“…Light fluxes were recorded using the method of multichannel photon counting with a resolution of 40 ns or more. The afterglow duration under any conditions was enough to observe the change of the mechanism of the 2p 5 5s levels population from the excitation transfer at the early stage of plasma decay to recombination of atomic Ne + or molecular HeNe + and Ne 2+ ions with electrons [9,10]. The analysis of population levels was performed in the early afterglow, in which the intensities J(t) of the spectral lines of the 5s → 3p transitions fell identically to the density of the [He(2 1 S 0 )(t) atoms For registration of [He(2 1 S 0 )] we used the method absorption of the radiation of additional source on the line 501.6 nm In addition to the intensities of spectral lines J(t) we registered the afterglow spectra.…”

The results of a spectroscopic study and simulation of the processes of population and destruction of the levels of the 2p55s configuration of a neon atom in a decaying plasma of a low-frequency barrier discharge in a He-Ne mixture are presented. Experimental conditions: helium pressure 0.08-22 Torr, neon pressure ≤ 3 mTorr, electron density less than 1011 cm-3. On the basis of data on the evolution of the populations of the 3si levels (in Paschen's notation) with a change in helium pressure, data on the rate constants of collisional processes that determine the kinetics of these levels in He-Ne plasma are obtained more accurate than those available in the literature. Keywords: dielectric barrier discharge, helium-neon plasma, excitation transfer, afterglow, inelastic collisions.

The work is devoted to the study of the spatiotemporal dynamics of the production of excited atoms in an extended nanosecond discharge with a slot cathode in neon at medium gas pressures. The authors experimentally investigated the frame-by-frame dynamics of the spatiotemporal formation of the discharge optical irradiation with an exposure time of 5 ns and time intervals between frames of 2 ns. Under similar conditions, the concentration of excited neon atoms at metastable levels with a time resolution of about 10 ns was measured by laser absorption spectroscopy, and the current-voltage characteristics of the discharge were experimentally determined in a wide range of amplitudes of voltage pulses and gas pressures in the range of 1–60 Torr. To analyze the kinetic processes in the plasma source under study, numerical simulation of ionization processes in the Comsol Multiphysics software environment was performed using a special Plasma module.
