Abstract

We develop a collisional radiative (CR) model of high-Z multiple charge ions based on computational atomic data. We use an algorithm to determine a set of atomic energy levels in the model with significant population in the plasmas and contribute to the dielectronic recombination (DR) processes. The model is validated through participation to the non-LTE kinetics workshops. At the nLTE workshop, an alternative method for the analysis of the spectrum from plasmas based on genetic algorithm (GA) is also discussed. An application of the present model to calculate the ion abundance and radiative power loss of Gd and Nd plasmas is also shown.
