Determination of the Nitrogen Atom Wall Recombination Probability in Late Afterglow
Original language description
The reaction kinetics in nitrogen flowing afterglow was studied by optical emission spectroscopy. The DC flowing post-discharge in pure nitrogen was created in a quartz tube at the total gas pressure of 1000 Pa and discharge power of 130 W. The optical emission spectra were measured along the flow tube. Three nitrogen spectral systems - the first positive, the second positive, and the first negative were identified. It was found that N atoms are the most important particles in this late nitrogen afterglow, their volume recombination starts a chain of reactions which produce exited states of molecular nitrogen. In order to explain the decrease of N atom concentration, it was also necessary to include the surface recombination of N atoms to the model. The surface recombination was considered as a first order reaction and wall recombination probability ? = (2.16 ? 0.07) x 10-6 was determined from the experimental data.
