Laser-Driven Counter-Propagating Shear Experiments [Slides]
RAGE calculations with BHR can match mix-width data generated in the counter-propagating shear experiment. The data is sensitive to the initial turbulent length scale parameter in BHR, the mix widths to a window of about 15 microns, the dust-up to a window of a few microns. The turbulent length scales which match the experiment are set by the initial width of the layer, rather than the initial roughness of the layer. Orthogonal radiography captures strong nonlinear evolution and transition to increasingly fine, diffuse structures. A NIF experiment with supported shocks could extend to later mixing times, longer shear regions, thicker plates, etc. and explore substantially more parameter space.

Summaries of FY12 LANL Experimental Campaigns at the OMEGA Laser Facility
In FY 2012, Los Alamos National Laboratory (LANL) executed 244 total shots on OMEGA. LANL experiments contributed to the National Ignition (NIC) campaign in the following ways: • Measured the x-ray ablative Richtmyer-Meshkov growth of isolated defects on plastic ablators, • Studied branching ratios in DT fusion plasmas, and • Continued neutron imaging and radchem scintillator development for NIF.
