Scientific paper

We describe our progress in developing a new type of "source" for studying compressible hydrodynamic instabilities in systems driven by an admixture of material pressure and x-rays. To generate this, we used half of a scale 1.0 Nova hohlraum; i.e. An Au cylinder 1.6mm diameter, 1.2mm long, heated from only one end with five Nova beams through a 0.8mm diameter laser entrance hole. The other, unilluminated end of the hohlraum is filled with ~300microns of density 0.15g/cc CH foam and has no endcap. An experimental package is mounted on the unilluminated end, in contact with the foam. A 1ns laser pulse of ~11TW creates a temperature of ~170eV inside the half hohlraum. The x-radiation penetrates the foam supersonically at ~M=3. Thus a heated and, therefore, pressurized foam is in contact with the package which also experiences some amount of x-radiation drive. These proof-of-principle experiments indicate the source's performance is close to what we expect from simulation. *Work performed under the auspices of the U.S. Department of Energy by the Lawrence Livermore National Laboratory under Contract W-7405-ENG-48.
