Abstract: A high efficiency UV responsive negative electron affinity photocathode with the long wavelength cutoff tunable over the wavelength from 200 to 300nm is based on Al x Ga 1-x N, Negative electron affinity photocathodes for sharply enhanced photoemission yield can be formed by applying a layer of cesium (15) to the surface of Al x Ga 1-x N (14) for which the Fermi energy level is appropriately positioned (Figure 1).

Abstract: A cold cathode field emission device having a cone shaped emitter (112, 208) formed with a substantially normal (but not absolutely normal) vapor deposition process (109) wherein the substrate (101, 201) need not be rotated with respect to the vapor deposition target. The vapor deposition process forms an encapsulating layer (111, 207) that can either be utilized as an electrode within the completed device, or that can be removed to allow subsequent construction of additional layers.

Abstract: A multistage, radiation image intensifier tube having improved performance characteristics and more rugged construction. The tube has a scintillator assembly (22) comprising a first ceramic, cellular substrate (26) defining an array of hexagonally shaped cells. The cell walls taper to an edge and are coated with a conductive material (28) such as aluminum. The cells are filled with a scintillation material (30) such as cesium iodide. A first flat photocathode (24) is provided adjacent the first substrate. An intermediate assembly (34) spaced from the scintillator assembly (22) is provided comprised of a second ceramic, cellular substrate (36) similar to the first. The cell walls are coated with a conductive material (38) such as aluminum. A support layer (40) is mounted to the substrate (26) on an end opposite the scintillator assembly (22). A first flat phosphor display screen (42) is mounted to the support layer (40) on a side internal the second substrate (36). A second photocathode (46) is provided adjacent the second substrate (36). An output assembly (48) spaced from the intermediate assembly (34) is provided and is comprised of a third ceramic cellular substrate (50) which is similar to the first and second substrates (26 and 36). The cell walls are coated with a conductive material (52) such as aluminum. A second flat phosphor display screen (58) is mounted to the third substrate (50) on an end opposite the second substrate (36). An output window (56) mounted to the tube envelope (12) and adjacent the second display screen (58) is provided. Means (62) are provided for applying separate electrostatic potentials between the various substrates (26, 36, 50).
