Description

Laboratory opacity experiments have been developed at the Sandia Z facility over the last fifteen years. Model predictions for iron opacity are notably different from measurements performed at conditions similar to the boundary between the solar radiation and convection zone [J.E. Bailey et al., Nature 517, 56 (2015)]. In this presentation we describe the experimental methods, some of the tests performed to assess the reliability and accuracy, and possible directions for future research. ++ Sandia National Laboratories is a multimission laboratory managed and operated by National Technology and Engineering Solutions of Sandia LLC, a wholly owned subsidiary of Honeywell International Inc. for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525.
