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.Abstract:
We present a sapphire ðAl2O3Þ analyzer for high-resolution X-ray spectroscopy with 31-meV energy resolution. The analyzer is designed for resonant inelastic X-ray scattering (RIXS) measurements at the CuKa absorption edge near 8990 eV. The performance of the analyzer is demonstrated by measuring phonon excitations in beryllium because of its known dynamical structure and high counting rates.read more

Inelastic X-ray Scattering Studies of Electronic Excitations
TL;DR: Inelastic x-ray scattering (IXS) has developed into one of the most powerful momentum-resolved spectroscopies for strongly correlated electron systems, where the interplay of charge, spin, and orbital degrees of freedom determines their physical properties as discussed by the authors.

X-Ray Optics: High-Energy-Resolution Applications
TL;DR: In this article, a theory of X-Ray Fabry-Perot Resonators was proposed. But the theory was not applied in the field of backscattering, and it is not known how to backscatter X-ray data.
