The behavior of electron-ion ensemble accelerated in the diode is studied. Hot electrons are described by means of the distribution function which is a solution of the collisionless kinetic function depending not only from integrals of motion. To describe the cold ions the hydrodynamics equations are used. The possibility of the ion-sound velocity excess of the ions is shown. The expression for the electron gas pressure is received. The dependence of relative density of the ions on the coordinate is discussed in the case of closed phase trajectories.

The behavior of relativistic intense electron beam with elliptical cross-section moving in a longitudinal magnetic field is investigated with the help of self-consistent model. The solutions for the beam envelopes are obtained in the case of the beam current differed from Alfven limit and the beam charge neutralized. The conditions of stationary beam propagation are determined, however it is discovered that for the case of non-zero self-consistent magnetic field the stationary beam propagation is violated, the partial emittance oscillations being observed. The found time- dependence of the partial emittances and the beam envelopes illustrates the effect of emittance transfer caused by the coupled particle motion in magnetic field.
