SOLEIL diffusion. 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. SOLEIL 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
Soleil Center As of 2018, the project has been cancelled, but there is a new 18 story Westin Hotel under construction on the same land. Soleil Center The Soleil Center was a 43-story skyscraper and condo-hotel planned for Raleigh, North Carolina, United States. The 480 ft (146 m) building was to be located next to the Crabtree Valley Mall on Glenwood Avenue (US 70) just north of the I-440 beltline, in an area variously known as "Midtown Raleigh" or "Uptown Raleigh". The Soleil Center was intended to be the second tallest building in Raleigh and in the Triangle region. The PNC Plaza
