Abstract: A fissile neutron detection system includes a neutron moderator and a neutron detector disposed proximate such that a majority of the surface area of the neutron moderator is disposed proximate the neutron detector. Fissile neutrons impinge upon and enter the neutron moderator where the energy level of the fissile neutron is reduced to that of a thermal neutron. The thermal neutron may exit the moderator in any direction. Maximizing the surface area of the neutron moderator that is proximate the neutron detector beneficially improves the reliability and accuracy of the fissile neutron detection system by increasing the percentage of thermal neutrons that exit the neutron moderator and enter the neutron detector.

Abstract: A multi-resolution detector includes a high-resolution pixelated electrode and a low-resolution pixelated electrode. The high-resolution pixelated electrode includes a plurality of sub-arrays of first pixels. Each respective first pixel at each relative position in each sub-array is electrically connected in parallel with one another. The low-resolution pixelated electrode includes a plurality of second pixels. A control system receives as inputs an output from each pixelated detector. The control system uses the inputs to determine a physical position and a transverse intensity distribution of an incident charged particle pencil beam at the resolution of the high-resolution pixelated electrode.

Abstract: A radiation detection assembly includes an ionization chamber for detecting radiation. The ionization chamber includes a volume of pressurized gas. An exterior enclosure houses the ionization chamber within an interior volume. The exterior enclosure includes a frangible section. A relief assembly defines a gas flow path from the ionization chamber to the frangible section of the exterior enclosure. The frangible section releases pressure from within the ionization chamber when the pressurized gas within the ionization chamber exceeds a predetermined pressure such that at least some of the pressurized gas flows through the relief assembly and through the frangible section of the exterior enclosure. The pressurized gas is then released to an exterior of the exterior enclosure. A method of reducing pressure within a radiation detection assembly is also provided.
