Large Area Neutron Counter Array

NOVA Scientific will demonstrate a large-area/low-cost neutron detection system having high detector quantum efficiency and high signal-to noise ratio. The approach utilizes an embedded neutron absorber in a solid state detector, utilizing known processingtechnology. The system detects fissionable materials by converting the neutron signal into a large electron pulse. The unit is light for field deployment and assembly as a stand-alone unit. The modular approach permits tiling into large arrays formonitoring of thoroughfares and ports of entry having high volume traffic of cargo containers or trucks. The large area solid state unit can be flight certified and provides a substantially lower-cost alternative to 3He detectors. The proposed systemwill detect small quantities of special nuclear materials concealed in containers at port of entry, airports, and highway and city drive-throughs. Sensor arrays are two-man portable, relatively inexpensive, mass produced, can be flight certified, and canbe tiled into large areas. The modular unit can be self-contained with automatic signal processing electronics. Applications include Homeland Defense, Military Security, and monitoring of clandestine materials.
