摘要：
Implosion of inertial confinement fusion (ICF) capsule is very sensitive to the growth of sphericity perturbations. The control of the feeding of such perturbations and their transport ("feedthrough") through the ablator is a key point to reach ignition. Since 2002 [1, 2], experiments have been designed and performed on the Omega laser facility in order to study these phenomena in planar geometry. A new "rugby shaped" hohlraum was used [3,4]. We present experimental results and comparisons with numerical simulations.
