Calculation of plasma transmission spectra using the superconfiguration method with orbital relaxation effects

Journal of Quantitative Spectroscopy and Radiative Transfer, 1997
Abstract We describe a program developed at CEA Limeil-Valenton for the calculation of absorption spectra. This program is based on the idea of the Superconfiguration method proposed by Bar-Shalom et al. and implemented in their Super Transition Arrays code (STA).

Analysis of a non-LTE xenon spectrum by means of the model of superconfiguration temperatures

Journal of Quantitative Spectroscopy and Radiative Transfer, 2003
Abstract The method of superconfiguration (SC) temperatures is used for interpreting the experimental spectrum of a non-LTE xenon plasma with kT e =450 eV and n e =1.2×10 20 cm −3 . 109 SCs are selected for representing the eight relevant ions. The coefficients of the linear equations for the populations and

A superconfiguration model for broadband spectroscopy of non-LTE plasmas

Journal of Physics B: Atomic, Molecular and Optical Physics, 2000
We present an atomic physics package called AVERROES/TRANSPEC for studying plasma spectroscopy of complex L-, M-shell emitters or even core-excited multielectron K-shell emitters. The model, which is also intended to give some insights on ionization properties of M-shell ionized plasmas, is divided into two parts.

Effective superconfiguration temperature and the radiative properties of nonlocal thermodynamical equilibrium hot dense plasma

Physics of Plasmas, 2005
The model of superconfiguration (SC) temperatures has been used extensively for computing the population dynamics of very large systems in hot dense plasmas. Plasmas of Ge, Xe, and Au have been studied for a wide range of values of Te and Ne. For plasmas containing a distribution of a dozen of ionization states, two systems of a few hundreds of linear ...

Chemical‐Picture‐Based Modeling of Thermodynamic Properties of Dense Multicharged‐Ion Plasmas Using the Superconfiguration Approach

Contributions to Plasma Physics, 2009
AbstractUsing the chemical‐picture representation of plasmas as a mixture of various ions and free electrons, a consistent description of thermodynamics of dense multicharged‐ion plasmas is being developed that involves the effects of Coulomb non‐ideality and degeneracy of plasma electrons; contribution of the excited ion states (on the base of the ...

Superconfiguration accounting approach versus average-atom model in local-thermodynamic-equilibrium highly ionized plasmas

Physical Review E, 1999
Statistical methods of describing and simulating complex ionized plasmas requires the development of reliable and computationally tractable models. In that spirit, we propose the screened-hydrogenic average atom, augmented with corrections resulting from fluctuations of the occupation probabilities around the mean-field equilibrium, as an approximation
