Abstract: A device for detecting neutrons comprising a base, a lateral surface and a cover, thereby providing a detector housing having a central longitudinal axis, wherein the interior of the housing is divided into n (n≥2) cells wherein at least one of said cells is adapted to operate as neutron detection ion chamber by having at least one removable foil disposed parallel to said longitudinal axis, at least one removable foil positioned adjacent to, and essentially parallel with, a sector of the lateral surface, with said removable foils having neutron sensitive coating applied on at least one their faces, and an anode mounted in at least one cell bounded by said removable foils, with said housing constituting the cathode. The device is also useful for simultaneously detecting gamma irradiation and or producing radioisotopes.

Abstract: Various configurations of muon drift tubes for use in muon tomography are described and involve aluminum end caps coupled to an aluminum tube, an electrode in each of the end caps, and an anode wire extending between the electrodes. A two-part electrically conductive, gas-sealed, connection is located between an aluminum end cap and the aluminum tube. Methods of making those configurations of muon drift tubes are also described.

Abstract: The invention relates to a neutron detector unit for neutrons, in particular thermal and cold neutrons, comprising a detector housing (7, 17, 27), cathode elements and a plurality of anode elements (5, 15, 25), wherein in order to form a volume detector unit the anode elements (5, 15, 25) and the cathode elements enable a three-dimensional spatial resolution for conversion events, characterized by a converter gas in the detector housing (7, 17, 27). According to the invention, in a neutron detector arrangement which includes at least one neutron detector unit the neutron detector unit (3, 13, 23) or at least one of the neutron detector units (3, 13, 23) is oriented in such a way that at least some of the anode elements (5, 15, 25) of the at least one neutron detector unit (3, 13, 23) extend at least predominantly in a longitudinal orientation parallel or almost parallel to the direction of travel of the neutrons (4) to be detected.

Abstract: A system for assaying a sample for Molybdenum-99 content includes an inner ionization chamber including a well configured to receive the sample, an outer ionization chamber concentric with the inner ionization chamber, attenuating material positioned in the well, and a computing device. The computing device is configured to determine a first Molybdenum-99 content value of the sample based on a first current measured in the inner ionization chamber, determine a second Molybdenum-99 content value of the sample based on a second current measured in the outer ionization chamber, and determine a final Molybdenum-99 content value based on the first and second Molybdenum-99 content values.

Abstract: An energy-sensitive imaging detector for fast-neutrons includes energy-selective radiator foil stacks converting neutrons into recoil protons. The foils are separated by gas-filled gaps and formed of two interconnected layers: a hydrogen-rich layer such as a polyethylene layer for neutron-to-proton conversion, and a metal foil layer, such as an aluminum layer, defining a proton energy cut-off and limiting a proton emission angle. Energetic recoil protons emerging from the radiator foil release electrons in surrounding gas in the gaps. An electric field efficiently drifts the electrons through the gaps. An electron detector with position sensitive readout, based on Micro-Pattern Gaseous Detector technologies (such as THick Gaseous Electron Multipliers—THGEM) or other measures provides electron amplification in gas. The charge detector has a dedicated imaging data-acquisition system detecting the drifted electrons thereby sensing the position of the original impinging neutrons.
