Patent number: 11885920Abstract: 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.Type: GrantFiled: September 16, 2021Date of Patent: January 30, 2024Assignee: Silverside Detectors, Inc.Inventors: Andrew Inglis, Alison Forsyth, Thomas Nadovich, Timothy Teal, Philip Taber, Hidefumi Tomita

Patent number: 11768301Abstract: A fissile neutron detection system includes an ionizing thermal neutron detector arrangement including an inner peripheral shape that at least substantially surrounds a moderator region for detecting thermal neutrons that exit the moderator region but is at least generally transparent to the incident fissile neutrons. A moderator is disposed within the moderator region having lateral extents such that any given dimension that bisects the lateral extents includes a length that is greater than any thickness of the moderator arrangement transverse to the lateral extents. The moderator can include major widthwise and major lengthwise lateral extents such that any given dimension across the lengthwise and widthwise lateral extents includes a length that is greater than any thickness of the moderator arrangement transverse to the lateral extents.Type: GrantFiled: June 14, 2021Date of Patent: September 26, 2023Assignee: Silverside Detectors Inc.Inventors: Andrew Inglis, Alison Forsyth, Zachary S.

Patent number: 11630223Abstract: 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.Type: GrantFiled: October 16, 2020Date of Patent: April 18, 2023Assignee: Silverside Detectors Inc.Inventors: Andrew Inglis, Zachary S.

Patent number: 10352563Abstract: The present invention concerns a flame detector with optical sensors situated within a housing, which is coupled to a signal collector and focuser enclosure. The enclosure includes a reflective surface or reflective surfaces generally oriented outwardly and in optical communication with the sensors through a shield window exposing the sensors; the shield window is situated between the enclosure and the housing of the flame detector. The enclosure may have a conical shape, a parabolic shape, and may include convex or concave surfaces that reflect emission signals from an emission signal source to the sensors in optical communication with the reflective surfaces. The enclosure is thus adapted to collect emission signals and narrow or focus a field of view of the sensors, thereby increasing a detection range between the flame detector and an emission signal source such as a flame source.Type: GrantFiled: August 30, 2018Date of Patent: July 16, 2019Assignee: Detectors, Inc.Inventor: Adam Lam
