A Micromegas detector was used in the neutron Time-Of-Flight (n-TOF) facility at CERN to evaluate the spatial distribution of the neutron beam as a function of its kinetic energy. This was achieved over a large range of neutron energies by using two complementary processes: at low energy by capture of a neutron via the Li-6(n, alpha)t reaction, and at high energy by elastic scattering of neutrons on gas nuclei (argon + isobutane or helium + isobutane). Data are compared to Monte Carlo simulations and an analytic function fitting the beam profile has been calculated with a sufficient precision to use in neutron capture experiments at the n-TOF facility.
