Abstract
The DIAMINE sensor makes use of the neutron backscattering techniques (NBT). The presence of a buried land-mine causes a localized strong increase of the yield of low energy neutrons, due to the hydrogen content of the explosive and of the plastic case of the mine. In some conditions, the hit distribution could provide an "image" of the hidden object. Coupling of the NBT sensor with a metal detector (MD) will provide the operator with a compact device, reducing the false alarm rate of the single sensors. The laboratory tests of the DIAMINE system demonstrate the possibility to detect small APM up to 10 cm depth in sand. The best use of the NBT technique is presented in the frame of the Humanitarian De-mining requirements.
