SOLEIL, an acronym for “Optimized Source of LURE* Intermediary Energy Light,” is a research center located on the Plateau de Saclay in Saint Aubin, Essonne. More concretely, it is a particle (electron) accelerator that produces the synchrotron radiation, an extremely powerful source of light that permits exploration of inert or living matter.

Our division recruited scientists specialised in imaging, spectroscopy, to prepare the access of our teams to the Synchrotron beamlines.

What is SOLEIL

SOLEIL is a light source, a large lamp (150 m in diameter) that produces infrared, UV rays, and X-rays to explore matter at the atomic level—the aging of chocolate, the baking of bread, the effect of cosmetics on skin, control of plastic bottles, or the treatment of pollutants and the development of new medications.

SOLEIL is a source of light endowed with extraordinary and necessary properties for the scientific community (great brilliance: 10,000 times brighter than sunlight), a wide spectral “white” source range ranging from infrared (1eV) to hard X-rays (50 keV), polarization (linear, circular, etc.), and pulsed light. It provides new perspectives in the study of matter with a resolution down to millionths of meters and sensitivity to all types of materials.

The beam lines

Since the requests to use the machine outnumber its capacity, they are chosen by a committee on the basis of their scientific interest. The CEPIA Division has recruited engineers specialised in imaging and spectroscopy whose mission is to help INRA scientists to build these types of projects.

They focus on three light lines, in particular:

    LUCIA © V. Moncorgé/SOLEIL © © V. Moncorgé/SOLEIL, © V. Moncorgé/SOLEIL
    LUCIA
    is characterized by the production of a microfocused beam (3 x 3 µm²) in the 0.8-8 keV energy range. The spatial stability of the beam spot over a wide spectral range enables elemental distribution studies by micro-fluorescence X-ray spectroscopy (µ-XRF) as well as elemental speciation by X-ray absorption spectroscopy (XANES and EXAFS) in heterogeneous samples.

    NANOSCOPIUM
    is the multimodal and multi-length-scale beamline dedicated to scanning X-ray micro- and nanoprobe experiments (30 nm -1 µm spatial resolution range) in the 5-20 keV energy range. X-ray fluorescence (XRF), absorption spectroscopy (XAS), and phase-contrast imaging techniques can provide simultaneous information on the elemental distribution and speciation and on the sample morphology, both in 2 and 3D
  • DISCO © V. Moncorgé/SOLEIL. © © V. Moncorgé/SOLEIL, © V. Moncorgé/SOLEIL
    DISCO © V. Moncorgé/SOLEIL © © V. Moncorgé/SOLEIL, © V. Moncorgé/SOLEIL
    DISCO is the beamline covering the range from VUV to that of visible light.
    It is devoted to imaging and biospectroscopies that can be applied to biochemistry, chemistry and cell biology. Its spectral range is optimised at between 60 to 700nm with conservation of natural light polarisation.

Our teams have thus collected new data on the structure of plant tissues and organs, raw materials and processed foods - milk, foams, meat products, cereals, bread, wine, etc. - that help to characterise their quality.
