The CRP aims at expanding and strengthening the research capacity of Member States (MS) in multidisciplinary applications of synchrotron radiation based X-Ray Spectrometry (XRS) techniques. The Physics Section of the IAEA has recently developed and installed an experimental XRS facility as end-station at the X-Ray Fluorescence (XRF) beamline of Elettra Sincrotrone Trieste (EST), Trieste, Italy. Under a cooperation agreement between the IAEA and EST, 40% of the beam time has been granted to the IAEA, accessible to end-users by the second semester of 2014. The IAEA multipurpose beamline end-station allows the synergistic application of various variants of X-Ray Fluorescence (XRF) techniques such as, Grazing Incidence/Exit and Total Reflection XRF in combination with X-Ray Reflectometry (XRR) and X-Ray Absorption Spectrometry (XAS). Targeted applications refer to the characterization of modern nano-structured materials with relevance to energy storage and conversion technologies, micro- and nano-electronics, the investigation of environmental and biological samples, as well as non-destructive characterization of cultural heritage materials. The CRP will connect large MS laboratories hosting synchrotron facilities with small but leading research groups in developing countries, whereas the CRP participants are expected to perform individual or collaborative experiments at the IAEA end-station at Elettra Sincrotrone Trieste.
