Opacity calculations for ICF target physics using the ABAKO/RAPCAL code

Abstract

In this work we present a set of atomic models (called ABAKO/RAPCAL), and its validation with experiments and with other NLTE models. We consider that our code permits the diagnosis and the determination of opacity data. A review of calculations and simulations for the validation of this set is presented.As an interesting product of these calculations, we can obtain accurate analytical formulas for Rosseland and Planck mean opacities. These formulas are useful for the use as input data in hydrodinamic simulations of targets where the computation task is so hard that in line computation with sophisticated opacity codes is prohibitive. Analytical opacities for several Z-plasmas are presented in this work.
