The Micro-Layered Fast-Neutron Detector (MLFD) is a proton-recoil fast-neutron scintillator that uses lucite as the hydrogen-rich neutron converter and silver-doped zinc sulfide (ZnS:Ag) as the inorganic scintillator medium. The MLFD is constructed by placing alternative layers of neutron converter and scintillation medium in order to maximize its light collection. A 43-mm long MLFD has previously shown a high detection efficiency of 9.2% for a bare 252Cf source, and exhibits acceptable gamma… Expand
