   The physics-mathematical model of acceleration gap of intensive electronic beam which take into account ionization processes and mobility of emitting surface of plasma was suggested. The developed algorithm of calculation of electron-optical systems with the plasma emitter was realized in the programs of numerical simulation of conditions of formation of narrow and tubular electron beams. Numerical simulation has shown, that ionization processes can both positive and negative influences on formation and characteristics of electron beam.
