X-Ray Fluorescence

Do you want to have a virtual tour? Have a look at our official video!

Welcome to the X-Ray Fluorescence beamline!

X-Ray Fluorescence is a highly versatile beamline developed by Elettra Sincrotrone Trieste and operated in partnership with the International Atomic Energy Agency (IAEA).

The high-intensity, tuneable X-ray beam, coupled with the high resolving power of the crystal monochromators and with the motorized stages for sample and detectors movement offers the synergistic application of X-Ray Spectrometry, Spectroscopy and Reflectometry techniques.


XRF Highlights / Publications

Shining X-rays on... shimmering gold?

One week of extraordinary brilliance at the XRF beamline: our UHV chamber was lighten up not only by X-rays, but also by the glittering gold of ancient coins. The XRF team, involved in a project by the University of Trieste, has studied a set of gold coins dating back to the III - IV century.

Thanks to the high sensitivity offered by the X-ray beam, the gold purity could be evaluated with high precision, providing fine details to describe the economic inflation during the Roman Empire.

Not only gold, but also trace elements were inspected: elements like Hg and Pb shed light on the processes that Romans used to obtain coins of extraordinary purity; while Pd and Pt are valuable elements to determine the mine location. Besides the precious metals, some attention was paid also to the incrustations found on the coins surface: thanks to 
the analysis of the elements found in such areas, the fate of the coins across the centuries will be unravelled.

Users Area


Call for proposals: next deadline to be announced


Proposal Submission

Collaborators and users are invited to contact the beamtime scientists well in advance the proposal submission deadline to discuss their proposals. This is of great importance to ensure the over whole feasibility of their experiments and a clear assessment of the technical requirements. In some cases, some test experiments can be organized. For more information, please visit the XRF beamline users' corner or the User Area.

Experimental chambers can be temporarily accommodated at the beamline to make use of the monochromatic beam (3.7-14 keV). For more information, please contact the beamline scientists.

Note that proposals can be submitted either via the Elettra Virtual User Office, or via the Way for Light portal.

X-ray Standing Waves

June 2022 - The XRF beamlines has undergone a major upgrade: now EXAFS scans can be carried out at constant q, exploiting X-ray Standing Waves and providing the additional  advantage of depth sensitivity to the elemental selectivity of XAS!

Welcome to Gangadhar Das!

17.02.2021 - Our staff has just welcome a new PostDoc: Gangadhar Das has joined our team and will work on XRF and XAFS beamlines.
