Located at Saint-Aubin (the Essonne, France,), the synchrotron SUN (Optimized Source of Light of Intermediate Energy of the ERUL) is a Synchrotron of third generation optimized in the range of the average X-rays, inaugurated on December 18th, 2006 by Jacques Chirac. Its brightness and its spectral range of compromise, of the Infra-red remote to hard x-rays, will enable him to cover a broad experimental range: fluorescence, absorption and diffraction of x-rays, infra-red spectromicroscopy, ultra-violet-visible spectroscopy, etc SUN should thus render service to a great number of scientific communities: Physical, Biology, Chemistry, sciences of the ground and the universe… until the science of materials of the inheritance.
This synchrotron replaces in particular the installations of the ERUL (Laboratoire for the use of the electromagnetic radiation), located at Orsay, which closed on December 19th, 2003. The synchrotron was initially to be located at Caen, within GANIL, but a decision of the government of Lionel Jospin in 2000, sliced in favor of Saclay. A sharp polemic took place between part of the scientific community and the Minister for research Claude Allègre, strongly opposed to the project.
The first beam of the synchrotron was stored on June 2nd, 2006 and the first users are awaited for the beginning of 2008.
Administratively, the synchrotron SUN is an civil society, whose members are CNRS (72%) and ECA (28%). The Area Ile-de-France, the General advice of the the Essonne as well as the Région Centers are also strongly implied in the project, in particular by financing most of its construction.
Very large instrument of research to the service of the scientific community and industry, SUN is also a place of diffusion of the scientific culture. For this reason, SUN is visited () and also proposes teaching animations for the teachers and their pupils.
