A High Efficiency Fast Neutron Detector

Abstract

This report researches a concept for a high efficiency detector of fast neutrons (several MeV), using solid state charged particle detectors overlaid with thick disks (about mm) of 238U. Experiments show a significant count rate in our mock-up when exposed to a fast neutron flux, but it appears insensitive to the slow/thermal neutron flux. Our preliminary results indicate a system with an efficiency on the order of at least 5% could be developed. Keywords: Fast neutron; Fission; High efficiency; Neutron detectors.
