Abstract

The effect of passive iron converters was investigated at energies of 20-140 MeV. An enhanced detection efficiency for neutron energies above 70 MeV was found using iron converters of 2-3 cm thickness. The experimental findings will be implemented in a high-efficiency large-area detector for neutrons in the energy range 100-200 MeV at the National Superconducting Cyclotron Laboratory.
