Abstract

By adapting routines from existing simulation programs for the interaction of neutrons and gammas with organic scintillators, a code has been produced to calculate the response of multi-element detectors to neutrons below 200 MeV and gammas below 10 MeV. The approach for the gamma calculations is similar to the macroscopic model used for neutron interactions. To test the approximations concerning gamma multiple-scattering and electron range-energy relations, measurements were made for the response of plastic scintillators to gammas at energies up to 1.3 MeV. The measurements focus on count rates and light-output distributions, and their analysis includes discussions of energy-to-light conversion and detector resolution. All measurements and calculations are in good agreement. The conclusions are discussed in terms of calculations of detection efficiencies for neutrons at energies of 1–200 MeV.
