Experimental Methods

  • Resonant Inelastic X-ray Scattering (RIXS): RIXS is a photon-in/photon-out spectroscopy that records the energy and momentum-transfer of light, which can be used to extract the energy-momentum dispersion of elementary excitations of lattice, electronic, spin and orbital nature.  It provides bulk, chemical and site specificity.
  • X-ray Absorption Spectroscopy (XAS): Precise determination of the photon energy and bandwidth that needs to be delivered by the beamline monochromator can be made only on the basis of an accurate XAS measurement from the sample under investigation.  This requirement calls for the use of single photon sensitive point detectors, such as avalanche photodiodes (APD) or microchannel plate detectors (MCP), that must also be shielded from stray optical light.  XAS measurements will be made in total fluorescence yield mode.
  • Resonant Elastic X-ray Scattering (REXS): Bragg and/or superstructure reflections measurements are needed for accurate positioning of the sample in reciprocal space.
