Description
The IFMIF-DONES facility will produce neutrons with energies up to 50 MeV and will be one of the most intense neutron source in the world in that energy range. Irradiations, to test fusion materials, will take place close to the Lithium target, in the high-flux test module (HFTM) where the maximum of flux is encountered. A large part of the neutrons will interact with the irradiated materials but most of them will just scatter-off or pass through the irradiation module and finish in the walls of the Test Cell.
With the possibility of creating a hole in the bioshield of the Test Cell, a continuous and collimated neutron beam of about 2.E10 n/cm²/s will be available in the adjacent hall dedicated to non-fusion experiments. The pre-design studies, based on Geant4 simulations, show that IFMIF-DONES has the potentialities to be a first class facility for techniques using fast neutrons and a medium-flux facilty for techniques using thermal neutrons.
