Study of chromatic aberrations in x-ray crystal imagers for plasma diagnostics

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...
