Paper Abstract

Neutron detection efficiencies for a 4 (pi) plastic scintillator detector were calculated with the Monte Carlo code of Cecil et al for various threshold of 2.5, 5, 7.5, 10 and 20 MeVee, assuming an isotropic distribution of neutrons emerging form the center of the target. A good agreement between the data obtained from the reaction (pi) +4He yields pppn with 120 MeV pions and efficiency calculations has been found. Proton reaction losses for 15, 20 and 35 cm thick plastic detectors were calculated using the GEANT code for proton energies up to 150 MeV. Reaction losses were extracted from the simulated spectra. Our correction curve for proton reaction losses gives slightly higher values than the data of Measday and Serre and the calculation of Janni.
