Abstract:

This article deals with the investigation of dc plasma discharge of Ar–CO gas mixture in which the relative electron density and absolute temperature were measured. Relative electron density and absolute temperature were obtained for the mixture at discharge powers between 200 and 12 000 mW, and pressures between 0.1 and 0.5 mbar employing the radiative collisional model for several Ar–CO mixtures. Behavior of the electron temperature and relative number density are discussed. The absolute number density of the 1s5 was found to be higher than that of the 1s3 level.
