High-energy-resolution diced spherical quartz analyzers for resonant inelastic X-ray scattering

Abstract

A novel diced spherical quartz analyzer for use in resonant inelastic X-ray scattering (RIXS) is introduced, achieving an unprecedented energy resolution of 10.53 meV at the Ir L 3 absorption edge (11.215 keV). In this work the fabrication process and the characterization of the analyzer are presented, and an example of a RIXS spectrum of magnetic excitations in a Sr 3 Ir 2 O 7 sample is shown.
