequency field as for the (−1)-th space  harmonic of π/2-oscillations, so for (+1)- th space harmonic π-oscillations in the drift-orbit  resonance mode.
