Paper Abstract
X-ray penumbral imaging has been successfully fielded on a variety of inertial confinement fusion (ICF) capsule
implosion experiments on the National Ignition Facility (NIF). We have demonstrated sub-5 μm resolution imaging of
stagnated plasma cores (hot spots) at x-ray energies from 6 to 30 keV. These measurements are crucial for improving
our understanding of the hot deuterium-tritium fuel assembly, which can be affected by various mechanisms, including
complex 3-D perturbations caused by the support tent, fill tube or capsule surface roughness. Here we present the
progress on several approaches to improve x-ray penumbral imaging experiments on the NIF. We will discuss
experimental setups that include penumbral imaging from multiple lines-of-sight, target mounted penumbral apertures
and variably filtered penumbral images. Such setups will improve the signal-to-noise ratio and the spatial imaging
resolution, with the goal of enabling spatially resolved measurements of the hot spot electron temperature and material
mix in ICF implosions.
