Monte Carlo simulation of ion-ion recombination in methane and sulphur hexafluoride

Abstract: Recombination of ions in mixtures of methane and sulphur hexafluoride has been simulated in Monte Carlo technique. The results of the simulation can be directly compared with experimental measurements. As a function of gas pressure, the recombination rate has a maximum of approximately 10-6 cm3 s-1 at a pressure of 1 atm, in good agreement with experimental results.

“…in the CH 4 :SF 6 :He = (1 − δ)/2:(1 − δ)/2:δ mixtures at 300 K. To obtain the recombination rate in one-component gases at low pressures we used the method of Flannery (1980) for charge transfer scattering between CH + 4 and CH 4 and that of Bates and Mendas (1982) for elastic polarization scattering between SF − 6 (SF 6 ) and SF 6 . For the ion mobilities we took the data by Littlewood and Pyle (1990a) who have performed Monte Carlo simulation to calculate the recombination coefficient under the considered conditions and obtained the result which is in a good agreement with data measured by Littlewood (1990) at moderate pressures (200-600 Torr). Figure 3 shows our results in comparison with the Monte Carlo results by Littlewood and Pyle (1990a).…”

Figure 3 shows our results in comparison with the Monte Carlo results by Littlewood and Pyle (1990a). Our calculation agrees rather well with the Monte Carlo simulation and shows the pronounced synergism in the pressure range of 550 < p < 920 Torr which is explained in the same terms as that for process (21) in the He:Ar mixture.…”
