Three-Dimensional Hydrodynamic Simulations of OMEGA Implosions

The effect of large-scale (with Legendre modes less than about 10) asymmetries in cryogenic and room-temperature OMEGA implosions were investigated using the 3-D Eulerian hydrodynamic code ASTER. Sources of these asymmetries include laser illumination nonuniformities (because of overlapping the 60 OMEGA beams and power imbalance, mispointing, and mistiming of these beams), target offset, and variation in target-layer thickness.

ASTER simulation of cryogenic shot 7706 are shown here.
