Les neutrons permettent de sonder la matière et leur sensibilité aux éléments légers et au magnétisme en font une sonde unique et originale. A l'IRAMIS , l’utilisation de la spectrométrie neutronique dans divers domaines de la recherche fondamentale et appliquée est développée au Laboratoire mixte CEA-CNRS Léon Brillouin à Saclay.

Diffusion des Rayons X aux petits angles / Small Angle X-Rays Scattering (SAXS)
X-rays are used to investigate the structural properties of solids, liquids or gels. Photons interact with electrons, and provide information about the fluctuations of electronic densities in heterogeneous matter. A typical experimental set-up is shown on Figure : a monochromatic beam of incident wave vector is selected and falls on the sample. The scattered intensity is collected as a function of the so-called scattering angle 2 teta.

Neutron diffusion make possible to probe the matter and its sensitivity to the light elements and to magnetism make it a single and original probe. Within IRAMIS, neutron spectrometry is used in various fields in fundamental and applied research and is developed around the CEA-CNRS Laboratory Leon Brillouin (LLB) around the Orphée reactor in Saclay. Neutrons are mainly intended for the study of condensed matter.
