  • Publication number: 20210168925
    Abstract: A target structure includes a target and a cooling portion. The target generates neutrons by being irradiated with a charged particle beam. The cooling portion includes a front surface and a back surface that face to sides opposite to each other. The target is joined directly or indirectly to the front surface. A flow path for flowing of cooling liquid including hydrogen elements is formed in the cooling portion. When viewed in a thickness direction of the cooling portion from the front surface to the back surface, the flow path is positioned off a center portion of the target.

  • Publication number: 20210131981
    Abstract: The non-destructive inspection method includes: a water absorbing or drying step of changing a water-content state of a test piece; a transmission image capturing step of irradiating, with a radiation, the test piece absorbed water or dried for a predetermined time in the water absorbing or drying step and capturing a transmission image created by visualizing the radiation transmitted through the test piece; and an evaluation step of evaluating the test piece on the basis of the water-content state of the test piece determined from the transmission image captured in the transmission image capturing step.

  • Publication number: 20210033542
    Abstract: A nondestructive inspection apparatus makes a neutron beam incident on an inspection target, detects a specific gamma ray deriving from a target component in the inspection target, among gamma rays generated by the neutron beam, and determines a depth at which the target component exists, based on a result of the detecting. The nondestructive inspection apparatus includes a neutron source that emits a neutron beam to a surface of the inspection target, a gamma ray detection device that detects, as detection intensities, intensities of a plurality of types of specific gamma rays whose energy differs from each other, and a ratio calculation unit that determines a ratio between the detection intensities of a plurality of types of the specific gamma rays.

  • Patent number: 10241061
    Abstract: A non-destructive inspection device 10 using backscattering of neutrons includes a neutron source 3 that radiates a pulse neutron beam to a surface 1a of an inspection target 1, a neutron detection device 5 that detects scattered neutrons scattered in the inspection target 1 and returned, and a measurement device 7 that measures the detection number of scattered and returned neutrons detected by the neutron detection device 5 and generates detection number data expressing the detection number with respect to time.
