15A Advanced Micro-Crystal Chemical crystallography Beamline

With a highly brilliance micro-focus X-ray beam, a high precision kappa-geometry goniometer and a large-area detector, 15A aims to determine 3D crystal structures from micro-scale single crystals and non-ambient conditions.

UNIQUE FEATURES

  • Micro-size chemical crystal structural determination
  • Non-ambient crystal structural characterization:

     - photo-excitation,

     - high pressure (Up to 20 GPa )

     - ultra low temperature (15 K )

  • Pink beam Laue diffraction
  • Sub-nanosecond time-resolved Single crystal diffraction
