This paper reports a detailed study of 90% Ne – 10% Ar gas mixture DC glow discharge at low pressure, wherein 15 chemical reactions are considered. The second-order fluid model is used. The parameters of particle transport and their rate coefficients strictly depend on mean electron energy. In the framework of the local electric field approximation, we have developed an analytical expression of the drift velocity of positive argon ions in a neon gas [Formula: see text], which is in good agreement with the experimental results, and serves to give best results than the results obtained using [Formula: see text] that exist in the literature. The results show that the argon ion density is more important than the neon ion density despite the presence of more constant background neon gas density in the mixture. The current density reaches 0.1729 mA/cm2 for 250 V applied potential under 2 Torr pressure in a gas mixture. The spatio-temporal evolution of both electric and energetic characteristics, as well as their spatial distribution in the steady state, are shown and discussed. The maximum value of the neon metastable atom density is 4.54957 × 108 cm−3, and for argon metastable atom density is 5.4689 × 108 cm−3. The model is verified experimentally and theoretically in the particular case.

The physical properties of Ne-Xe DC glow discharges at low pressure are reported for a gap length of 1 cm for the first time in the literature. The model deals specifically with the first three moments of Boltzmann's equation and includes the radiation processes and metastable atom densities. The spatio-temporal distributions of the electron and neon and xenon ion densities, the neon and xenon metastable atom densities, the electric potential and the electric field as well as the mean electron energy are presented at 1.5 Torr and 250 V. The current-voltage characteristic is shown at 3 Torr, and it is compared with previous work for pure neon gas. The model is validated theoretically and experimentally in the case of pure gas.

In this chapter an investigation of a DC argon and neon abnormal glow discharges with metastable atom density is presented. The values of pressure are between 133.32 and 330 Pa, and the voltage range is from 250 to 400 V in the case of argon gas. In the case of neon gas, the pressure has the value of 399.92 Pa (3 Torr) and the voltage ranges from 300 to 500 V. In the frameworks, an analysis of abnormal glow discharge characteristics is carried out in the case of input data taken from the Boltzmann equation in multi term approximation (BMA), and in the case of input data obtained from BOLISG+ code. As conclusion of these differences of input data in the same gas the output results are different and it appears in the cathodic region. The spatiotemporal distributions of electron and ion densities, the potential and electric field, the mean electron energy and the metastable atom density are shown. A 1D fluid model is used to solve self-consistently the first three moments of the Boltzmann's equation coupled with the Poisson's equation. Our results are validated with those obtained by both recent paper and experimental results.
