Experimental Methods for Studying the Rayleigh-Taylor Instability of Ablatively Accelerated Targets.

Abstract

The authors describe new diagnostic methods for the study of hydrodynamic instabilities in ablatively accelerated targets. These methods include face-on x-ray backlighting that does not require a backlighting laser beam (for growth rate measurement), and a tracer dot technique (for tracking ablation plasma flow). The targets in the experiments are periodically perturbed to provide initial conditions for the growth of the Rayleigh-Taylor instability. (Author)
