Abstract
A base-line capsule design for the Laser MegaJoule
facility is optimized by radially grading the Ge dopant in plastic ablator.
A one dimensional robustness study is performed to optimize the implosion
and the entropy deposition. Then, the tolerance versus the ablator roughness
is examined for modes over 10 through direct two-dimensional simulations.
The stability is significantly higher than that of an uniformly doped
design.
