BioXAS Imaging beamline is a multi-resolution X-ray fluorescence (XRF) imaging beamline with capabilities to collect XRF imaging data in macro-, micro- and nano-modes. The former two scanning modes are accepting General Users’ proposals and the latter is currently under commissioning.

Spectral Range

5-21 keV


Imaging & Microscopy

  • Macro XAFS/XRF Imaging
  • Micro XAFS/XRF Imaging
  • Fluorescence Microscopy
Optical Compound Microscopy (non-fluorescence)


Typical samples used at BioXAS-Imaging are plant or animal tissues, or pieces of rock. On-site capabilities for thin-sectioning samples are available and can be arranged by talking to beamline staff.

Samples are mounted onto holders/frames at a designated area at the BioXAS Imaging beamline.
