Spektroskopische Diagnostik eines nichtthermischen He-Plasmas in der Hochstromfackel / Spectroscopical Diagnostics of a non-thermal He-Plasma Jet

Abstract

The properties of a low-pressure non-thermal He-plasma jet have been investigated. The gas temperature was obtained from the population densities of high excited He-levels. The electron density was determined both from the Stark-effect broadening of some He-lines and from the intensities of some forbidden transitions. The radial distribution of electron temperature was found by comparing the computed population densities of the He 31P level with the experimental values.
