The status of the Delft University Neutron Backscatter Landmine Detector (DUNBLAD)

The neutron backscattering technique may be applied to search for non-metallic landmines in relatively dry soils. A detector system using this technique has been constructed. Tests showed that anti-tank mines can reliably be found, but that, depending on the circumstances, anti-personnel mines may escape detection. A first test with a pulsed neutron generator shows that further improvements can be achieved by applying a window on the neutron transit time. (C) 2004 Elsevier Ltd. All rights reserved.
