The method determines the position of the photoneutron rays based on the position of a neutron collimator, so as to overcome the problem of incapability of imaging due to loss of position information of the photoneutrons during moderation thereof. The method also images the object by arranging detector module arrays.

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 photoneutron-x ray source includes a photoneutron conversion target, which outputs both photoneutrons and x-rays simultaneously. The photoneutron-x ray source includes an x-ray generator for generating an x-ray main beam that is applied to the photoneutron conversion target. The photoneutron conversion target generates photoneutrons upon the application of the x-ray main beam to the photoneutron conversion target. The photoneutron conversion target has a body that defines a passageway extending through the body and that is structured such that a first x-ray beam of the x-ray main beam can pass through the passageway without any reaction with the body, while a second x-ray beam of the x-ray main beam can enter the body and react with the body to emit the photoneutrons.
