NFS (Neutrons For Science) is an experimental area of the Spiral2 facility (Ganil, France) that will provide high intensity neutron beams for energies ranging from 0.5 to 40 MeV. The neutrons will be created by collision of Spiral2 charged particles with carbon, beryllium or lithium targets, thanks to a key element of NFS, the converter. The design of this one is a real challenge because it has to withstand a high power deposited by Spiral2's intense beams. In this context, Irfu has designed and built a converter able to support a power of 2 kW. NFS neutron beams will provide information in an unexplored energy domain. Fundamental physics, nuclear reaction modelling and nuclear databases will thus benefit from a unique tool.

 

 

 

For many years, the SPhN Spallation group has been developing, in close collaboration with the University of Liège, a model describing spallation reactions, called INCL. Based on its remarkable performance in an international evaluation, this model has just been included in three of the major simulation codes used worldwide to model and design the facilities in which these reactions occur.
