Imaging characteristics of an axisymmetric, grazing incidence x‐ray microscope designed for laser fusion research

We report herein the first demonstration of the x‐ray imaging characteristics of an axisymmetric x‐ray microscope designed for laser fusion diagnostics. The design, fabrication, and evaluation of a grazing incidence hyperboloid/ellipsoid x‐ray mirror pair are discussed. Initial data relating the measured mirror surface profiles, the estimated surface roughness, and mechanical alignment of the x‐ray mirror pair to the observed spatial resolution are presented. A revised fabrication approach, utilizing a single point diamond turning feedback technique and resulting in improved resolution, is also discussed.
