A superconfiguration model for broadband spectroscopy of non-LTE plasmas

We present an atomic physics package called AVERROES/TRANSPEC for studying plasma spectroscopy of complex L-, M-shell emitters or even core-excited mu ltielectron K-shell emitters. The model, which is also intended to give som e insights on ionization properties of M-shell ionized plasmas, is divided into two parts. The first part (AVERROES) is based on the superconfiguratio n concept and on the supertransition array method. It generates superconfig uration average-energies, collisional and radiative rates needed for a calc ulation of population kinetics. It also calculates the statistical shift an d width associated with each possible radiative electron jump between selec ted superconfigurations. All the previously mentioned quantities are stored on files readable by a multicell time-dependent collisional-radiative mode l (TRANSPEC) that calculates population kinetics and synthetic emission spe ctra. This last code can be employed with a hydrodynamics code to provide s imulated x-ray ouputs of non-steady-state inhomogeneous plasmas.
