Abstract: A radiation detection element includes a base material, a first electrode, a second electrode, a third electrode, a fourth electrode, a fifth electrode, a first external terminal, a second external terminal, a third external terminal, and a fourth external terminal. Each of the first external terminal, the second external terminal, the third external terminal, and the fourth external terminal is a solder ball, and the first external terminal, the second external terminal, the third external terminal, and the fourth external terminal are insulated from each other. A region provided on the first electrode, the second electrode, the third electrode, the fourth electrode, and the fifth electrode overlaps at least one of the first external terminal, the second external terminal, the third external terminal, and the fourth external terminal in a view vertical to the first surface side of the base material.

Abstract: A muon detector includes: a chamber having a maximum cross-sectional dimension of 30 cm or less; a gas sealed inside the chamber ionized by the passage of atmospheric muons to form ions in the chamber; a cathode in the chamber at a first position; an anode in the chamber displaced from the first position, the anode including a mesh of wires; a micropattern gaseous detector arranged between the cathode and the anode and proximate to the anode and configured to receive the ions formed in the chamber between the anode and the cathode and generate electrons in response to each ion sufficient to generate a current in one or more of the mesh wires of the anode; and readout electronics in electrical communication with the anode to detect signals in response to the current generated in the mesh wires.

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 narrow thermal neutron detector includes a slidably receivable ionization thermal neutron detector module within an overall housing body. An active sheet layer of the ionization thermal neutron detector module can be tensioned across its width. The ionization thermal neutron detector module can include module upper major surface extents and module lower surface extents such that, when installed within the housing body, the module upper major surface extents are in a first spaced apart confronting relationship with housing upper major surface extents to define a first clearance and module lower major surface extents are in a second spaced apart confronting relationship with housing lower major surface extents to define a second clearance to accommodate housing flexing due to ambient pressure change. The housing body can be formed with a single opening for receiving the ionization thermal neutron detection module or with opposing first and second opposing end openings.

Abstract: A system for detecting a position of an ionizing radiation. The system includes a radiation detector including a plurality of cathode films, a plurality of anode strips sets, a plurality of insulator films, a conductive grid, and a drift region. Each set of the plurality of anode strips sets is disposed between a respective pair of adjacent cathode films of the plurality of cathode films. Each of the plurality of insulator films is disposed between a respective cathode film of the plurality of cathode films and a respective set of the plurality of anode strips sets. The conductive grid is disposed in parallel with the detection plane and exposed to the ionizing radiation. A drift region includes a region between the conductive grid and the detection plane. The radiation detector is configured to ionize a gas by generating an electric field inside the drift region.
