ID20 - Inelastic Scattering I

Synopsis

ID20 is dedicated to the study of electronic and magnetic excitations in matter using resonant and non-resonant inelastic X-ray scattering as well as emission spectroscopy. The main scientific activities comprise the investigation of strongly correlated electron systems, functional materials, and the study of matter at extreme conditions.

Technical details

The beamline features two spectrometers: (1) One 1m/2m RIXS spectrometer equipped with five spherical crystal analysers, operating in the horizontal or vertical scattering plane. The overall energy resolution depends on the chosen monochromatisation scheme and the crystal analyser reflection, and ranges from 25 meV to 2 eV. (2) One 1m spectrometer for non-resonant IXS studies with 72 crystal analysers, arranged in six independent modules, and covering both horizontal and vertical scattering planes. The overall energy resolution ranges from 0.4 to 2 eV.

Experimental observables are the following: magnons, d-d and charge transfer excitations, plasmons, core- and valence emission lines, mono-, dipolar- and multipolar transitions from core levels.

IMPORTANT: There is no gas rig system available at ID20. All user equipment must comply with ESRF safety rules and fit ID20 sample stages. Please contact ID20 staff members in case of questions.
