Results of the Development of Humanitarian Landmine Detection System by a Compact Fusion Neutron Source and Dual Sensors

A 5-year task is described on the research and development of the advanced humanitarian landmine detection system by using a compact discharge-type fusion neutron source called IECF (Inertial-Electrostatic Confinement Fusion) device and 3 dual sensors made of BGO and NaI(Tl). With 107 D-D neutrons/s...

Description
Summary:A 5-year task is described on the research and development of the advanced humanitarian landmine detection system by using a compact discharge-type fusion neutron source called IECF (Inertial-Electrostatic Confinement Fusion) device and 3 dual sensors made of BGO and NaI(Tl). With 107 D-D neutrons/s stably produced in steady-state mode, H-2.2 MeV, N-5.3, 10.8 MeV g rays from (n,g) reaction with hydrogen and nitrogen atoms in the explosives are measured for two kinds of explosives (TNT, RDX), under the conditions of three different buried depths, and soil moistures each. Final probabilities of detection for arid soil are found to be 100% in the present tests. The neutron backscattering method is also found to be efficient.
