The third-generation electron storage ring Elettra, operated by the Elettra Laboratory of Sincrotrone Trieste S.C.p.A. since 1993, feeds 27 beamlines. Researchers from more than 50 different countries, selected by an international committee on the basis of the quality of their scientific proposals, access the facility each year. Since 2010 the Elettra electron storage ring, upgraded with a full-energy injector in 2007, operates in top-up mode for users. Elettra operates routinely at two different electron energies, 2.0 GeV and 2.4 GeV providing photons with energies from a few tenths eV to tenths keV. All of the most important photon (X-ray and IR) based techniques in the areas of spectroscopy, diffraction, scattering, imaging and lithography are present, including also the unique inelastic ultraviolet scattering (IUVS). Versatile experimental stations are maintained at the state-of-the art, offering unique means to carry out outstanding research in diverse fields and disciplines.

ON-LINE SUBMISSION using the Virtual Users Office at the following URL: https://vuo.elettra.trieste.it/pls/vuo/iuu.startup
In compliance with the Elettra - Sincrotrone Trieste policy, if you have already performed measurements at Elettra you must insert the EXPERIMENTAL REPORT in the appropriate field. Failing to do so will prevent you from submitting further proposals.
IMPORTANT: the Elettra Proposal Review Panel gives great relevance to the USERS PUBLICATIONS during the evaluation process.
Make sure your publications in the VUO are duly updated! For more information please check the pages: https://vuo.elettra.trieste.it/pls/vuo/publi_mgr.startup and https://www.elettra.eu/userarea/authorship-and-acknoledgements-policy.html
