Short-pulse laser heating offers the opportunity of creating plasmas of very high energy density in the laboratory. Measurements of the radiative properties of such plasmas are now starting to be performed. Some attempt has been made to reduce the spatial gradients of temperature and density by using buried layer targets. We show in this paper that through extensive computational design work, it is possible to make further reductions in such gradients, thereby significantly increasing the value of such experiments in checking theoretical models of the radiative opacity. |
