“…Steady state Townsend (SST) discharges usually operating in self-sustained regimes (sometimes even the non-selfsustained regime was used- Urošević et al (1983)) have been used in order to obtain the excitation and ionization coefficients for a wide range of gases (Bulos and Phelps 1976, Lawton and Phelps 1978, Tachibana and Phelps 1981, Yamabe and Phelps 1983, Buckman and Phelps 1985, Nikitović et al 2007. One should be warned that conversion of SST data to cross sections also involves a more sophisticated theoretical interpretation than the standard time of flight (TOF) data (Sakai et al 1977, Boeuf and Marode 1984, Robson 1991.…”

“…Scattering cross sections and relevant transport data for ions at high energies and fast neutrals have been presented by Phelps for H 2 (Phelps 1992, Phelps 2006, Ar (Phelps 1991(Phelps , 1992(Phelps , 1994, N 2 (Phelps 1991), CH 4 (Petrović and Phelps 2006) and rare gases (Phelps et al 2000, Nikitović 2006, Nikitović et al 2007. A particularly strong effect of fast neutrals is observed in mixtures of rare gases and hydrogen (or methane) since the threshold for heavy particle excitation of hydrogen atoms is very low (Petrović and Phelps 1991).…”

In this review paper, we discuss the current status of the physics of charged particle swarms, mainly electrons, having plasma modelling in mind. The measurements of the swarm coefficients and the availability of the data are briefly discussed. We try to give a summary of the past ten years and cite the main reviews and databases, which store the majority of the earlier work. The need for reinitiating the swarm experiments and where and how those would be useful is pointed out. We also add some guidance on how to find information on ions and fast neutrals. Most space is devoted to interpretation of transport data, analysis of kinetic phenomena, and accuracy of calculation and proper use of transport data in plasma models. We have tried to show which aspects of kinetic theory developed for swarm physics and which segments of data would be important for further improvement of plasma models. Finally, several examples are given where actual models are mostly based on the physics of swarms and those include Townsend discharges, afterglows, breakdown and some atmospheric phenomena. Finally we stress that, while complex, some of the results from the kinetic theory of swarms and the related phenomenology must be used either to test the plasma models or even to bring in new physics or higher accuracy and reliability to the models.

“…Another limitation of all Monte Carlo codes mentioned here and in other related applications is that tests of the codes against the standard swarm benchmarks have not been made [2,3,6]; they sometimes use poorly defined quantities to compare with, such as trajectories or ranges, and do not include recently explained kinetic phenomena [16][17][18][19][20][21] which have often been found to be related to temporal relaxation, non-conservative processes or to non-hydrodynamic processes [22]. Properly defined transport coefficients [23,24] and tests against the standard benchmarks are the best way to verify the code for modeling the collision dominated transport of charged particles in gases.…”

We have performed simulations of electron thermalization in pure nitrogen under conditions that correspond to the upper layers of the earth's atmosphere. As opposed to the results from the literature we have shown that it is necessary to include multiple excitations due to secondary electrons. We have also shown that direct calculations may be achieved very accurately without limiting them to the maximum range though it may be a useful concept for modeling of experiments. The present data may be used as a basis for modeling of the entry of high energy cosmic rays into the atmosphere, for studies of the initiation of lightning discharges in the upper atmosphere including auxiliary phenomena such as sprites and elves and for modeling of the laboratory discharges at high E/N. The connection is made even more relevant through normalization of the cross section data to the swarm data.
