Abstract :
We propose a model of currents induced by 14 MeV neutrons in dielectrics, which agrees well with observed data for the first time in the range of large fluxes (above 1018 n/cm2/s). We propose simple analytical model and numerical calculation using Geant4 consistent with experiments done at OMEGA Inertial Confinement Fusion facility.
