      Beamline Description
      In Situ X-ray diffraction (IXD) is a diffraction beamline optimized in the medium x-ray energy range ( 6 – 25 keV ), with emphasis on in situ powder diffraction measurements, in the sub-minute time scale , to study structural, morphological and chemical transformations under various conditions.

      Technique(s)
      X-ray Diffraction, Powder
      X-ray Diffraction, Single Crystal
      X-ray Diffraction, Time Resolved
      X-ray Reflectivity

      Research Types
      Structural characterization of advanced energy materials. In situ XRD studies on the chemical reactions, phase transitions and morphological evolution under various conditions.
