"The SOLEIL Synchrotron Facility in France"

Paul Dumas,
Synchrotron SOLEIL, L'Orme des Merisiers, Saint-Aubin, France



SOLEIL is one of the latest third generation synchrotron facilities to be completed and made operational for the General User community.  It officially welcomed first users early in 2008 and has 12 operational beamlines ( Phase I).


SOLEIL is a 2.75 GeV storage ring, located at Gif Sur Yvette, about 40kms South west of Paris, very near the location of the previous LURE facility.  With a horizontal emittance of 3.7 10-9 m.rad and a vertical emittance of 37 10-12 m.rad, SOLEIL is one of the brightness synchrotron facilities for this energy range.


Details of the storage ring will be presented, as will details of the operational beamlines, which include protein crystallography, EXAFS, diffraction and absorption, photoemission and photodiffraction, VUV and infrared.  We will also discuss the performance of SOLEIL with regard to beam stability.


SOLEIL can accommodate a total of 21 beamlines on undulators, and a further 22 on bending magnets, of which 24 are planned from core-funding.  The undulator beamlines reach a brightness in the order of 1020 ph/sec/mm2/mrad2 at 1 keV and 5 1019 at 13 keV on high harmonics.


The main scientific highlights of these beamlines, after one year of operations will be shown.


The current situation is that the Phase II beamlines are almost complete, and several of them will welcome their first users in July this year. They will be detailed.


Finally we will present details of the final phase of the user facility construction.  The experimental portfolio at SOLEIL will be completed mainly with nanofocusing /imaging and slicing stations.
