“…There is considerable interest in swarm data for both carbon dioxide and nitrogen because of their current use in high power lasers as mixtures of COZ, NZ and He. When modelling such lasers it is necessary to know the mechanisms for energy loss in uniform electric fields especially for vibrational excitation (Lowke et aE 1973, Lakshminarasimha et aZl976, Limbeek andLucas 1978).…”

The Monte Carlo technique has been used to simulate the electron swarm motion in carbon dioxide and nitrogen, and electron swarm parameters have been evaluated in the range of E/N varying from 14 to 3000 Td (1 Td=10-17 V cm2). These parameters, namely ionisation coefficient, drift velocity, ratios of both radial and longitudinal diffusion coefficients, to mobility (also attachment and dissociation coefficients in the case of carbon dioxide) have been compared with the available experimental data. A set of elastic and inelastic cross-sections has been collected for each gas such that the computed and experimental values gave good agreement for each swarm parameter over the entire E/N range. In addition the percentage of energy lost by different types of inelastic collisions and also the mean swarm energy have been given as a function of E/N for each gas.

Calculations have been made for the electron swarm parameters in mixtures of argon and metal vapour for E/N varying from 2.82 to 282 Td. Three metal vapours, namely sodium, potassium and caesium, have been investigated for conditions in which the concentrations of metal vapour varied from 0.001% to 20%. The results have shown that for a small percentage of metal vapour both the ionisation coefficient and the drift velocity have higher values than in either pure argon or pure metal vapour. The mean energy and the ratio of radial diffusion coefficient to mobility have both shown monotonic variations at a fixed E/N from the higher values in pure argon to the lower values in pure metal vapour. The radiation emission has also been computed. It is observed that for a range of E/N determined by the percentage of metal vapour, that most of the swarm energy is emitted as metal vapour radiation.
