Abstract: An improved electron discharge device comprises an evacuated envelope having therein a photoemissive cathode for providing photoelectrons in response to radiation incident thereon, an electron multiplier, including a primary dynode spaced from the cathode, and a focusing assembly disposed between the cathode and the multiplier. A thermionic electron control plate is disposed between the focusing assembly and the multiplier to prevent thermionic electrons from the focusing assembly from impinging on the primary dynode, while permitting the passage of photoelectrons to the primary dynode. The control plate overlies the primary dynode and is contiguous therewith.

Abstract: A multi-channel photomultiplier tube in which light radiation from distinct sources passes through an entrance window to a photo-cathode, the window being divided into parts so that light from a source passes through a respective part to an associated part of the photo-cathode, the division of the window into parts constraining the light from incidence upon other parts of the photo-cathode.

Abstract: A dielectric body which is permeable to electromagnetic wave energy of a material selected from the group consisting of alumina and beryllia ceramics is provided with a coating of a semiconducting oxide to substantially suppress electron multipactoring. The exemplary materials include semiconducting oxides of silicon and transition metals including copper, cobalt, chromium, iron, manganese and nickel. Thicknesses averaging 1,000 Angstrom units have resulted in substantial increases in the power handling ability of electromagnetic devices employing such dielectric bodies.

Abstract: A photodetector system including a photocell of the type having a photosensitive coating on the internal surface of a plane transparent wall forming part of the envelope of the cell. At least one prism whose principal section has the form of a trapezoid is attached to the wall so that the shorter one of the two parallel sides of the prism is in contact with the exterior surface of the wall in front of a central portion of the coating. The lengths of the sides and the angles of the principal section of the prism are so chosen that a bundle of light entering the longer one of the parallel sides at right angles to that side, is in part reflected by a first one of the nonparallel sides towards the other one of the nonparallel sides and reflected towards the wall by the last-mentioned side, while another part of the light bundle is reflected by the first one of the nonparallel sides directly towards the wall, both parts entering the wall under an angle of about 45*.

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: Ion detectors of the type used in scientific instrumentation, such as mass spectrometers. More particularly, a self-contained particle detector includes an enclosure formed in part by a transmission mode secondary electron emissive element, the enclosure defining an internal environment and an external environment, wherein the transmission mode secondary electron emissive element has an externally facing surface and an internally facing surface and is configured such that impact of a particle on the externally facing surface causes emission of one or more secondary electrons from the internally facing surface.
