Abstract: The present invention provides a cellular thermal neutron detector, comprising: a cellular structure comprised of one or more hollow regular hexagonal prism-shaped cellular units, wherein a neutron absorbing material is coated on an inner side of a pipe wall of each of the cellular units. Since the neutron-sensitive cellular structure is employed, the present invention can perform thermal neutron detection without using the scarce nuclide 3He, and effectively reduce the manufacture costs of the thermal neutron detector. Further, the present invention has characteristics such as a reduced or eliminated neutron detecting dead zone.

Abstract: The present disclosure provides a dual-energy detection apparatus and method. The dual-energy detection apparatus includes an X-ray source configured to send a first X-ray beam to an object to be measured; a scintillation detector configured to work in an integration mode, and receive a second X-ray beam penetrating through the object to be measured to generate a first electrical signal; a Cherenkov detector configured to be located behind the scintillation detector, work in a counting mode, and receive a third X-ray beam penetrating through the scintillation detector to generate a second electrical signal; and a processor configured to output image, thickness and material information of the object to be measured according to the first electrical signal and the second electrical signal. The dual-energy detection method provided by the present disclosure may acquire an image of the object to be measured that is clearer and contains more information.
