Abstract

In the frame of direct dark matter search, the fast neutrons producing elastic collisions and solar neutrinos by coherent interactions on nuclei are the ultimate background. The MIMAC (MIcro-tpc MAtrix Chambers) project has developed a directional detector providing the directional signature to discriminate them based on 3D nuclear tracks reconstruction. The MIMAC team of the LPSC has adapted one MIMAC chamber as a portable fast neutron spectrometer, the Mimac- FastN detector, having a very large neutron energy range (10 keV – 200 MeV) with different gas mixtures and pressures. The present paper shows its main features and functionality and demonstrates its potential in the energy range from 1 MeV to 15 MeV.
