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, total and partial FLY)
-
X-ray excited optical luminescence spectroscopy (XEOL)
VLS-PGM supports material samples stable in ultra high vacuum in a variety of forms, including thin films, pressed pellets, metal chunks, and powders. Some sample temperature controls are available.
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.
