Opacity Experiments At The National Ignition Facility (NIF)
ORAL
Abstract
X-ray opacities are essential to the radiation-hydrodynamic simulations used to model astrophysical systems or inertial confinement fusion experiments. Recent opacity experiments have shown up to a factor of two discrepancy between theory and experiment. To address this issue a new experimental opacity platform is being developed on the NIF to crosscheck the recent results. The first experiments, starting in 2017, will begin by measuring the opacity of iron at a temperature of \textasciitilde 160 eV and an electron density of \textasciitilde 7x10$^{\mathrm{21}}$ cm$^{\mathrm{-3}}$. This and several following presentations will describe this effort.
