SOLEIL ("Sun" in French) is a synchrotron facility near Paris, France. It performed its first acceleration of electrons on May 14, 2006. The name ''SOLEIL'' is a backronym for ''Source optimisée de lumière d’énergie intermédiaire du LURE'' (LURE optimised intermediary energy light source), LURE meaning ''Laboratoire pour l'utilisation du rayonnement électromagnétique''. The facility is run by a civil corporation held by the French National Centre for Scientific Research (CNRS) and the Commissariat à l'Énergie Atomique (CEA), two French national research agencies. It is located in Saint-Aubin in the Essonne département, a south-western suburb of Paris, near Gif-sur-Yvette and Saclay, which host other facilities for nuclear and particle physics. The facility is a member of the UniverSud Paris. SOLEIL also hosts (IPANEMA, the European research platform on ancient materials (archaeology, palaeontology, past environments and cultural heritage) ), a joint CNRS / French Ministry of Culture and Communication research unit. ==Main parameters== SOLEIL contains electrons travelling with an energy of 2.75 GeV around a 354 m circumference. It takes the electrons 1.2 μs to travel around this ring at almost the speed of light; 847,000 times per second.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SOLEIL」の詳細全文を読む スポンサード リンク
