Fig. 9
The intensity ratio of neutrons escaped from different layers of the proton-based ANES to that of the GF-based ANES (per MW of the beam power). The energy of the proton beam used in the Geant4 simulations is 500 MeV, and the thicknesses of the LBE and Be layers are \(T_{\textrm{LBE}}=2\) cm and \(T_{\textrm{Be}}=16\) cm, respectively.
