Abstract
Theoretically determined radiative properties for argon and argon/copp er plasmas at one atmosphere, in the temperature range from 3000 to 25 000 K, are presented. The spectrum from 0.03 to 25 mu m is covered. Th e spectral emission coefficient, integrated emission coefficient, and net emission coefficient are the properties considered. To determine t he limits of the optically thin regime, the intensity for a line-of-si ght in an isothermal, homogeneous plasma versus pathlength is compared to the intensity calculated with the optically thin assumption. To ob tain information on the dominating emission mechanisms, the fractional contributions of the bound-bound (line), free-bound, and free-free em ission are shown. To obtain information on the dominating species, plo ts of the fractional contributions of each of the atom and ion types i s presented. Because it is of interest to know how much of the total r adiation is in the vacuum ultraviolet wavelength region, fractional pl ots of this are presented too.
