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

摘要

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_3Ir_2O_7 sample is shown.
