Application of variably-doped ablators to NIF capsules

ORAL

Abstract

2D LASNEX simulations indicate that polar angle- and depth-dependent doping of inertial fusion capsule ablators can effectively compensate for radiation drive asymmetries [1]. We present simulations of a NIF capsule design [2] with variable in-depth doping to compensate for low order radiation asymmetry modes. Such symmetry compensated capsules could allow modifications to the laser pointing within the NIF hohlraum that increase the radiation asymmetry, but reduce the potential for deleterious laser plasma interactions.
