Synchrotron light (SL) sources are circular accelerators where electrons are accelerated to very high speeds and forced to travel inside special components as bending magnets and insertion devices, causing the emission of electromagnetic radiation. Properties of the light obtained from a synchrotron make it a unique tool in many fields of application, being its main features the high intensity, brilliance, stability and polarization of the beam. Many techniques can be applied with synchrotron light and can classified depending on their base principle; it is worth citing, among others, diffraction, scattering, absorption, imaging, photoelectron emission, reflection and emission techniques. Fields of application include medical and life sciences, environment, material science, cultural heritage and archaeology, among others.
The Physics Section of the IAEA jointly with Elettra Sincrotrone Trieste (EST) in Italy operates a multipurpose X-ray spectrometry end-station at the X-ray Fluorescence beamline of EST. The collaboration developed thanks to a Partnership Agreement signed in 2014 between the two Institutes. The facility is available to external users since the beginning of 2015 through the peer-review process of EST. Using this collaboration framework, the IAEA supports and promotes synchrotron radiation-based research and training activities for various research groups from the IAEA MSs, especially those who have limited previous experience and resources to access a synchrotron radiation facility.
