The experimental setup called Medley, has been installed at the Neutrons For Science (NFS) facility at GANIL to study the production of light-ions in neutron-induced reactions. The setup was first used to measure the neutron spectral flux from neutron-proton elastic scattering, allowing both an assessment of its performance, and providing an independent measurement of the neutron flux of the facility. The experimental setup, its performance, and the challenges encountered are presented and discussed. The deduced neutron flux is compared to the one obtained from a monitor based on position-sensitive parallel plate avalanche counters (PS-PPACs).
