Ionization balance of non-LTE plasmas from an average-atom collisional-radiative model

We present a simplified version of an average-atom collisional-radiative model employing both local-thermodynamic-equilibrium and isolated-ion atomic data. The simplifications introduced do not lead to any substantial errors, they significantly speed up calculations compared with the basic involving direct solution self-consistent-field equations. Average ion charges, charge state distributions, emission spectra non-local-thermodynamic-equilibrium (NLTE) gold plasmas calculated using various modifications are those obtained THERMOS detailed configuration accounting approach. also propose efficient method calculate thermodynamic functions NLTE in context model.
