In mid-January, a particle beam circulated for the first time in the SESAME (Synchrotron-light for Experimental Science and Application in the Middle East) synchrotron, in Amman, Jordan: an important step towards the start of scientific research activities of the first synchrotron light source in the Middle East. The mission of SESAME, a project based on the CERN model, is to give the Middle Eastern region a world-class research infrastructure, while promoting international scientific cooperation. SESAME is a light source, based on a particle accelerator, that uses electromagnetic radiation emitted by electron beams. The experiments at SESAME will enable research in fields ranging from medicine to biology, materials science, physics and chemistry for health, environment,more...http://home.infn.it/newsletter-eu/pdf/NEWSLETTER_INFN_31_inglese_pag2.pdf
