Description
The X-Ray Fluorescence beamline, developed by Elettra Sincrotrone Trieste and operated in partnership with the International Atomic Energy Agency (IAEA), has a high-versatity optical design. Depending on the experimental needs, one can choose between an X-ray beam having high flux or high energy resolution in a broad energy range (2-14 keV) [1].
In the experimental hutch, the beamline hosts a multipurpose X-ray spectrometry endstation [2] which is well suited for any vacuum-compatible samples.
The manipulator and the set of detectors installed in the chamber are routinely exploited to perform XRF, X-ray Absorption Near Edge Spectroscopy (XANES) and X-Ray Reflectivity (XRR).
As far as XRF and XANES are concerned, when the standard geometry (45/45) is not adequate to characterise the samples, other options can be adopted, i.e. grazing incidence, grazing exit, total reflection and - our most recent addition - x-ray standing wave excitation.
The characteristics of this beamline are suitable to a wide variety of fields including, but not limited to: fundamental physics, medicine, biology, cultural heritage, environmental science.
