    摘要： A rising-sun magnetron tube is disclosed employing a composite tuning ring structure axially translatable in an end space region adjacent the open ends of the anode resonators. The composite tuning ring includes a pair of conductive rings separated by a ceramic insulator. In a preferred embodiment the conductive ring facing the anode circuit is disposed in axial registration with the back wall of the small anode resonators and has a radial width less than that of the other ring. The resultant tuner has increased tuning range and a more linear tuning rate to facilitate temperature compensation.

    摘要： A tunable resonant cavity device is provided which contains a pair of metal bellows connected in tandem with one end of each bellows anchored to fixed spaced locations within the body of the device. One fixed end of one bellows is sealed closed, whereas the other fixed end contains an opening through which one mechanical element in the tuning mechanism extends. The bellows are joined in tandem by a moveable member to which an end of each bellows is sealed. The moveable member contains a passage which extends therethrough to permit equalization of pressure on each side thereof and between the bellows. Another mechanical element of the tuning mechanism is connected to this moveable member along its periphery on the outside of the bellows. The mechanical movement of an external tuner mechanism is transmitted through a coupling to one of the aforementioned tuning elements, the tandem bellows to the other mechanical element and in so doing causes one of the bellows to be compressed and the other to expand although the total volume enclosed by the tandem connected bellows is substantially constant. The other mechanical element is coupled to the tuning element located in the sealed evacuated resonant cavity which is sealed closed by the tandem bellows structure. Inasmuch as the pressure on each side of the moveable member is equal, the vacuum force due to differential pressure between the outside and the inside of the evacuated cavity is canceled.

    摘要： An air cooled coaxial magnetron is disclosed. The magnetron includes a coaxial arrangement of anode and cathode electrodes to define a magnetron interaction region in the space therebetween. The anode electrode includes an anode wave circuit and a coaxial circular cavity resonator with a cylindrical common wall disposed therebetween, such wall having an array of axially directed coupling slots communicating between the circular cavity and the wave circuit for controlling the frequency of the tube. An inner heat shunt is affixed to one end of the cylindrical anode wall and extends axially of the tube for connection to a radially directed heat shunt and to an array of radially directed cooling fins. An outer axially directed heat shunt interconnects the outer ends of the cooling fins to the radially directed heat shunt to enhance thermal conduction of heat from the anode wall to the cooling fins for improved cooling efficiency of the tube.
