Abstract

Analytic model for estimating main parameters of the shot glow discharges is presented. Proposed model takes into account as the electrons production in cathode sheath as nonlocal ionization in the negative glow plasma. According the traditional approach, discharge is dividing on different areas by means visual analysis. Discharge gap is dividing on volume charge sheath and quasi-neutral plasma in presented model. Plasmas areas comprise negative glow, Faraday dark space and positive column. Simple expressions for main glow discharge characteristics (voltagecurrent characteristic, cathode sheath) as well as plasmas density profile without volume recombination are deduced. Finding results satisfactorily correspond to the experimental data. Traditional Enghel – Shteenbek model (witch founded on local approach) gives more considerable disar[1]rangement with experiment.
