Measurements of the effects of mix on neutron yield and compression in layered capsule implosions on NIF

ORAL

Abstract

Recent layered capsule implosion experiments on the National Ignition Facility (NIF) included implosions driven with lower-power, longer pulse shapes. While some of these implosions produced higher compression, others produced higher fuel-ablator mix that can be inferred from the stagnation hotspot x-ray emission, neutron yield, and ion temperature. The connection between simulated perturbation growth and measured layered capsule performance, with focus on experimental observations, will be discussed.
