Abstract: Vacuum electron devices (VEDs) are produced having a plurality of two-dimensional layers of various materials that are bonded together to form one or more VEDs simultaneously. The two-dimensional material layers are machined to include features needed for device operation so that when assembled and bonded into a three-dimensional structure, three-dimensional features are formed. The two-dimensional layers are bonded together using brazing, diffusion bonding, assisted diffusion bonding, solid state bonding, cold welding, ultrasonic welding, and the like. The manufacturing process enables incorporation of metallic, magnetic, and ceramic materials required for VED fabrication while maintaining required positional accuracy and multiple devices per batch capability. The VEDs so produced include a combination of magnetic and electrostatic lenses for electron beam control.

Abstract: A magnetron has an anode cylinder, a plurality of vanes arranged radially within the anode cylinder, a magnetic piece disposed at an open end section of the anode cylinder, an anode vacuum container including a metal container disposed to cover an upper surface of the magnetic piece, a cathode disposed along a central axis of the vacuum container, and an antenna externally discharging microwaves. The magnetic piece and the metal container are placed, in that order, on a shelf formed inwardly on a thin end section projecting from the open end section of the anode cylinder. When tightly welding the thin end section, a predetermined number of projections, projecting inwardly from the thin end section of the anode cylinder, loosely secure an outer perimeter bend of the metal container. The metal container is then accurately tightly welded to the anode cylinder without the metal container shifting off-center.

Abstract: The inner surface of a barrel for a traveling wave tube is formed with a set of tracks extending parallel to the longitudinal axis of the barrel. The rods supporting the traveling wave tube circuit assembly are supported in the tracks. The tracks are formed by forcing a tool having track-forming elements through the barrel, or a succession of ever-larger tools may be used to first form and then gradually enlarge the tracks.

Abstract: A coupled cavity traveling tube employs a number of adjacent stacked annular magnetic coils (52a-52l) of insulated copper tape mounted on a housing (40) that contains an electron beam path (22) surrounded by a coupled cavity circuit (42,44). An electron beam that is focused by the annular magnetic coils is projected by an electron gun (10) at one end of the traveling wave tube to a collector (26) at the other end of the electron beam path. RF input and output ports (48,50) are coupled to opposite ends of the coupled cavity circuit, with the entire assembly mounted in an outermost device housing (12,28,36) that is sealed to and around the externally projecting RF input and output ports by a pair of sealing rings (60,62) that circumscribe coils (52b,52c,52l) at opposite ends of the traveling wave tube. Hot melt plastic (58a-58i) is injected into spaces between adjacent ones of the annular coils to firmly position the stack of coils against shock and vibration. Expandable support elements (80,82) are positioned in intercoil spaces that are inaccessible because of the sealing rings. The expandable support elements respond to flowing cooling oil by expanding to resiliently urge the coils that they contact in axial directions, thereby exerting axially directed resilient compressive forces on the entire stack of coils to stabilize their position and resist shock and vibration to which the traveling wave tube may be subjected.

Abstract: A method for the manufacture of a helix-coupled vane line consists in cutting out, in a part comprising at least one channel, successive slots through the channel that extend beyond the channel so as to obtain portions of turns each fixedly joined to a vane; cutting out, in another part, a succession of fingers that are all fixedly joined to each other; connecting the turn portions to the fingers so that one end of a turn portion is connected to one end of a first finger and the other end of the turn portion is connected to the base of a second finger adjacent to the first finger; and separating the fingers from one another at their bases. Application of helix-coupled vane lines. Is most notably for crossed-field amplifiers.
