    Abstract: Fissionable materials are distinguished from other high-effective atomic number materials by producing dual-energy x-ray radiation sufficient to cause fission in fissionable materials and directing the dual-energy x-ray radiation sufficient to cause fission in fissionable materials towards a physical region. X-ray radiation and a product of fission from the physical region are sensed. An absorption of the dual-energy x-ray radiation by the physical region is determined based on the sensed x-ray radiation, and whether the physical region includes fissionable material is determined based on the presence of a product of fission.

    Abstract: A property of a treatment beam is controlled during a scanning period. A portion of a region is exposed to an imaging x-ray beam during a scanning period, the imaging x-ray beam being generated by an electron-beam scanner. X-ray radiation from the region is detected, the x-ray radiation representing an attenuation of the imaging x-ray beam caused by the portion of the region. A first image of the portion of the region is generated based on the detected x-ray radiation. A characteristic of the portion of the region is determined from the generated first image. An input derived from the characteristic is generated, the input configured to cause a source of a treatment beam to modify a property of the treatment beam. The source of the treatment beam modifies a property of the treatment beam during the scanning period by providing the input to the source of the treatment beam.

    Abstract: A source of pulsed radiation is coupled to a positionable filter. The positionable filter includes an element that produces an indication of a position of the filter. The source is configured to receive the indication of the position of the filter, and to regulate emission of a pulse of radiation based on the indication. A device includes an area including a material that alters a parameter of a beam of radiation that interacts with the material. The device is configured to move relative to a source of pulsed radiation. An element provides a signal to the source of pulsed radiation that indicates a position of the area relative to the source. The signal causes the source to trigger emission of a pulse at a time such that the emitted pulse is incident upon a portion of the area.

    Abstract: An angular analysis system that can be controlled to receive radiation at a defined angle from a defined focus region. The angular analysis system is used for level 2 inspection in an explosive detection system. Level 2 inspection is provided by a three-dimensional inspection system that identifies suspicious regions of items under inspection. The angular analysis system is focused to gather radiation scattered at defined angles from the suspicious regions. Focusing may be achieved in multiple dimensions by movement of source and detector assemblies in a plane parallel to a plane holding the item under inspection. Focusing is achieved by independent motion of the source and detector assemblies. This focusing arrangement provides a compact device, providing simple, low cost and accurate operation.

    Abstract: An object within a region is exposed to a first beam of penetrating radiation. The first beam of penetrating radiation is sensed on a side opposite the region from a source of the first beam. An attenuation of the first beam caused by passing the first beam through the object is determined, the attenuation is compared to a threshold attenuation. If the attenuation exceeds the threshold attenuation, a parameter of a second of beam of penetrating radiation is adjusted based on the determined attenuation.

    Abstract: A representation of an amount of energy incident on a radiation sensor formed from multiple sensing elements coupled together along a direction parallel to a direction of propagation of the incident radiation is received. The radiation sensor has an adjustable border positioned between any two of the multiple sensing elements. From the representation, an amount of energy incident on the radiation sensor is determined. A position of the border is selected based on the amount of energy incident on the radiation sensor. After selecting the position of the border, an absorption characteristic of a region imaged by the radiation sensor is determined.

    Abstract: A first pulsed beam of charged particles from a particle accelerator is accelerated toward a first target that is configured to emit a fast neutron beam in response to being struck by an accelerated particle such that the fast neutron beam is directed toward a physical region. The last neutron beam includes a neutron having an energy sufficient to cause fission in a fissionable material. Data from a sensor configured to detect radiation of a fission product is accessed, and before accelerating a second pulsed beam of charged particles, whether the physical region includes a fissionable material based on the data from the sensor is determined.
