Abstract

A dynamics of electrons is investigated within discharge of a stationary plasma engine taking into account their transfer across the magnetic field from a cathode region to anode. Obtained results show that the transfer is caused at least by three mechanisms. The first of them is a negative gradient of the field acting after the exhaust engine exit, the second is a positive gradient of electron pressure acting in the anode region of the discharge. The third cause is an electron friction against the walls of a discharge chamber. It is determined by the electric field influence. When the transfer occurs some plasma oscillations are excited in microwave band as well as in high and low frequency bands. The results of the modeling are compared with corresponding experimental data and fit them satisfactorily.
