Abstract
The article presents the study of the pulsed electron beam propagation in oxygen and nitrogen. The researches were performed using the TEA-500 pulsed electron accelerator and drift tube. Parameters of the TEA-500 pulsed electron accelerator are as follows: the electron energy (varies) is 200-450 keV, the beam current is 10 kA, the half-amplitude current pulse duration is 60 ns, the pulse repetition rate is up to 10 Hz (in the pulse burst). The accelerator is equipped with the necessary means of diagnostics of the beam parameters: particle energy, current and current density, the total energy transferred by the beam. The drift tube includes a chamber consisting of two sections of reverse current shunts located along the entire length of the drift tube. The following precursors used N2 and O2. The specified types of gases were chosen as they are among the main components of the flue gases, whose treatment has been widely reported recently.

Oscillograms of characteristic currents (the electron current closing on the walls of the first section of drift tube (1), the electron current closed on the walls of the second section of drift tube (2), the electron current reaching the back flange of drift tube (3), and the total reverse current closed on the walls of drift tube (4)) of oxygen at different pressures are shown in figure 3
The work has presented the research results on the pulsed electron beam propagating in oxygen and nitrogen under 50, 300, and 760 Torr pressures in the drift tube
Summary
Acute problem of ecology is pollution of atmospheric air. The enterprises of ferrous and non-ferrous metallurgy, chemistry and petrochemistry, construction industry, energy, and fuel industry affect the air pollution. An alternative to the above-described process for low-power enterprises may be the organization of plasma-chemical binding of harmful components of flue gases with the initiation of the process by a pulsed electron beam [13,14].
