For a quantitative validation of the nonlocal approach for simulation of positive column of dc gas discharge in neon, we have performed a comparative self-consistent calculations of parameters of longitudinally uniform positive column using two approaches—a full kinetic equation with a radially inhomogeneous electron distribution function (exact calculation) and a nonlocal approach. The calculations were performed for discharge current 1 mA and neon pressures 40 and 90 Pa. It is shown that discrepancies between parameters calculated with the two approaches—radial distributions of electron number densities, ionization rates, space potentials—are minor. Physical reasons of a validity of the nonlocal approach for present conditions are discussed.
