Gated X-ray images of laser-driven implosions can provide movies of typical
ly 16 frames with similar to 80 ps time resolution and 10 mu m spatial reso
lution, Cylindrical implosions allow study of convergent hydrodynamics but
with excellent diagnostic access down the axis of the cylinder, This exampl
e from a recent cylindrical implosion campaign on the OMEGA laser provides
quantitative data on the growth of ablative Rayleigh-Taylor instabilities i
n convergent geometry.
