Fabrication imperfections and their implications for implosion symmetry and yield in double shell simulations

ORAL

Abstract

Double shell implosions are designed to achieve fusion by volumetric ignition. Fabrication imperfections in the manufacturing of a double shell capsule such as component offsets and gaps in the ablator joint can have significant impacts on the outcomes of an experiment. In this talk, I will discuss recent radiation hydrodynamics simulations performed to evaluate the individual and collective impact of measured fabrication features on capsule implosion symmetry and yield. We observe that the ablator gap size can heavily tune inner shell shape and that in certain contexts ablator gaps and component offsets can interact to degrade yield significantly.
