Production of NO, NO2 and N2O in Air by Breakdown with High Power Microwaves:A Preliminary Report

Abstract

Production of trace nitrogen oxide species in air discharge plasmas was observed with a quadrupole mass spectrometer attached to a specially- designed, S-band waveguide. At pressures between 25 and 200 Torr in the waveguide, nitric oxide (NO) was the most concentrated trace species observed, reaching concentrations of greater than 2% at 200 Torr. Nitrogen dioxide (NO2) was also observed, but only after the discharge had been turned off. NO2 concentrations were slightly lower than NO. At pressures between 9 and 0.3 Torr, the only species observed was nitrous oxide (N2O), which reached a concentration of approximately 2% at the lower pressure. The experimental apparatus, data collection procedures, calibration procedures, data reduction, and results are described in detail. (JES)
