Paper Abstract
Pressure dependence of threshold fluences for dielectric breakdown of pure CF3H and CF3H/CF3T mixtures has been studied using 10.6 micrometers pulses from a TEA CO2 laser. Breakdown thresholds are well above the working fluences required for laser isotope separation of trifluoromethane, allowing the use of tight focused geometries without producing nonselective processes. Analysis of the experimental results suggests that breakdown occurs as a result of a cascade process, and that recombination losses are more important than electron diffusion. In the pressure range studied, the threshold in presence of CF3T was lower than the corresponding value in pure CF3H, as a consequence of the preionization induced by the (beta) decay.
