摘要:

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.
