چکیده انگلیسی
Time-of-flight measurements were conducted to characterize the neutron energy response of pressurized 4He fast neutron scintillation detectors for the first time, using the Van de Graaff generator at Ohio University. The time-of-flight spectra and pulse height distributions were measured. This data was used to determine the light output response function, which was found to be linear at energies below 3.5Â MeV. The intrinsic efficiency of the detector as a function of incident energy was also calculated: the average efficiency up to 10Â MeV was 3.1%, with a maximum efficiency of 6.6% at 1.05Â MeV. These results will enable development of neutron spectrum unfolding algorithms for neutron spectroscopy applications with these detectors.
