TL;DR: A compilation of suitable crystal materials and viable reflections for hard X-rays, together with energy resolution and throughput information, is presented.

TL;DR: The Medium Energy Resolution Inelastic X-ray Scattering (MERIX) as mentioned in this paper is an instrument for resonanceant inelastic x-ray scattering (RIXS) studies, in which the energy analysis of inelastically scattered photons is performed with segmented spherical crystal analyzers in close to Bragg backscattering geometry.

TL;DR: A nested Kirkpatrick–Baez mirror pair has been designed, fabricated and tested for achromatic nanofocusing synchrotron hard X-rays and achieved a FWHM focal spot of about 150 nm in both horizontal and vertical directions.

TL;DR: The fabrication techniques that were used to make the MLL's are reported, which can produce a linear zone plate structure with a very large ratio of zone depth to width, orders of magnitude larger than can be attained with photolithography.

TL;DR: In this paper, a sapphire analyzer for high-resolution X-ray spectroscopy with 31-meV energy resolution was presented, which was designed for resonant inelastic X-rays scattering (RIXS) measurements at the CuKa absorption edge near 8990 eV.
