Paper Abstract

In the frame of a CEA/US DOE collaboration, radiation driven spherically convergent experiments were performed on the Nova laser in order to measure the Rayleigh-Taylor growth at the ablation front. Numerical simulations using het 2D Lagrangian code PCI2 have correctly reproduced experiments in moderate convergent geometry. Experiments have addressed convergence ratios up to 4 by considering larger capsules, larger hohlraum and longer laser pulses. Numerical analysis of these high convergence implosions is presented, and the effect of convergence on the Rayleigh-Taylor growth is investigated.
