Abstract
A Neutronics benchmark experiment was carried out at the Frascati Neutron Generator (FNG) operating at the ENEA Frascati research centre. The experiment aimed at using real-time neutron sensors to measure the spatial distribution of thermal and fast neutrons in a prototype shielding assembly exposed to 14 MeV fusion neutrons. The fast neutrons were measured exploiting the inelastic 12C(n, α)9Be (Q = − 5.7 MeV) and 28Si(n, α)25 Mg (Q = − 2.66 MeV) reactions in a bare Silicon Carbide (SiC) solid state detector. The thermal neutrons were measured using an identical SiC detector covered by a 6LiF neutron absorbing layer. The experimental results are eventually compared with dedicated FLUKA-INFN simulations.
