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.
