| titleOfInvention | Thermal neutron analysis mine detection device based on deuterium and deuterium neutron generator |
| abstract | The invention discloses a thermal neutron analysis mine detection device based on a deuterium and deuterium neutron generator. The device comprises a low-energy neutron absorber, a lead shield, a gamma detector, a source intensity monitoring detector, a neutron reflector, a neutron generator and a neutron moderator. The low-energy neutron absorber, the lead shield and the gamma detector are sequentially wrapped from outside to inside to form a detection unit with the lower end close to the neutron generator and the upper end far away from the neutron generator; the neutron generator is positioned in the center of the device, the neutron reflector wraps the side surface of the neutron generator, the neutron moderating body is tightly attached to the position right below the neutron generator, and the four detection units are uniformly and symmetrically distributed in four directions of the side surface of the neutron generator; the source intensity monitoring detector is embedded into the reflector from the top. The device adopts deuterium and deuterium neutron generator as neutron source and adopts LaBr 3 And the (Ce) detector is used as a gamma detector, and the rapid detection and accurate identification of the mine target can be realized through the detection of the content abnormality of the nitrogen element. |
