“…Under these circumstances, a whole new realm of transport data opens, that involves the cross‐sections for excited states (stepwise excitation, stepwise ionization, etc.). Not surprisingly first important applications involved modeling of CO 2 lasers, but also hydrogen discharges and nitrogen containing discharges . Perhaps the widest and the simplest similar modeling is that involving properties of discharges in rare gases with a large abundance of metastables in particular in argon .…”

In this review, several examples of ionized gases are presented where swarm models may be employed to provide full description. Those situations include low space charge pre‐breakdown, Townsend region breakdown where space charge effects may be calculated from the swarm model and used as the first order perturbation to describe oscillations and transient signal and afterglows. In addition, implications are considered for microdischarges, discharges in and close to liquids, gas‐filled particle traps, thermalization of particles in living tissue, and many more. In all those situations, swarm models provide full description of the discharge, while for most other collision dominated non‐equilibrium plasmas swarm physics (transport‐related phenomena) provides a part of the foundation of modeling.

This article reviews a variety of methods to obtain the electron temperature and density by the emission line ratios for low-temperature plasmas containing argon or nitrogen gas. Based on the collisional–radiative model of excited particles, the underlying principle of each of these methods is described, along with the criterion on how to select an appropriate line-ratio method according to the discharge conditions. Limitations on the application of each line-ratio technique are also discussed.

Helium glow discharges in the p = 6-60 mbar pressure range have been investigated experimentally and by means of a one-dimensional self-consistent hybrid model. Unlike most of the hybrid models developed previously for noble gas discharges, our model also includes He + 2 molecular ions. The electrical parameters of the discharges, recorded in the experiments, as well as the electron temperature for the different discharge conditions (determined spectroscopically) have been used as input data for the hybrid model. Our studies show that He + 2 ions are present in the discharge even at 6 mbar with a concentration comparable to that of He + ions. Conversion of atomic to molecular ions and the associative ionization process are identified as main sources of molecular ions. At low pressures the He + 2 ions are principally lost at the electrodes, while at higher pressures the recombination processes become their dominant losses. As the rates of recombination processes are strongly pressure-dependent, the optical emission spectrum changes with increasing pressure and shows significant intensity of He 2 molecular bands. The contribution of He + 2 ions to the ion current at the cathode as well as their contribution to maintenance of the discharge is found to be around 10%, even at the lowest pressure of 6 mbar, where He + 2 formation in most of the discharge models is neglected.
