Using planar analogue experiments to aid design of double shell capsules
POSTER
Abstract
Qualitative observations provide guidance for double shell capsule design choices. Consideration of material density and opacity properties led to a series of planar analog experiments using the Omega laser facility. These experiments showed aluminum to be the best material for the ablator (outer shell). The joint between the two outer shell hemispheres, required for fabrication, can introduce large distortions of the capsule symmetry during implosion. Of the three different joint shapes tested, the grooved joint showed less distortion. Shock timing measurements showed that an Eulerian radiation-hydrodynamics simulation code was adequate to use for detailed design.
