Numerous domains, in fundamental research as well as in applications, require the study of reactions induced by neutronswith energies between a few MeV and a few tens of MeV. Reliable measurements are necessary to improve the evaluated databases used by nuclear transport codes. It concerns a large number of topics like transmutation of nuclear waste, design of future fission and fusion reactors, nuclear medicine or test and development of new detectors. A new facility called Neutrons For Science (NFS) has been built for this purpose on the GANIL site at Caen (France). NFS is composed of a pulsed neutron beam for time-of-flight measurements and irradiation stations for cross-section measurements. Neutrons will be produced by the interaction of deuteron and proton beams, delivered by the SPIRAL-2 linear accelerator, with thick or thin converters made of beryllium or lithium. Continuous and quasi-mono-energetic spectra will be available at NFS up to 40 MeV. In this fast energy region, the neutron flux is expected to be up to 2 orders of magnitude higher than the one of the others existing time-of-flight facilities. In addition, irradiation stations for neutron-, proton- and deuteron-induced reactions will allow performing crosssection measurements by the activation technique. After a description of the facility and of its characteristics, the experiments to be performed in the short and medium term will be presented.< Réduire
