Scientific Description
SOLEIL is the French third generation synchrotron facility, operating at 2,75 GeV. 26 beamlines are open to users in 2013, in surface and material science (with emphasis on micronano-spectroscopies, high resolution, magnetism, chemistry), environmental and earth science, very dilute species and biology (crystallography, absorption, small angle scattering, fluorescence, IR microscopy). Areas of excellence are time resolved experiment both in X-ray range (diffraction, photoemission) and in the soft X ray energy range (coincidences spectroscopies at ultrahigh resolution), an extensive use of adjustable photon polarisations (dichroism studies), fully automated protein crystallography beamlines, etc. The 2 last beamlines (‘Nanoscopium’ and ‘Nanotomo’, under construction) will reinforce the SOLEIL capabilities in 2D and 3D imaging (from C Kedge up to 60 keV).About 70% of the available beamtime (5.500 h/y) is allocated to users on the basis of an international peer reviewing-based selection. Since 2008 SOLEIL has welcomed more than 4800 users. More than 25% of the proposals are already originating from non-French users, which show the attractiveness of SOLEIL towards international communities. SOLEIL is partner of other FP7 programs (Research Infrastructures, Marie-Curie actions) which are complementary to the present one. SOLEIL users and research staff produce about 300 papers per year in international scientific journals. SOLEIL is managed as part of a French public company.The members of the SOLEIL Synchrotron company are the CNRS and the CEA.

GRIVAL (Group of Industrial Relations and Valorization)

The GRIVAL is an interface's service in charge of coordinating the technical support and scientific expertise related to the demands coming from industrial partners in terms of: - confidential research programs - access to the beam for experiments - technology transfers The GRIVAL manages the patent port-folio of SOLEIL and controls the intellectual property conditions of all partnerships involving the SOLEIL research teams.

IPANEMA (European Research Platform in Ancient Materials)

IPANEMA is a service and research platform dedicated to ancient materials (archaeology, cultural heritage, paleontology and paleoenvironments) currently under development at SOLEIL. The project includes the construction of a dedicated building (in progress) and a new synchrotron beamline optimized for ancient materials that will complement the facilities already at SOLEIL. The group, brought together within the IPANEMA CNRS unit, is at the moment occupying temporary premises at SOLEIL, and has supported the synchrotron work since 2008 while also developing transverse methodological research. A dedicated building is under construction for hosting the team by the end of 2013.


The NANoSCoPium and NANoTomoGRAPHY “long” beamlines will be dedicated to state of the art hard coherent X-ray nano-imaging techniques. A 2,200 m2 extension to the Soleilexperiment hall will be built during 2012, to accommodate these beamlines.


The goal is to produce more pulsesshorter than 100 fs in the field of X-rays with photon flux of about 106 photons perpulse and a repetition rate of 10 kHz. To produce this type of pulse is made to interact oneelectron bunch (of length 20 to 100 ps) oscillating in the wiggler (of the future line PUMA) and a laserinfra-red (IR) of very short pulse duration (50 fs). Modulation energy of a small slice("slice") of the electron bunch is then induced. The electrons that are in this range have an energygreater than the energy dispersion of the electrons of the other package and then follow an orbit different wherever the dispersion is non-zero. It then becomes possible to select the radiation fromthis small slice when these electrons pass in an insertion or a bending magnet.The Femto-SLICING facility will be operational by the beginning of 2013 on the CRISTAL and TEMPO beamlines in a first time and then on the DEIMOS and GALAXIES beamlines in a second period.
