PrismSpect and Spect3D with Flexible Atomic Code Data

PrismSpect and Spect3D belong to a suite of codes developed at the Prism Computational Sciences Inc. They employ detailed collisional radiative kinetics models and multi-dimensional radiative transfer to compute emission and absorption spectra of plasmas under a wide variety of physical conditions. Flexible Atomic Code (FAC) is a widely used computational atomic physics software package capable of generating complete data sets of energy levels, radiative transition rates, and collisional cross sections of arbitrary atomic ions. Here we present the integration of FAC atomic data with the Prism Atomic Model Builder Application to generate customized atomic model files, which can then be used in PrismSpect and Spect3D for both LTE and nonLTE spectral modeling. Detailed Comparisons of resulting spectra with those generated from Prism's standard ATBASE atomic data will be discussed, as well as those generated from FAC's built-in collisional radiative model.
