Opacity-on-NIF Sample Design

Models of proposed new targets and configurations used in National Ignition Facility (NIF) experiments to measure the x-ray opacity of elements are demonstrated and discussed. Different methods of arranging the components of the targets are explored for increasing the density and temperatures in the targets while keeping the targets uniform and in local thermal equilibrium and maintaining an optimal transmission. This work will describe the outcomes of these computational experiments using Cassio, an Eulerian radiation-hydrodynamics code.
