The interaction of strong shock waves, such as those generated by the explosion of supernovae, with dense interstellar clouds is a problem of fundamental importance in the interstellar medium and may lead to the formation of a new generation of stars. In our own galaxy, the structure observed in the Cygnus Loop has been attributed to the development of hydrodynamic instabilities from such shock-cloud interactions. We will present the results of a series of experiments investigating the evolution of a high density sphere after the passage of a strong shock wave, thereby emulating the supernova shock-cloud interaction. The Nova laser is utilized to generate a strong (M ~ 10) shock wave which travels along a miniature, beryllium shock tube, 750 μm in diameter, filled with plastic. Embedded in the plastic is a copper microsphere (100 μm diameter) and its evolution as well as the trajectory of the shock wave are diagnosed via face-on radiography. Two- and three-dimensional simulations of this experiment done with an adaptive mesh refinement (AMR) code and an arbitrary Lagrangian and Eulerian (ALE) code will also be presented.
