Features of development of the beam-plasma discharge in high pressure gas and prospects of its use G. P. Berezina, V. S. Us National Science Centre "Kharkov Institute of Physics and Technology", 1 Akademicheskaya str., Kharkov, 61108, Ukraine E-mail: berezina@kipt.kharkov.ua Dynamics of the stationary beam-plasma discharge at the 10-3—1 Torr pressure of neutral gas was studied. <...> Three regimes of the discharge were found, two of which are different on properties, have novelty, and not investigated earlier. <...> Generation of ion streams was investigated, and experiments on "dry" clearing of surface of metal samples by them have been carried out. <...> Areas of pressure in which the discharge can effectively be used for nonequilibrium plasma chemistry have been determined. <...> PACS: 52.35.-g; 57.77.Fv Keywords: beam-plasma discharge, beam-plasma instability, dissipative instability, nonequilibrium plasma chemistry. <...> Выделены три режима разряда, два из которых по свойствам отличаются новизной и ранее не исследованы. <...> Указаны области давлений нейтрального газа, в которых разряд может эффективно использоваться для неравновесной плазмохимии! <...>
