Abstract: A cathode (5) for emitting photoelectrons or secondary electrons comprises a nickel electrode substrate (5c) with an aluminum layer (5b) deposited on it; an intermediate layer (5a) consisting of carbon nanotubes formed on the aluminum layer; and an alkaline metal layer (5d) formed on the intermediate layer (5a) and composed, for example, of particles of an alkali antimony compound that either emits photoelectrons in response to incident light or emits secondary electrons in response to incident electrons. The decrease in defect density of the particles reduces the probability of recombination of electron and hole remarkably, thus increasing quantum efficiency.

Abstract: Cathodoluminescent field emission display devices feature phosphor biasing, amplification material layers for secondary electron emissions, oxide secondary emission enhancement layers, and ion barrier layers of silicon nitride, to provide high-efficiency, high-brightness field emission displays with improved operating characteristics and durability. The amplification materials include copper-barium, copper-beryllium, gold-barium, gold-calcium, silver-magnesium and tungsten-barium-gold, and other high amplification factor materials fashioned to produce high-level secondary electron emissions within a field emission display device. For enhanced secondary electron emissions, an amplification material layer can be coated with a near mono-molecular film consisting essentially of an oxide of barium, beryllium, calcium, magnesium or strontium. Use of a high amplification factor film as a phosphor biasing electrode, and variability of the phosphor biasing potential to achieve brightness or gray scale control are further described in the disclosure.

Abstract: A photomultiplier is constituted by a photocathode and an electron multiplier having a typical structure in which a dynode unit having a plurality of dynode plates stacked in an incident direction of photoelectrons, an anode plate, and an inverting dynode plate are sequentially stacked. Through holes for injecting a metal vapor are formed in the inverting dynode plate to form secondary electron emitting layers on the surfaces of dynodes supported by the dynode plates, and the photocathode. With this structure, the secondary electron emitting layers are uniformly formed on the surfaces of the dynodes. Therefore, variations in output signals obtained from anodes can be reduced regardless of the positions of the photocathode.

Abstract: Before being introduced within the intensifier, the grid which is nearest the anode is coated with a layer of electrically conductive material having the property of oxidizing alkali metals. This has the effect of elininating any parasitic illumination of the viewing screen caused by alkali metals unintentionally deposited on the grid at the time of formation of the photocathode.

Abstract: An improved microchannel plate is shown fabricated from tubes formed from at least two types of cladding glass and a core glass, including a first cladding of partial acid resistant glass and a second, super cladding of high acid resistant glass. The first cladding may surround a hollow core that forms a passage or it may surround a core of low acid resistant glass which is removed by an acid bath to form the passage. The second cladding surrounds the first, while the opening of the passage surrounded by the first cladding is tapered by an acid etch that does not affect the second cladding. Thus, the ratio of the open area of the passages to their end surface area is controlled only by the removal of the first cladding.

Abstract: The invention includes an electron tube such as an image intensifier which utilizes a channel-type electron multiplier. The multipler is made of a perforated glass plate made in a manner such that secondary emission may be produced at the interior surfaces of the holes through the plate. Primary electrons are introduced to the holes at one end and a much larger emission emanates from the other end. Conductive layers on each side of the plate have holes in registration with the plate holes. The conductive layers are maintained at potentials to accelerate electron flow through the holes. In accordance with the present invention, a third conductive layer is provided at the output side. When the third conductive layer is maintained negative, resolution is improved.
