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 Island southern part is the location of a new luxurious neighborhood. Soleil is linked to the mainland by a causeway. Soleil Island Ile Soleil is a small artificial island (0.14 km²) in the Seychelles, lying 50m off the east coast of Mahé, near the runway of the Seychelles International Airport. The island was reclaimed in 2008 after the Dubai Dredger finished its work in the Victoria Port islands. The local Anse-aux-Pins mayor decided he wanted an artificial island as well. There are plans to build a new terminal on the island, due to housing problems. The island belongs to Anse-aux-Pins District.
