XMCD (under construction)

The planned XMCD beamline will be a specialized research installation using variable polarization radiation, the source of which will be the EPU undulator (elliptically polarizing undulator).

The concept of the beamline assumes the coexistence of two measurement branches, in which the research end-stations will be the PEEM microscope (photoemission electron microscope) and STXM (scanning transmission X-ray microscope). The PEEM branch will also contain an octupol station.

The octupole research station will be dedicated to measurements of magnetic circular dichroism in the absorption of X-rays.

The PEEM end-station with standard equipment will allow for the creation and modification of research systems and imaging of their surfaces in a wide range of temperatures and with high resolution. The main advantage of the method is the ability to select the energy of excitations and the possibility of tuning to the characteristic edge of the absorption.

The STXM end-station will provide chemical analysis at the nanoscale through the combination of X-ray absorption spectrometry and microscopy.

Potential application of the XMCD beamline:

  • Magnetic order research
  • Domain structure research
  • Imaging of the chemical composition
  • Biomolecular spectroscopy
  • Fluorescence detection.
