Electron beams with power density 106-109 W/cm2 are used for modification of the materials surface. The question of the transporting of high current low-energy beam in a low-pressure gas filled electro-dynamic system is of current interest. In this work there is presented a model and there has been conducted theoretical research of the plasma channel forming under the low-energy beam transporting in low-pressure air in an external magnetic field. There has been shown the magnetic field influence on the plasma channel parameters and the current neutralization of electron beam in dependence on the gas pressure and the drift tube geometry. The comparison with experimental data is conducted.
