ABSTRACT:
A multistage, proximity type, radiation image intensifier tube having improved performance characteristics and more rugged construction is provided. A scintillator assembly is comprised of a first ceramic, cellular substrate defining 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 such as cesium iodide. A first flat photocathode is provided adjacent the first substrate. An intermediate assembly spaced from the scintillator assembly is provided comprised of a second ceramic, cellular substrate similar to the first. The cell walls are coated with a conductive material such as aluminum. A support layer is mounted to the substrate on an end opposite the scintillator assembly. A first flat phosphor display screen is mounted to the support layer on a side internal the second substrate. A second photocathode is provided adjacent the second substrate. An output assembly spaced from the intermediate assembly is provided and is comprised of a third ceramic cellular substrate which is similar to the first and second substrate. 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 an end opposite the second substrate. An output window mounted to the tube envelope and adjacent the second display screen is provided. Means are provided for applying separate electrostatic potentials between the various substrates.
