Facilitating research in materials of both fundamental and applied nature, the VLSPGM beamline provides high resolution, low energy spectroscopic studies.


Equipped with a solid state absorption chamber Users can perform experiments requiring techniques such as

  • X-ray absorption spectroscopy (TEY and FLY) 

  • X-ray excited optical luminescence spectroscopy (XEOL) 


We invite Users and Collaborators to discuss their proposal with the Beamline Staff  before the submission deadline.  This is crucial for a careful assessment of the experiment feasibility.
