2-D OMEGA Capsule Implosions
ORAL
Abstract
We have an upgraded laser energy deposition package in our AMR-Eulerian radiation-hydrodynamic code called RAGE. As part of our validation effort, we ran 2-D simulations for a series of OMEGA direct drive implosion capsules that have shell thickness ranging from 7.2 to 29.3 microns and different gas fills. These simulations include the effect of surface roughness, laser spot non-uniformity, the mounting stalk, and the glue spot. We examined the sensitivity of our simulated results to equation of state choices, ion diffusion, and mix model. Our simulated results compare well to the experimental yield, ion temperature, burn width, and x-ray size data.
