Paper Abstract

Investigations on a pulsed O2 plasma under low pressure (1 - 10) mbar have been carried out. Microwave pulses (2.45 GHz) with a duration of (50 - 200) microsecond(s) and a repetition rate of (10 - 500) Hz are typical for the experiments. The electron density has been determined by means of an HCN laser interferometer. Detection of negative ions O- has been performed using a photodetachment technique with a Nd:YAG laser. A kinetic model predicting the temporal behavior of the densities of oxygen atoms and molecules, metastable singlets O2(a1(Delta) , b1(Sigma) ), negative ions O-, positive ions O+2, ozone, and the electron density has been developed. The experimental and theoretical data are fond to agree well.
