Abstract

A first comparison has been made between the pulse-shape discrimination characteristics of a novel 4He-based pressurized scintillation detector and a NE-213 liquid-scintillator reference detector using an Am/Be mixed-field neutron and gamma-ray source and a high-resolution scintillation-pulse digitizer. In particular, the capabilities of the two fast neutron detectors to discriminate between neutrons and gamma-rays were investigated. The NE-213 liquid-scintillator reference cell produced a wide range of scintillation-light yields in response to the gamma-ray field of the source. In stark contrast, due to the size and pressure of the 4He gas volume, the 4He-based detector registered a maximum scintillation-light yield of View the MathML source to the same gamma-ray field. Pulse-shape discrimination for particles with scintillation-light yields of more than View the MathML source was excellent in the case of the 4He-based detector. Above View the MathML source its signal was unambiguously neutron, enabling particle identification based entirely upon the amount of scintillation light produced.
