Abstract: An electron discharge device of the type including an evacuated envelope having a longitudinal axis comprises a photoemissive cathode for providing electrons in response to radiation incident thereon and a charge coupled device spaced from the cathode. A plurality of washer-like focusing electrodes are disposed between the cathode and the charge coupled device for focusing electrons therebetween. Each of the electrodes has an electron aperture of progressively decreasing diameter. The electron aperture of the electrode adjacent to the cathode is larger than the electron aperture in the electrode adjacent to the charge coupled device. The electrodes provide a substantially spherical electrostatic field lens between the photoemissive cathode and the charge coupled device.

Abstract: A photomultiplier tube comprises an evacuated envelope having a photoemissive cathode therein. A cage assembly including an anode and a plurality of closely spaced dynodes are within the envelope. The anode has at least one support rod. Each of the dynodes has a pair of dynode tabs formed in the ends thereof. A pair of dynode support spacers having a plurality of stress isolation apertures and electrode support apertures formed therethrough are provided for supporting the dynodes and the anode. The dynode tabs and the anode support rod extend through the electrode support apertures. A plurality of deformable stress isolation eyelets comprising a tubular shank with a flare formed in one end of the shank are disposed within a different one of the stress isolation apertures. The flare diameter is greater than the diameter of the stress isolation apertures thereby retaining the eyelets within the apertures. A second end of the tubular shank, opposite the flared end, extends outwardly from the dynode support spacers. The outwardly extending end portion is crimped to lock the eyelets within the stress isolation apertures. Nickel leads are provided for flexibly interconnecting the crimped end portion of a different one of each of the eyelets to one end of each of the dynodes and to one end of the anode support rod. A stem closes one end of the envelope. A plurality of relatively stiff cage assembly support leads extend through the stem and are welded to the crimped end portion of the eyelets thereby firmly securing the cage assembly to the support leads and indirectly connecting the support leads to the dynodes and the anode.

Abstract: An improved photomultiplier tube comprises an evacuated envelope having a faceplate extending across one end thereof. A photoemissive cathode is disposed on the interior surface of the faceplate. A support electrode having a centrally located aperture therethrough is spaced from the faceplate. An electron multiplier assembly is attached to the support electrode. A focusing assembly is disposed about the centrally located aperture in the support electrode on a side of the support electrode opposite the electron multiplier assembly. The focusing electrode assembly comprises an insulating member having a generally tubular body with an interior surface and an exterior surface and having a proximal end and a distal end. A top-cap, having a substantially U-shaped cross-section including a flat central base and two mutually parallel projections at the ends of the base, is attached to the distal end of the insulating member. The parallel projections are directed toward the support electrode and extend along at least a portion of the interior and exterior surfaces of the insulating member. At least one antimony evaporator for forming the photocathode is disposed adjacent to the focusing assembly. One of the projections at the end of the top-cap shields the exterior surface of the insulating member from antimony deposition and thus prevents electrical shorting of the focusing assembly to the support electrode. The other projection shields the interior of the insulating member from impingement by photoelectrons from the photocathode and thereby prevents electrical charging of the insulating member. A focus potential is applied to the top-cap of the focusing electrode assembly to focus the photoelectrons into the electron multiplier assembly.

Abstract: An intensified charge-coupled image sensor has a longitudinally extending optical axis. The image sensor comprises an image intensifier section and a header assembly. The image intensifier section includes an envelope having a photoemissive cathode therein for emitting photoelectrons in a pattern corresponding to the intensity of radiation incident thereon. The header assembly includes a charge-coupled device for receiving the photoelectrons from the cathode, an insulative header and a header flange attached between the insulative header and the image intensifier section. The header assembly is improved by the inclusion of an annular support flange which is coaxially disposed within the header flange. The support flange has a projection that abuts the insulative header. A charge-coupled device support assembly is eccentrically disposed within and attached to the annular support flange. The support assembly includes a lower support member and an upper tensioning member for tensioning the charge-coupled device and for exposing at least a portion of the device to the photoelectrons from the cathode through an aperture formed in the upper tensioning member. The exposed portion of the charge-coupled device is centered about the optical axis of the image sensor.
