Abstract:
Monte Carlo (MC) calculations of transport and rate coefficients of an electron swarm moving in nitrous oxide (N2O) under the influence of DC crossed electric and magnetic orthogonal configuration fields are presented. The set of cross sections for e-/N2O interaction obtained in our previous investigations was used as the initial parameter. Calculations of mean energy, drift velocity, diffusion coefficients and rate coefficients for elastic and individual inelastic processes were performed for five different values of reduced magnetic field (B/N = 100 Hx, 200 Hx, 500 Hx, 1000 Hx and 2000 Hx, (1Hx = 10-27 Tm3), where for each of these values, the value of the reduced electric field (E/N) varied in the range from 50 Td to 2000 Td (1Td = 10-21Vm2). The ratio of the cyclotron to total collision frequency in these cases is less than one for all values of B/N (except for the highest one when it is slightly greater than one), so we may suggest that electrons are in a collision-dominated mode. The cooling effect of the swarm is visible, i.e. there is a decrease in its mean energy as the magnetic field increases, as well as a decrease in the drift velocity component in the electric field direction. Electron diffusion is slightly anisotropic for the higher values of B/N.
