Abstract: An electron gun cathode (104) is column shaped, and emits electrons by being heated. A holder (103), which covers the bottom and sides of the electron gun cathode, has electrical conductivity and holds the electron gun cathode, and is composed of a material that does not easily react with the electron gun cathode when in a heated state, is provided. The tip of the electron gun cathode (104) protrudes from the holder (103) so as to be exposed, and electrons are emitted from the tip toward the front by applying an electric field to the tip.

Abstract: An electron gun is provided, in which a capacitance between a cathode and other electrodes, especially a control electrode is reduced largely without substantially changing a structure for supporting the cathode with an insulator. The cathode of this electron gun is disposed inside of the cylindrical metal shell. The cathode and the cylindrical metal shell are connected by three metal tabs. The cylindrical metal shell fits into a hole formed in the center portion of the insulator, and a metal outer frame is attached to the periphery of the insulator. The metal outer frame is welded to the inner surface of a cathode metal support. There is a control electrode facing the electron emitting surface of the cathode at a predetermined distance. Plural electrodes including an accelerating electrode are disposed in turn beyond the control electrode. Peripheries of the cathode metal support, control electrode, an accelerating electrode and other electrodes are embedded into sides of a pair of supporting rods that extend axially, so that the electrodes are fixed with a predetermined space between the electrodes.

Abstract: A low-power cathode can be obtained by arranging it on a substrate (1), preferably of silicon, which is entirely or partly removed at the location of the emissive structure (11) by means of, for example, anisotropic etching. Because of its low power, the cathode is particularly suitable for multi-beam applications.

Abstract: Performance of fast warm up cathodes can be improved by providing a black heat radiating surface on the interior of the cathode cap. A particular material can be nichrome which is a nickel chromium alloy. The cathode cap material can be selected from any of the known cathode nickel alloys. A preferred method for accomplishing the result includes the steps of cladding a selected nickel alloy with the nichrome material and then forming the substantially cup shaped cap with the clad material on the interior thereof. The formed cathode cap is then fired for about 10 minutes or longer in wet dissociated ammonia at a temperature of about 900.degree. to 1300.degree.C to oxidize the available chromium on the surface of the nichrome. This produces an even dark surface thereon which has much higher heat radiating capabilities than the silver looking nickel cathode alloy.
