Abstract

The effect of passive iron converters on the detection efficiency of neutrons in a plastic scintillator 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 results are compared to a simulation. 2002 Elsevier Science B.V. All rights reserved. PACS: 29.40.M
