Density of oxygen atoms in high pressure (10–50 torr) flowing microwave post-discharges for elastomer treatments

Abstract

Results are presented on the production of oxygen atoms in flowing microwave post-discharges in a reactor of 5 litres at high pressures (10-50 torr). Diagnostics of O-atom densities are obtained by NO titration in the post-discharge. An hydrodynamic and kinetic model has been developed to obtain the spatial distribution of O-atoms inside the post-discharge reactor. Such post-discharge processes at high pressures are of interest for elastomer treatments.
