Over the last decade, the accessibility and technological advancements at large-scale facilities for experimentation have played a vital role in the dramatic increase in the diversity of high pressure (HP) research. Specifically, the range of techniques now available at third generation synchrotron radiation light sources for HP studies is extremely broad, as a consequence of technical advancements in X-ray optics and detectors. The range of in situ techniques for the laser heated-DAC (LH-DAC) that is now available to researchers includes:

  • X-ray diffraction (XRD)
  • Inelastic X-ray spectroscopy (IXS)
  • Extended X-ray absorption fine-structure (EXAFS)
  • X-ray fluorescence (XRF)
  • Mössbauer spectroscopy (SMS)
  • Nuclear forward and inelastic scattering (NFS and NIS)
These synchrotron techniques make possible to probe in situ a significantly diverse number of systems in the LH-DAC, allowing to explore the phase diagrams, chemical reactivity and properties of the elements and compounds to beyond P–T conditions naturally experienced here on Earth.

Synchrotron sources we are currently working with:

Diamond Light Source (DLS), European Synchrotron Radiation Facility (ESRF), Advanced Photon Source (APS)
