We present data from recent high-energy-density laboratory experiments designed to explore the Rayleigh-Taylor instability under conditions relevant to supernovae. The Omega laser is used to create a blast wave structure that is similar to that of the explosion phase of a core-collapse supernova. An unstable interface is shocked and then decelerated by the planar blast wave, producing Rayleigh-Taylor growth. Recent experiments were performed using dual, side-on, x-ray radiography to observe a 3D "egg crate" mode and an imposed, longer-wavelength, sinusoidal mode as a seed perturbation. This paper explores the method of data analysis and accurately estimating the position of important features in the data. [ABSTRACT FROM AUTHOR] |
