Abstract Text:
Modeling plasmas generally relies on the input of kinetic data for atoms, molecules, and sometimes clusters and dust, e.g., collision cross sections and opacities. The Los Alamos suite of atomic and molecular physics codes [1-3] is a robust suite of codes for calculating atomic and molecular data. The suite allows for LTE plasma opacity calculations of atoms and ions, molecules, dust, as well as a self-consistent equation of state (using the modeled species partition functions) across a wide range of temperatures and densities. For NLTE plasmas, this suite of codes can self-consistently calculate the atomic collisional-radiative data and perform collisional-radiative modeling, while the molecular suite (currently under construction) can calculate the strong collisional data.
In this poster we showcase some representative examples of this suite of codes capabilities for LTE and NLTE plasma modeling, and provide an overview of the physics and workflow required to calculate atomic, molecular and dust opacities, and details of the underlying codes.
