Summary form only given. The Sandia Z dynamic hohlraum radiation drive produces high radiation powers and energies. Using these high powers and energies, a new in-situ diagnostic has been developed and tested, that uses the super-sonic to sub-sonic transition of a Marshak radiation wave in a cylindrical block of SiO2 aerogel foam. When this transition takes place, a shock is launched, with a velocity...
Summary form only given. We have measured the production of 10 keV X-rays from low-density Ge-doped aerogel targets at the OMEGA laser. The targets were 1.2 mm long by 1.5 mm diameter beryllium cylinders filled with Ge-doped (20 atomic percent) SiO2 foam. The doped-foam density was 5 or 7 mg/cc. These targets are a major advance over previous doped aerogels: instead of suspending the dopant in the...
