Samenvatting

In an effort to obtain a better understanding of the neutral-neutral reactions responsible for the formation of the short lived afterglow (SLA), several diagnostic techniques have been implemented in the same flow tube to probe the axial dependence of the density of neutral species N and N/sub 2/ but also of the electrons resulting from ionisation processes in the afterglow. The absolute ground state nitrogen atom N density is determined by means of an original calibration method based on two-photon absorption laser induced fluorescence spectroscopy. The intra-cavity laser absorption spectroscopy was shown as a powerful approach to directly determine the N/sub 2/ absolute density and also the gas temperature, with a very high sensitivity. Additionally, a first determination of the absolute electron density by microwave interferometry was completed. Supported by the set of data obtained under the same experimental conditions, a simple kinetic model is proposed and discussed to account for the observed behaviors of the different species density
