The CEA and the CNRS have launched the design of a new high-brightness compact neutron source (HiCANS) based on a medium-energy proton accelerator: the ICONE project [1]. The long-term objective is to build a facility offering an instrumental suite of around ten spectrometers for the French and European scientific community. The project is currently in the Technical Design Report phase. This steppar fott - Thèses hors de l'EDPIF
