  • Publication number: 20110121179
    Abstract: A high strength window for a radiation detection system has a plurality of ribs comprising beryllium material. There are openings between the plurality of ribs. The tops of the ribs terminate generally in a common plane. The high strength window also has a support frame around a perimeter of the ribs. A layer of thin polymer film material is disposed over and spans the plurality of ribs and openings to pass radiation therethrough. A radiation detection system comprises a high strength window as described above and a sensor behind the window. The sensor is configured to detect radiation that passes through the window.

  • Publication number: 20100243895
    Abstract: A window for a radiation detection system includes a plurality of intersecting ribs oriented non-perpendicularly with respect to each other. The plurality of intersecting ribs defines non-rectangular openings therebetween. A support frame is disposed around a perimeter of the plurality of intersecting ribs. A film is disposed over and spans the openings to pass radiation therethrough. The film and the plurality of intersecting ribs are integrally formed from a same material including a polymer.

  • Patent number: 7737424
    Abstract: A high strength window for a radiation detection system includes a plurality of intersecting ribs defining a grid having openings therein with tops of the ribs terminate substantially in a common plane. The intersecting ribs are oriented non-perpendicularly with respect to each other and define non-rectangular openings. The window also includes a support frame around a perimeter of the plurality of intersecting ribs, and a film disposed over and spanning the plurality of intersecting ribs and openings. The film is configured to pass radiation therethrough. An associated radiation detection system includes a sensor disposed behind the window. The sensor is configured to detect radiation passing through the high strength window.

  • Patent number: 7709820
    Abstract: A window for a radiation detection system includes a frame with an aperture therein configured to receive radiation therethrough. A plurality of silicon ribs span the aperture and are carried by the frame. A coating substantially envelopes each of the plurality of silicon ribs. A thin film covers the aperture and is carried by the plurality of silicon ribs and is configured to pass radiation therethrough.

  • Publication number: 20080296479
    Abstract: A high strength window for a radiation detection system has a plurality of ribs comprising diamond material. The plurality of ribs defines a grid having openings therein. The tops of the ribs terminate generally in a common plane and the height of the ribs is sufficiently thin to allow some radiation to pass directly through the diamond material of the ribs. The high strength window also has a support frame around a perimeter of the grid. A layer of thin polymer film material is disposed over and spans the plurality of ribs and openings to pass radiation therethrough. A radiation detection system comprises a high strength window as described above and a sensor behind the window. The sensor is configured to detect radiation that passes thought the window.
