Fédération Française de Diffusion Neutronique
The 2FDN federation was created to face the future challenges related to the changes of the French and European landscape in neutron scattering science.
The main objective of this research federation is to bring together all professionals working in the field of neutron scattering to define the contours of a future strategy around research using neutron scattering. This implies to keep and extend the current competences in order to answer the societal stakes through an excellent and innovative research and training, adapted to the mutation of the French and European neutron instruments, and to support the users’ needs.
The federation’s missions:
- Organize a common call for experimental proposals on the french beamtime
- Increase access for the French community to beam time, support development projects in neutron instrumentation
- Establish a roadmap for French neutronics
- Formation of the new generation of neutron scientists
- Meet the needs of the users represented by the Société Française de Neutronique

French-German round table discussion:
A summary can be found here (and a short version here) of this discussion on partnership opportunities between France and Germany in neutron science has been organized during the spring conference of the German Physical Society.
The ICONE project, for a national neutron scattering source based on a Hi-CANS, High Compact Accelerator-driven Neutron Source, is now in the phase of technical design report. You can follow the progress on the project website.
The Preliminary Project Summary is available for consultation by following this link.
