We investigate chromatic aberrations in x-ray crystal imagers. For on-axis point-to-point imaging, second-order astigmatism can be eliminated by the optimal choice of meridional and sagittal radii, but higher-order aberrations generally remain. In crystals and other diffractive reflectors these aberrations are termed c...

X-ray radiography at the National Ignition Facility (NIF) must simultaneously achieve micron-scale spatial resolution and adequate signal-to-noise ratio with a limited number of 7.2-keV photons. To address this coupled resolution-throughput challenge, we developed a scintillator-based x-ray imager using a tandem micros...

Measurements of x-ray absorption/opacity in ionized plasmas at the National Ignition Facility in experiments with high neutron yields require large detector standoff distances, motivating advances in opacity spectrometer design. We propose a spectrometer in which x rays first reflect from a sagittally focusing mirror w...
