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
Cité Soleil members in Port-au-Prince, but since then the atmosphere there has not improved; the armed roadblocks and barbed wire barricades have not been removed. After four people were killed and another six injured in a UN operation exchange of fire with criminals in Cité Soleil in late January 2007, the United States announced that it would contribute $20 million to create jobs in Cité Soleil.
