W/SiC x-ray multilayers optimized for use above 100 keV.

We have developed a new depth-graded multilayer system comprising W and SiC layers, suitable for use as hard x-ray reflective coatings operating in the energy range 100-200 keV. Grazing-incidence x-ray reflectance at E = 8 keV was used to characterize the interface widths, as well as the temporal and thermal stability in both periodic and depth-graded W/SiC structures, whereas synchrotron radia...

keV SOFT X-RAY BACKGROUND

Snowden and coworkers have presented a model for the 1 4 keV soft X-ray diffuse background in which the observed flux is dominated by a ∼ 10 K thermal plasma located in a 100–300 pc diameter bubble surrounding the Sun, but has significant contributions from a very patchy Galactic halo. Halo emission provides about 11% of the total observed flux and is responsible for half of the H I anticorrela...

X-ray phase-contrast imaging at 100 keV on a conventional source

X-ray grating interferometry is a promising imaging technique sensitive to attenuation, refraction and scattering of the radiation. Applications of this technique in the energy range between 80 and 150 keV pose severe technical challenges, and are still mostly unexplored. Phase-contrast X-ray imaging at such high energies is of relevant scientific and industrial interest, in particular for the ...

Design of X-UV multilayers for high X-ray flux

2014 Many promising applications for multilayer X-ray optical elements 2014 X-ray laser cavities, plasma diagnostics, synchrotron optics, etc. 2014 subject them to intense X radiation. This paper discusses the initial attempts at understanding the physical processes that are likely to degrade the performance of multilayer X-ray mirrors, the selection of optimal pairs of materials to resist heat...

Introducing an Optimized Method for Obtaining X-ray Diffraction Patterns of Biological Tissues

Introduction Individual X-Ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. Many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the X-Ray diffraction patterns resulting from coherent scattering. The goal of this study was to introduce an optimized method for obt...
