Abstract :
Summary form only given. The temporal evolution of neutral species concentrations of H2O, OH, CO2, CO, NO and N2O were investigated in air plasma produced by a 100 keV electron beam from atmospheric pressure down to ~ 1 mTorr. The investigation involves both experimental methods and the output of an air-chemistry simulation program. Tunable diode laser absorption spectroscopy was used to provide information on the temperatures and absolute values for the concentrations over a broad dynamic range. The spectrometer utilizes a set of fiber-coupled distributed feedback lasers, operating in the near-infrared. Absorption spectra were obtained with the temporal resolution of 1 ms or better.
