The electron transport of air in a uniform electric field is investigated by a Monte-Carlo simulation. The simulation results obtained are compared with the available data in the literature. The result of Monte-Carlo simulation shows that electron molecule collision cross sections adopted in the simulation result in good agreement with the experimental values over the range of E/N investigated (E is the electric field and N is the gas number density of background gas molecules).

There has been considerable interest in non-thermal discharges over the past decade due to the increased number of industrial applications. The properties of discharges in electronegative gases are most frequently used for technological applications. For the improvement of performance in these applications, it is necessary to understand discharge dynamics experimentally and numerically. In this paper, a Monte Carlo simulation is carried out in sulfur hexafluoride (SF6) in uniform electric fields. The streamer propagation, electron, positive and negative ion distributions and space charge fields are studied in detail as time increases.
