Abstract

A photo-neutron source has been realized at the DaΦne Beam Test Facility: neutrons are produced by sending high energy electrons (510 MeV) to impinge on an optimized target. Neutron flux and spectra have been measured along well designed extraction lines. The experimental data have been compared with Monte Carlo predictions performed with FLUKA and MCNPX, respectively. The comparison between measured neutron rates, energy spectra and the correspective Monte Carlo expectations is presented, as well as the simulation results from the two different Monte Carlo codes are compared and analyzed.
