High-resolution imaging of warm x-ray sources with a Wolter optic on the Z Machine

POSTER

Abstract

We have developed a Wolter optic$^{\mathrm{\thinspace }}$to image warm (\textgreater 15 keV) x-ray sources on the Z Machine, the first-ever instrument of its kind specifically designed and fabricated for HED applications. Adapted from observational astronomy for Z, the optic uses curved x-ray mirrors to form an energy band-limited 2D image of a source with 5-mm FOV and better than measured 100-$\mu $m resolution on-axis. The first images obtained by the instrument of Mo wire array z-pinches on the Z Machine demonstrate unprecedented spatial resolution and signal-to-noise compared to pinhole imaging, revealing small-scale structures not previously observed in these sources.
