PEEM/XAS beamline

PEEM/XAS BEAMLINE (Photoemission Electron Microscopy / X-ray Absorption Spectroscopy) - the bending magnet beamline is dedicated to microscopy and spectroscopy in the absorption of soft X-rays. It is co-operated by the Jagiellonian University, Jerzy Haber Institute of Catalysis and Surface Chemistry PAS, and AGH University of Science and Technology in Kraków.

End-stations:

  • PEEM end-station (Photoemission Electron Microscopy) - an electron microscope that uses low energy electrons emitted from a sample after excitation with a photon source to create an image with a spatial (lateral) resolution of
    a few dozen nanometres.
  • XAS end-station - a universal station for X-ray absorption spectroscopy.
