Self-organization of electron beams, interacting with a surface, in systems with crossed fields

The model of the secondary electrons nonstationary nonuniform emission in the crossed fields is developed. The problems on the beam dynamics in the crossed fields under the conditions of developing the nonuniform nonstationary self-sustaining secondary emission are discussed. The results of the self-organization numerical modeling by the electron fluxes azimuth under the condition of maintaining full capacity and complete pulse of the system are presented. It is shown that development of instability and origination of current leakage transverse to the magnetic field, exceeding the magnetic isolation critical field, is conditioned by existence of the feedback on the emitting surface
