  • Explosives detection by directional fast neutron beams scan with associated particles
    Patent number: 7420175
    Abstract: This invention is related to equipment and techniques for fast neutron activation analysis of explosives and /or other warfare agent. The techniques are based on 14 MeV fast neutrons from D-T fusion reaction, the kinematics of the nuclear reaction and fast coincidence between ?-particles of the D-T reaction and ?-quanta from fast neutron induced reactions. A fast neutron generator with effective target cooling and different operation modes provides high neutron yield, long life, and simple maintenance of the equipment and good geometric resolution of the directional neutron beam. High positional resolution of the directionally scanning neutron beam, high time resolution of the coincidence and high neutron yield provide the real time robust screen of explosives with high speed and/or high sensitivity, flexibility for big and small items and overall high probability of detection (PD) and low probability of false alarms (PFA). The remote video scan device also has zooming capability to change solid angle.
