Ion-ion recombination in mixtures of methane and sulphur hexafluoride

Abstract: We have measured the recombination rate for positive and negative ions in sulphur hexafluoride and in mixtures of methane and sulphur hexafluoride in an electron beam sustained discharge. Measurements were made as a function of gas composition, gas pressure in the range 100 to 600Torr, and reduced electric field strength in the range 12 to 150Td. When plotted as a function of an effective ion temperature, defined by the drift velocities of the ions in the applied electric field, the rates in each of the gas mi… Show more

“…inter-ionic interaction potential has a saddle point which decreases the probability that one ion captures another after a collision between the latter ion and an atom; this is controlled by the absolute value of E. The rate of process (28) has been measured as a function of E in CH 4 :SF 6 (Cornell and Littlewood 1987) and CH 4 :SF 6 :Ar and CH 4 :SF 6 :He (Littlewood 1990) mixtures. A Monte Carlo simulation by Littlewood and Pyle (1990b) has given the results which agree well with the available experimental data on the rate of process (28) in the CH 4 :SF 6 mixture versus E.…”

“…In the limit E → 0 Thomson's approach gives γ = 3 for the polarization ion-atom interaction (see, for instance, Bates 1985). Using another definition of the effective ion temperature Cornell and Littlewood (1987) and Littlewood (1990) have analysed the recombination rate measured in the CH 4 :SF 6 , CH 4 :SF 6 :He and CH 4 :SF 6 :Ar mixtures as a function of electric field and obtained γ = 1.6.…”
