摘要： The present invention discloses a photoneutron source and a neutron inspection system. The photoneutron source comprises: an electron accelerating tube for accelerating an electron beam; an X-ray converting target, wherein the electron beam accelerated by the electron accelerating tube bombards the X-ray converting target to generate X-rays; a photoneutron target, wherein the X-rays enters the photoneutron target to generates photoneutrons; and a neutron modulation housing provided outside the photoneutron target, wherein the neutron modulation housing comprises a neutron collimation port for outputting photoneutrons. The present invention may directly output a desired neutron beam from the neutron collimation port of the photoneutron source.

摘要： The present disclosure provides a ray filter (10). The ray filter is arranged in front of an X-ray source and is switchable between a first state where the ray filter is configured to allow the high-energy X-rays and the low-energy X-rays to pass therethrough and a second state where the ray filter is configured to only allow the high-energy X-rays to pass therethrough. The present disclosure further provides a dual-energy X ray inspection system comprising a dual-energy X-ray source and the ray filter. The ray filter of the present disclosure has a small volume, a simple configuration, and is easily applicable to the dual-energy X ray inspection system without changing arrangement of the inspection system.
