Abstract
The integration of computational atomic physics and information technology can provide flexible, convenient tools for high energy density physicists both computational and experimental. In this work, a flexible atomic database is applied to plasma opacity and spectrum calculations. Multiple atomic data models, such as screened hydrogenic, non-relativistic (ATBASE) and jj split relativistic (RSSUTA), are seamlessly incorporated into the software architecture. High performance parallel programming is applied to accelerate the computation of both the atomic data and the opacity calculations. The user interface is graphical and provided as an easy to use and convenient method to access the data and diagnose the calculations. We present opacity and spectrum results for Kr and Nb plasmas as examples of this new capability.
