Publication number: 20110121179Abstract: 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.Type: ApplicationFiled: May 20, 2010Publication date: May 26, 2011Inventors: STEVEN D. LIDDIARD, KEITH W. DECKER, DEGAO XU

Publication number: 20100243895Abstract: 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.Type: ApplicationFiled: June 14, 2010Publication date: September 30, 2010Inventors: Degao Xu, Eric C. Anderson, Keith W. Decker, Raymond T. Perkins

Patent number: 7737424Abstract: 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.Type: GrantFiled: June 1, 2007Date of Patent: June 15, 2010Assignee: Moxtek, Inc.Inventors: Degao Xu, Eric C. Anderson, Keith W. Decker, Raymond T. Perkins

Publication number: 20080296479Abstract: 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.Type: ApplicationFiled: June 1, 2007Publication date: December 4, 2008Inventors: Eric C. Anderson, Raymond T.

Patent number: 7233647Abstract: A radiation window device to transmit radiation as part of an x-ray source or detector includes a support to be subject to a substantial vacuum, and an opening configured to transmit radiation. A film is mounted directly on the support across the opening, and has a material and a thickness selected to transmit soft x-rays. An adhesive directly adheres the film to the support. A coating covers exposed portions of at least one of the evacuated or ambient sides of the film, and covers a portion of the support surrounding the film. The support, film and adhesive form a vacuum tight assembly capable of maintaining the substantial vacuum when one side is subject to the substantial vacuum. In addition, the vacuum tight assembly can withstand a temperature of greater than approximately 250 degrees Celsius.Type: GrantFiled: April 25, 2006Date of Patent: June 19, 2007Assignee: Moxtek, Inc.Inventors: D. Clark Turner, Keith W. Decker, M. Christine Roberts, Robert N. Stillwell
