Latest Patents

One of his latest patents is for a panel type radiation image intensifier. This invention features a multistage, proximity type radiation image intensifier tube that boasts improved performance characteristics and a more rugged construction. The scintillator assembly consists of a first ceramic, cellular substrate that defines an array of hexagonally shaped cells. The cell walls taper to an edge and are coated with a conductive material such as aluminum. The cells are filled with a scintillation material like cesium iodide. Additionally, a first flat photocathode is positioned adjacent to the first substrate. An intermediate assembly, spaced from the scintillator assembly, comprises a second ceramic, cellular substrate similar to the first. The cell walls are also coated with a conductive material such as aluminum. A support layer is mounted to the substrate on the end opposite the scintillator assembly. A first flat phosphor display screen is mounted to the support layer on a side internal to the second substrate. A second photocathode is provided adjacent to the second substrate. An output assembly, spaced from the intermediate assembly, consists of a third ceramic cellular substrate similar to the first and second substrates. The cell walls are coated with a conductive material such as aluminum. A second flat phosphor display screen is mounted to the third substrate on the end opposite the second substrate. An output window is mounted to the tube envelope and adjacent to the second display screen. The design includes means for applying separate electrostatic potentials between the various substrates.
