In the work an injection of high-current electron and ion beams in a drift gap of the linear induction accelerator with collective focusing is studied. Consideration is carried out by means of numerical simulation by PIC-method in frame of full Vlasov-Maxwell equations set. It is shown, that a filling of a drift gap with the dense electron cloud, which is confined by magnetic field of trap configuration, on the one hand, provides charge compensation. However, on the other hand, it promotes development of electron and ion beams instability. Parameters (cloud density and temperature) and conditions, at which the energy spread of pulsed high-current (the density of particles 7·10¹⁷ m⁻³) ion beam does not exceed several percent are chosen.
