Abstract
Abstract The Neutrons For Science (NFS) facility will provide intense neutron beams in the energy range between 1 MeV and 40 MeV. The neutron monitoring will be ensured by a detector consisting of a glass cell containing EJ309 liquid scintillator coupled to a photomultiplier. The goal of this study was the characterization of this monitor. Two experiments were performed to measure the light response of the scintillator from 3.6 MeV to 45 MeV as well as the detection efficiency between 3.6 MeV and 15.9 MeV. The obtained light response was used to adapt the simulation program SCINFUL to EJ309 scintillator. SCINFUL was then used to reproduce within 5 percent uncertainty the detector efficiency determined experimentally.
