    摘要： A photoneutron conversion target for generating photoneutrons by directing an x-ray beam at the photoneutron conversion target includes an elongated body having a first end and a second end. When the photoneutron conversion target is in use, the x-ray beam enters the body and propagates in a direction from the first end to the second end. The body of the photoneutron conversion target is shaped such that propagation of the x-ray beam is substantially proportionate to an intensity distribution of the x-ray beam, so that the greater an intensity of x-rays of the x-ray beam, the greater the propagation distance of the x-rays within the body of the photoneutron conversion target. The photoneutron conversion target according to the invention can make full use of the x-ray beam so as to increase a yield of photoneutrons.

    摘要： A method and a system for contraband detection in an object using photoneutrons and x-rays includes an x-ray generator that generates an x-ray main beam including a first x-ray beam and a second x-ray beam, the first x-ray beam being directed to pass through the object. A photoneutron conversion target is arranged to receive the second x-ray beam so as to generate photoneutrons, the photoneutrons being directed to enter the object and react with the object to emit characteristic γ-rays. An x-ray detecting arrangement is arranged to receive the first x-ray beam that has passed through the object in order to perform x-ray imaging detection of the detected object. A γ-ray detecting arrangement is arranged to receive the characteristic γ-rays in order to perform neutron detection of the object based on the characteristic γ-rays. The x-ray imaging detection and the neutron detection are simultaneously performed.

    摘要： Disclosed is a method of discriminating materials by employing fast neutron and continuous spectral X-ray and an equipment for the same. The method comprising the steps of: (a) transmitting a fast neutron beam produced by a fast neutron source and a continuous spectral X-ray beam produced by a continuous spectral X-ray source through inspected objects; (b) directly measuring the intensity of the transmitted X-rays and the intensity of the transmitted neutrons by a X-ray detector array and a neutron detector array respectively; and (c) identifying the materials of the inspected object by Z-dependency curves formed by the attenuation differences between the neutron beam and X-ray beam transmitted through different materials of the inspected object. This direct measurement of transmitted dual-ray technique has much more efficient than secondary radiations measurement such as neutron activation analysis, has much more material discrimination sensitivity than dual-energy x-ray technique. The respective measurements of neutrons and x-rays make the usages of high detect efficiency neutron detectors and x-ray detectors possible. The using continuous spectral x-ray produced by Linac adds more advantages such as: high penetration ability, high spatial resolution, and high image quality over monoenergetic dual-ray technique.
