IUVS Beamline

Welcome to the Inelastic UltraViolet Scattering Beamline @ Elettra

The IUVS beamline is dedicated to the study of inelastic scattering with ultraviolet radiation, in a time-space domain not accessible at present by other facilities. In the inelastic scattering process, an incident photon, with energy E_i and momentum K_i interacts with the matter. In this interaction the photons can be diffused, with energy E_s and momentum K_s. Here q=K_s-K_i is called "exchanged moment" and is of considerable importance in the study of inelastic diffusion. We can define the “elastic scattering” when the incident photon energy is the same of the diffused one while we refer to “inelastic scattering” when there is an energy variation. It is important to point out that q is directly dependent on the time and energy as well as from the speed of light in the sample (and therefore on its refractive index).

Effect of Ti Speciation on Catalytic Performance of TS-1 in the Hydrogen Peroxide to Propylene Oxide Reaction

Catalytic activity in epoxidation of propylene over TS-1 has been studied as a function of the Ti speciation in some representative samples. Upon spectroscopy-based qualification and quantification of the various Ti species, catalytic activity can be ascribed to the only perfect tetrahedral Ti.

Proposal Submission

We invite users and collabrators to discuss thier proposals with the beamline local contacts well in advance before the submission deadline. This is crucial for a careful assesment of the experiment feasibility and may lead to improvements in the proposed experimental plan. In a restricted number of cases, when doubts arise about the suitability of your samples (sample absorption etc), it may be possible for you to arrange a test. Our website provides a wealth of informaiton on experiment feasibilty and proposal submission. For more info, please vist the IUVS Users section.

Call for proposals

The deadline for proposal submission for beamtime allocation from July 1st to December 31st, 2020 has been postponed from March 16th to April 6th, 2020.
