Abstract

The invention discloses a neutron back scattering imaging device for plastic mine detection. The device comprises a position sensitive detector, a low energy neutron absorbing layer, a reflector, a shield, a stainless steel structure, a source strength monitoring detector, a neutron generator sealing component and a flexible high voltage cable. The position sensitive detector is located at the bottom end of the device, and the low energy neutron absorbing layer abuts against an upper surface and a side surface of the position sensitive detector; the neutron generator sealing component is located at the center of the device and is powered by the flexible high voltage cable; the reflector and the shield are sequentially wrapped at the outside of the neutron generator sealing component and are carried in the stainless steel structure; and the source strength monitoring detector is embedded from the top into the interior of the reflector. The device has two detection modes, that is, counting and imaging, fast early warning can be achieved in the counting mode, accurate identification of shape, size, embedding distribution, explosive content and other information of the mine can be achieved in the imaging mode, so that the false alarm rate of mine detection can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of nuclear radiation detection and radiation imaging, in particular to the technical field of neutron detection and neutron imaging, and specifically relates to a neutron backscatter imaging device for plastic mine detection. Background technique [0002] The variety of landmines and the complicated background of laying mines make mine detection very difficult. The effective detection and accurate identification of landmine targets has always been a worldwide problem recognized by the international community. At present, the relatively mature mine detection technologies in the world mainly include: metal mine detection, sonic mine detection, radar mine detection and infrared mine detection. These technologies have achieved rapid detection of some landmines to a certain extent by detecting the metal components in the shell of the landmines, or by using the differences in the characteristics of the landmines ...
