摘要：

Time-of-flight measurements were performed to determine the He-4 pressurized fast neutron scintillation detectors response function and the ability of the detectors to be applied as a spectrometer. An experimentally validated neutron energy response function was used in conjunction with an iterative least squares unfolding technique to unfold a(252)Cf spontaneous fission spectrum, a PuBe (alpha, n) spectrum, and a deuterium-deuterium (D-D) fusion reaction spectrum. The ability of the detectors to retain incident neutron energies makes them suitable for applications such as nuclear non-proliferation and spent nuclear fuel monitoring.
