Journal ArticleDOI
Elliptical x-ray microprobe mirrors by differential deposition
TL;DR: In this article, a differential coating method is described for fabricating high performance x-ray microfocusing mirrors, which can be modified to produce elliptical surfaces with low roughness and low figure errors.
Journal ArticleDOI
Short Focal Length Kirkpatrick-Baez Mirrors for a Hard X-Ray Nanoprobe
Wenjun Liu,Gene E. Ice,Jonathan Z. Tischler,Ali M. Khounsary,Chian Liu,Lahsen Assoufid,Albert T. Macrander +6 more
TL;DR: In this paper, the authors describe progress in the fabrication of short-focal-length total-external-reflection Kirkpatrick-Baez x-ray mirrors with ultralow figure errors.
Journal ArticleDOI
Reconstruction of an astigmatic hard X-ray beam and alignment of K-B mirrors from ptychographic coherent diffraction data

TL;DR: Good agreement between the reconstructed wavefront obtained from theX-ray data and off-line metrology data obtained with visible light demonstrates the usefulness of the technique as a metrology and alignment tool for nanofocusing X-ray optics.
Journal ArticleDOI
Improvements in the accuracy and the repeatability of long trace profiler measurements.
TL;DR: Modifications of the long trace profiler at the Advanced Photon Source at Argonne National Laboratory have significantly improved its accuracy and repeatability for measuring the figure of large flat and long-radius mirrors.
