SPECTROSCOPIC INVESTIGATION OF ELECTRON TEMPERATURE DISTRIBUTION IN A NONEQUILIBRIUM PARTIALLY IONIZED FLOWING PLASMA.

Abstract

Spatially resolved electron-temperature measurements have been obtained by spectroscopic methods for the case of a nonequilibrium gaseous discharge caused by the passage of direct current between two plane-parallel electrodes in a flowing, partially ionized plasma. These measurements have been made in an arc-heated argon plasma seeded with vaporized NaK, for plasma temperatures ranging from 1300 degrees K to 2100 degrees K and electron number densities ranging from 10 to the 11th power to 10 to the 13th power/cc. It was found that all of the observed measurements fit into a total of eight discharge classifications which describe the prebreakdown and postbreakdown gaseous-discharge characteristics.
