Abstract

Experimental and theoretical studies of singlet oxygen excitation in traveling microwave discharge (TMW) are presented. Singlet oxygen O₂(a¹Δ_g) concentrations and atomic oxygen mole fraction have been measured for different pressures, input powers and distances from mw resonator. It was shown that a steady-state traveling microwave discharge with a coaxial cavity resonator could provide maximal O₂(a¹Δ_g) yield of 22% for 2 Torr of pure oxygen and 27-30% for He : O₂ = 1:1 mixture. Developed two-dimensional (r,z) model for calculations of plasma-chemical kinetics, heat and mass transfer was used for simulation of processes in TMW discharge under study. Effects of gas pressure, gas flow rate and input power are studied and compared with experimental measurements of O₂(a¹Δ_g) concentrations and atomic oxygen mole fractions.
