Neutrons
logo_tutelle logo_tutelle 

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 autour du Laboratoire mixte CEA-CNRS Léon Brillouin autour du réacteur Orphée à Saclay. Ils sont principalement destinés à l'étude de la matière condensée. L'activité scientifique propre du laboratoire peut se regrouper en trois secteurs sensiblement d'égale importance: la physico-chimie, les études structurales et de transition de phases, le magnétisme et la supraconductivité.
