Self-oscillations in a cyclotron maser with background plasma

The dynamics of a cyclotron maser is considered in a two-level approximation with nonlinear inertia saturation of absorption due to background plasma heating. The conditions of the existence of a self-oscillation mode in the presence of a permanent source of energetic particles in this system and a particle acceleration process in adiabatic magnetic compression of the plasma are specified. The self-oscillation characteristics are studied numerically as functions of the parameters of the system.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Radiofizika, Vol. 39, No. 8, pp. 988–1000, August, 1996.This work was supported in part by the Russian Foundation for Fundamental Research (Project Code No. 96-02-16473a).
