Post Helium-3 Neutron Detection at BYU

ORAL

Abstract

Development of spectrometers for studying low flux neutrons mixed in a field of gamma and cosmic rays has continued at BYU since 1982. As $^{3}$He, the archetypal neutron detector medium, becomes scarcer, BYU and associates have been pursuing technologies that may serve as acceptable detectors, even for low energy fission neutrons. Presented will be 1) some technologies: typical $^{3}$He safeguard monitoring equipment, capture gating techniques, multi-pulse discrimination, and hybrid developments; 2) some tools: low room-return lab, LANL LANSCE time of flight, and fission spectroscopy; 3) and some lessons learned: PMT timing disparity, plastic non- linearity, and pulse fragmentation.
