Abstract
A stand for studying the characteristics of time-of-flight neutron detectors is described. Plastic scintillation detectors in the form of rectangular prisms with cross sections of 100 × 100 and 100 × 200 mm2 and lengths of 300, 400, and 500 mm are viewed through by photomultipliers from the two ends. The detectors are irradiated with a collimated 14-MeV neutron beam produced in the d + t → n+ 4He reaction. The collimated beam makes it possible to investigate the spatial resolution of long detectors. The interaction point is determined either from the arrival time of light pulses to the opposite ends of the scintillators or from the ratio of the amplitudes of the signals at the ends of the scintillators. The stand proposed also makes it possible to measure the absolute efficiency of detectors of different length at a neutron energy of 14 MeV.
