Abstract A series of experimental measurements of ozone concentration produced by irradiation of noble gas (He, Ne, and Ar)-O2 and noble gas-O2-SF6 mixtures with energetic (MeV) helium and lithium ions are reported. Continuous irradiations at dose rates of 1015–1017 eV cm −3 s −1 for a few hundred milliseconds were used. The resulting ozone concentration was found to be nonlinear with dose rate for a given irradiation time. This nonlinearity was effectively reduced by an increase in noble gas pressure. Few mole percent addition of SF6 generally resulted in an increase in the ozone concentration. This increase was highest for lower noble gas pressures and longer irradiation times. Further SF6 addition, however, caused a reduction in the ozone concentration. Results are explained by considering the relevant reactions responsible for ozone production and loss.
