Abstract

Summary form only given. Experiments on the Pegasus II pulsed power facility at Los Alamos are being conducted to study the evolution and flow of strengthless materials as a result of being shocked. Of particular interest is vorticity and mixing that is induced in the materials by a shock-wave passing through a non-uniform boundary. The experiments provide an important benchmark for hydrodynamic codes, and are a precursor to experiments planned on Atlas in which the materials will be pre-ionized before being shocked.
