Abstract

The accuracy of opacity models, for warm-dense plasmas, is discussed by a comparison to nine transmission experiments in Al, Fe, FeNaF, Mo, Ho, and Au. The transmission measurements were performed in the NOVA, ASTERIX IV, and Shenguang-II laser facilities during the last three decades, where the achieved temperatures and densities were in the regime of 20–85 eV and 6–30 mg/cc, and the measured energy regimes were relevant to estimate the Rosseland and Planck opacities. A detailed error analysis of the measurements and accuracy analysis of the CRSTA and other models are presented.
