    Abstract: The image tube employs a novel combination of elements which allow for utilization of a highly efficient III-V transmission photocathode activated to achieve negative effective electron affinity. The construction of the tube is especially suited for the activation of photocathode to achieve negative effective electron affinity.

    Abstract: An image intensifier tube comprising a phosphor screen and a photocathode is provided with a wire mesh adjacent the phosphor screen. This provides an equipotential surface and allows the main part of the focusing of electrons from the photocathode to be carried out in a relatively weak electric field. This leads to a reduction in the length of the tube.

    Abstract: Apparatus for deriving diffractive rays by diffraction gratings which enables light measurement to be effected with high accuracy in addition to the feasibility of making the whole apparatus in a compact size. These features of the apparatus are obtained by the provision of a photoelectric element on the rear side of an index grating at a position in which it faces a movable scale grating with a small distance from this latter grating.

    Abstract: Apparatus for providing X-rays (11) to an object (12) in air. A lens (13) directs energy (14) from a laser (27) onto a target (15) to produce X-rays (11) of a selected spectrum and intensity. A substantially fluid-tight first enclosure (16) around the target (15) has a pressure therein substantially below atmospheric pressure. An adjacent substantially fluid-tight second enclosure (18) contains helium (24) at about atmospheric pressure. A wall (19) has an opening (20) large enough to permit X-rays (11) to pass through and yet small enough that gas (21) can be evacuated from the first enclosure (16) at least as fast as it enters through the opening (20) at the desired pressure. Intermediate enclosures (34, 34') at logarithmically increasing air pressures have similar openings (20', 20") in line with the opening (20) and a transparent portion (36) in the near wall (35) of the second enclosure (18). The target (15) is located close to the opening (20) and emits a substantial portion of the X-rays (11) through the opening (20) and (via 20',20",36) on toward the far wall (22) of the second enclosure (18) having a portion (25) that is highly transparent to them, so that the object (12) to which the X-rays (11) are to be provided may be located outside the second enclosure (18) and adjacent thereto and thus receive the X-rays (11) substantially unimpeded by air or other undesired intervening matter.

    Abstract: A flip-header for mounting a charge transfer device, such as CCD, CTD, seonductor diode arrays and the like, thereon to a ceramic tube base of an image intensifier tube and variations of the basic tube configurations to accommodate proximity focus of the photocathode and the charge transfer device. The flip-header with the charge transfer devices mounted thereon are separately prebaked at a lower temperature than the other portions of the tube assembly, namely the tube base, tube body, and the faceplate. The flip-header is then set inside the tube.

    Abstract: A photocathode internally processed image intensifier inverter tube includes a cathode housing having an outer side wall forming a cylindrical opening for connection to the photocathode of the inverter tube. The side wall forms a cylindrical cavity in which the photocathode is received. A pair of flat wall surfaces are formed in the side wall. The flat surfaces are spaced radially inwardly such that the distance from the surfaces to the center of the cylindrical opening is less than the radius of the cylindrical opening. A tubular processing side arm is attached from each flat wall surface and are used to introduce antimony and alkali metal vapor, under a vacuum into the cathode housing for the deposit of a photosensitive coating on the photocathode substrate. After forming the photosensitive surface, the side arms are sealingly pinched off at the ends thereof to maintain a vacuum inside the inverter tube. The flat surfaces are positioned relative to the outer side wall and the side arms extend a specified distance from the flat wall surfaces such that the arms do not extend beyond the diameter of the side walls forming the cylindrical opening.

    Abstract: An image intensifier tube of the proximity focus type has a transparent cathode window with a curved inner surface and an anode window formed by a fiber optics plate having an inner surface curved to be substantially complementary to the cathode window inner surface. The arrangement mitigates the so-called "chicken-wire" effect and other flaws inherent in intensifiers using fiber optics at both the cathode and the anode ends. It is cheaper in manufacture and may be made of smaller depth, thereby simplifying its incorporation in existing apparatus.
