Calibration of a modular plastic scintillator neutron detector in the kinetic energy range 100–500 MeV

Abstract We describe the calibration of a modular neutron counter for neutrons and protons of between 100 and 500 MeV kinetic energy. We present results for the detection efficiency, time and spatial resolution, and multifiring. We emphasise the necessity of calibrating the crosstalk between neutron and photon identification.
