Abstract

The invention discloses a photoneutron source and a neutron inspection system. The photoneutron source comprises an electron accelerating tube, an X-ray converting target, a photoneutron target and aneutron modulating housing, wherein the electron accelerating tube is used for accelerating an electron beam current; the electron beam current accelerated by the electron accelerating tube impacts the X-ray converting target to generate X rays; the X rays enter the photoneutron target and generate photoneutrons; the neutron modulating housing houses the outside of the photoneutron target, and comprises a neutron collimating opening for outputting the photoneutrons. According to the photoneutron source and the neutron inspection system, a required electron beam current can be directly output from the neutron collimating opening of the photoneutron source.

Description

technical field [0001] The invention relates to the technical field of radiation inspection, in particular to an optical neutron source and a neutron inspection system. Background technique [0002] When neutrons react with different elements, they emit photons of different characteristic energies. Based on the element content characteristics of specific substances and the reaction mechanism of neutrons and nuclei, by detecting the characteristic gamma energy spectrum of the detected substance, the elemental composition and the proportional relationship of each element are determined to distinguish explosives, drugs or general Organic matter, higher accuracy. For example, the element composition of explosives is usually C, H, N, O, and the content of N and O is relatively high, and the content of H and C is very small; in the preparation process of many drugs, the participation of chlorine-containing substances is required, therefore, Drugs / precursor substances can be dete...
