Paper Abstract

An array of nine 811 cm3 LaBr3:Ce crystals coupled to photomultiplier tubes is used to detect γ rays induced from materials by neutrons emitted from a Deuterium-Tritium neutron generator. The accompanying digital data acquisition system has been developed to understand operational limits for remote detection of explosive contraband and analysis of material composition. Results are presented demonstrating current system performance, with the eventual goal of detecting a small (less than 5%) change in the composition of a material. Improvement expected over existing analog data collection systems are described along with discussion of the enhancements.
