Abstract

Transport and implosion experiments have been conducted on the OMEGA 24-beam, uniform-irradiation facility. Thermal transport in spherical irradiation was found to be different than in comparable, single-beam target irradiation and could not be described in terms of a flux-inhibited model. Deep energy deposition in spherical irradiation (by electrons on the tail of the thermal velocity distribution) was found to lead to a temperature profile which is not as steep as predicted by a flux-inhibited model. This apparently leads to more explosive implosion (i.e., higher core temperature) than predicted by using such a model.
