Abstract

A gamma-ray imaging system, based on fast inorganic scintillation materials, is discussed in the context of the ranged sensing of high explosives and other organic materials. Methods by which one may enhance the spatial resolution of the detecting medium are outlined, and numerical simulations of the imager´s operation are presented. For ranged sensing applications, large neutron fluxes (>10¹² n/s) and sizable detector areas permit the rapid accumulation of informative data sets.
