Experimental methods for studying the Rayleigh-Taylor instability of ablatively accelerated targets

Technical Report ·
OSTI ID:5955708
; ; ; ; ; ; ;
We 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 our experiments are periodically perturbed to provide initial conditions for the growth of the Rayleigh-Taylor instability.
