Popis: Experimental investigations of radio-frequency discharges in O 2 /He/NO mixtures in the pressure range of 1-100 Torr and power range of 0.1-2.5 kW have indicated that O 2 (a 1 Δ) production is a strong function of geometry, pressure and diluent ratio. The goal of these investigations was maximization of both the yield and flow rate (power flux) of O 2 (a 1 Δ) in order to produce favorable conditions for application to an electric oxygen-iodine laser (EOIL). As pressure is increased, yield performance is dominated by the influence of geometry and diluent ratio. Numerous measurements of O 2 (a 1 Δ), oxygen atoms, and discharge excited states are made in order to describe the discharge performance dependence on various parameters.
