  • Patent number: 11754516
    Abstract: A neutron emission unit is configured to emit neutrons such that a center axis (Nh) of a neutron emission intersects a center axis direction of collimators (23a to 23e). A calculation unit is capable of generating information about an inspection object in the center axis direction of the collimators, based on position information of a neutron detector and/or position information of the neutron emission unit, information about an angle (?1) at which the center axis of the neutron emission intersects the center axis direction of the collimators, and a neutron amount detected by the neutron detector.

  • Patent number: 11747288
    Abstract: A non-destructive inspection system 1 includes a neutron radiation source 3 capable of emitting neutrons N, and a neutron detector 14 capable of detecting neutrons Nb produced via an inspection object 6a among neutrons N emitted from the neutron radiation source 3. The neutron radiation source 3 includes a linear accelerator 11 capable of emitting charged particles P accelerated; a first magnet section 12 including magnets 12a and 12b facing each other, the magnets 12a and 12b being capable of deflecting the charged particles P in a direction substantially perpendicular to a direction of emission of the charged particles P from the linear accelerator 11; and a target section 13 capable of producing neutrons N by being irradiated with the charged particles P that have passed through the first magnet section 12.

  • Patent number: 11614415
    Abstract: A non-destructive inspection system includes: a neutron emission unit 12 capable of emitting neutrons pulsed; a neutron detector capable of detecting the neutrons emitted from the neutron emission unit and penetrating through an inspection object; a storage unit storing attenuation information indicating a relationship between a material of the inspection object and attenuation of the neutrons; and a calculation unit capable of calculating distance information indicating a position of a specific portion in the inspection object in accordance with time change information which is information on a change over time in an amount of the neutrons detected by the neutron detector. The calculation unit is capable of generating information related to an amount of the specific portion from information based on the amount of the neutrons according to the time change information, using the distance information and the attenuation information.
