Fast and thermal neutron measurements inside a fusion-oriented shielding mock-up

Year: 2025

Type: article

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 12 C ( n, α ) 9 Be ( Q = − 5 . 7 MeV) and 28 Si ( 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 6 LiF neutron absorbing layer. The experimental results are eventually compared with dedicated FLUKA-INFN simulations.
