Three-dimensional modeling and hydrodynamic scaling of high density carbon ablator implosions on the National Ignition Facility

ORAL

Abstract

Recent implosion experiments using high density carbon ablators on the National Ignition Facility have achieved neutron yields exceeding 1016. Three-dimensional, high-resolution modeling of these cryogenic implosions shows encouraging agreement with experiment in many respects. This includes x-ray and neutron imaging data from the implosions, flange nuclear activation detector (fNAD) maps, and directional neutron spectral measurements, as well as scalar observables such as total neutron yield. This talk reviews the status of these high-resolution simulations, their comparison to experiment, and where discrepancies still remain. Preliminary results using these simulations to assess hydrodynamic scaling to higher energy will also be discussed.
