Abstract: A night vision system, a microchannel plate (MCP), and a planetary deposition system and methodology are provided for selectively depositing an electrode contact metal on one side of MCP channel openings. MCPs can be secured to a face of a platter that rotates about its central platter axis. The rotating platter can be tilted on a fixture surrounding an evaporative source of contact metal. A mask with a variable size mask opening is arranged between the rotating platter and the evaporative source. While the mask orbits around the evaporative source with the rotating platter, the mask does not rotate along its own axis as does the rotating platter. Depending on the opening of the non-rotating mask, and the tilt angle of the rotating platter, the respective circumferential distance around and the depth into the shaded first side of the channel opening is controlled.

Abstract: A detector includes: one or more electron emissive surfaces; first and second housing elements defining a space therebetween; and a deformable member or a deformable mass some or all of which occupies the space. The first and second housing elements and the deformable member or the deformable mass define on one side an environment internal the detector and on another side an environment external the detector. The deformable member or the deformable mass has a central region which when contacted by the first and/or second housing elements is deformed so as to inhibit or prevent passage of a gas through the space.

Abstract: Scalable electron amplifier devices and methods of fabricating the devices an atomic layer deposition (“ALD”) fabrication process are described. The ALD fabrication process allows for large area (e.g., eight inches by eight inches) electron amplifier devices to be produced at reduced costs compared to current fabrication processes. The ALD fabrication process allows for nanostructure functional coatings, to impart a desired electrical conductivity and electron emissivity onto low cost borosilicate glass micro-capillary arrays to form the electron amplifier devices.

Abstract: A focused electron/bombarded hybrid photomultiplier tube comprising a photocathode, focusing electrodes, and a collection anode disposed in a detector body. The collector anode includes a diode for receiving the focused output electron beam from the photocathode. The current gain between the photocathode output current and the detector output signal from the diode is over 1000 at a tube operating voltage of 7 kV. The noise factor has been determined to be 1.1. A hybrid photomultiplier tube includes a photocathode, a photodiode for collecting and multiplying electrons emitted by the photocathode and providing an output signal and electrodes for focusing the electrons on the photodiode. A vacuum envelope encloses a vacuum region between photocathode and the detector. A conductor disposed on or adjacent to a sidewall of the vacuum envelope reduces the effect of electrical charges on the inside wall of the vacuum envelope on the trajectories of the electrons. An ion deflector electrode is disposed adjacent to the photodiode anode and extends photocathode operational life and improves noise factor.

Abstract: The electron multiplying device according to this invention comprises an electron multiplying unit including dynodes arranged in a plurality of stages. The electron multiplying unit has an incidence opening for an energy beam to be multiplied to enter through, and has the proximal end secured to a base. There is provided a casing for housing the electron multiplying unit. The forward edge of the casing is secured to the base, and a space defined by the base and the casing houses the electron multiplying unit. The casing has an entrance window formed at a position opposed to the incidence opening. Energy beams enter the electron multiplying unit through the entrance window, but the electron multiplying unit itself is housed in the casing to be protected from surrounding air flow and unnecessary energy beams not to be measured.

Abstract: A photomultiplier assembly for use in gamma cameras, for example, includes an array of head-on type photomultipliers disposed in parallel relation to one another. The array of photomultipliers has a plurality of dead spaces, in which reflectors are respectively disposed. The reflector can reflect light which has entered the corresponding dead space to an upper portion of a side wall of aproximate photomultiplier. A side photocathode surface is formed on an inside surface of the upper portion of the side wall of the photomultiplier. Therefore, the light which has entered the dead space is reflected by the reflector and impinges on the side photocathode surface to be converted into photoelectrons.
