Modeling and Interpretation of Nova's Symmetry Scaling Data Base

Abstract

Our 2D LASNEX simulations of Nova's nine symmetry scaling data bases reproduce the fundamental features seen in the experiments. In particular, we predict how we must change Nova's beam pointing in order to achieve best symmetry with various pulse shapes. This need to change pointing with different pulse shapes is the result of a bulk-plasma-induced migration of the laser deposition/x-ray production region. We have observed and modeled this migration.
