ABSTRACT
Indirectly driven, ablative Rayleigh-Taylor instability growth measurements in Ge-doped plastic foils were studied using face-on and side-on x-ray radiography. Laminated samples consisting of alternating layers of Ge-doped and undoped plastic and homogeneous Ge-doped foils were considered. We show for the first time that hydrodynamics do not depend upon structuration of the samples and that stabilization occurs in the case of laminated samples. All data were found to be in good agreement with bi-dimensional hydrosimulations based on theoretical and numerical predictions published earlier [L. Masse, Phys. Rev. Lett. 98, 245001 (2007)], encouraging new designs using laminated structures for ignition capsules.
