Study of Radiation of Nonequilibrium Nitrogen Plasma with a Maecker Type Plasma Generator

Abstract

Nonequilibrium radiation of nitrogen plasmas generated by the Maecker type plasma generator was studied mainly by a spectroscopic method. It was found that the plasma generator, if operated under the low-pressure and low-discharge current conditions, could produce high temperature and significantly nonequilibrium nitrogen plasmas. Theoretical and experimental intensity distributions of N₂ and N₂⁺ band systems agreed very well, indicating the validity of the nonequilibrium dissociative rate constants and collisional-radiative process model included in the theory.
