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. The scientific activity of the laboratory belongs to three sectors of equal importance: physicochemistry, structural studies and phase transitions, magnetism and supraconductivity.
