Calculation of optical characteristics of nonequilibrium plasma

Abstract

A collisional-radiative model has bene developed to calculate the physical and optical characteristics of thermodynamical nonequilibrium plasma. The mean charge of plasma ions, the ionization-state density, radiative energy losses, line ratios, the opacities and the emissivities have been calculated for the steady-state optically transparent plasma, which contains aluminum or copper multi charged ions, in a broad range of plasma densities and temperatures. The comparison shows that our result agree satisfactorily with the calculation results of other authors and with the experimental data.
