CNR at synchrotron radiation sources Alberto Morgante CNR-IOM Trieste CNR runs: 9 beamlines open to international users at international synchrotron radiation sources: Elettra (Trieste, Italy) and ESRF (Grenoble France) In the period 2010-2013: 839 experiments approved by international review committees and carried out at CNR beamlines 549 publications on international Journals 76 in journals with IF > 6 CNR Institutes: IOM ISM IC Experimental techniques: X-ray spectroscopies (absorption, photoemission) to study electronic structure of nanometerials, of thin films, of molecular complexes, dynamics of electron transport processes X-ray absorption and spin-resolved photoemission techniques to study magnetic properties of materials X-ray diffraction for structural analysis (proteins, nanomaterials, thin films) CNR beamlines at Elettra ALOISA APE BACH BEAR CIPO GasPhase Lilit XRD1 VUV Photons: From UV to hard X-rays Beamlines specialised for different fine analysis tecniques. Gilda Italian Beamline at ESRF 25% of italian beamtime at ESRF at Gilda Beamline operational since 1994 No major instrumentation upgrades since 1994 Gilda run by CNR staff (at the moment 2 scientists and 1 post-doc) Chemistry: Proton conductors, catalysts based on metallic nanoparticles, interface reactions between solids, electrochemistry Crystals: local order in magnetic semiconductors, multiferroics Applied materials science: luminescent materials for optics, doping in semiconductors and insulators, materials for magnetic storage, structure of cements.

Cultural Heritage: characterization of pigments and chromophores, deterioration processes Cultural Heritage: The baptism of Jesus, banner by L. Signorelli. From: I. Cianchetta et 26 CNR researchers involved Advanced instrumentations (large investment in the past) Important service to the italian and international scientific community International selection committee competition higher scientific level of research Opportunities of collaborations with top international research groups Beamlines need to be reliable for users need of maintenance funds Beamlines need to be world competitive upgrades
