摘要： A high impedance circuit has radially disposed first vanes and radially disposed second vanes interdigitating between the first vanes. The first vanes and the second vanes are each interconnected by a first toroidal strap and a second toroidal strap, respectively. The first strap and the second strap are dipsosed co-axially on opposite sides of the vane structure. The vanes and straps are dimensioned so that the circuit has a single cavity impedance commensurate with a predetermined interaction impedance for the oscillator which is sufficient to sustain oscillation for a preselected injection locking bandwidth of the oscillator.

摘要： An uncoated radiative heating filament wire is electrically and thermally isolated from the cathode of a high power magnetron. The filament wire helically surrounds the cathode support rod and is suspended above the support rod surface by ceramic members. A reflective shell envelops the helical filament wire and cathode support rod. The shell reflects radiated heat from the filament wire evenly upon the cathode support rod.

摘要： An anode structure of the present invention provides radially disposed first vanes and radially disposed second vanes interdigitating with the first vanes. The first vanes and the second vanes are each interconnected by a first strap and a second strap, respectively. The first strap and the second strap are disposed coaxially on the same side of the vane structure and are generally rectangular in cross-section, having substantially parallel facing surfaces. Each of the vanes is generally T-shaped, with a relatively wide high capacitive first portion and a relatively narrow high inductive second portion. The first portion is disposed proximate to an axis of the cavity with the second portion extending radially outward therefrom. The anode structure has at least thirty anode vanes.

摘要： A magnetron transition apparatus is provided which permits transmission of a microwave RF signal between a magnetron and an output waveguide. The transition apparatus is connected to the magnetron and receives the RF signal from the magnetron, while maintaining a substantially vacuum environment therein. The transition apparatus further comprises an RF interface between the substantially vacuum environment and a non-vacuum environment within the output waveguide. The microwave RF signal from the magnetron is transmitted through the transition apparatus into the output waveguide. The transition structure comprises an adapter having a first portion of generally circular cross-section and a second portion of generally rectangular cross-section. A conductive loop electrically connected to an anode structure of the magnetron is disposed within the first portion and inductively couples the RF signal from the magnetron into the transition apparatus. The RF interface further comprises an RF transparent window connected between the second portion of the adapter and the output waveguide. The second portion of the adapter has a cross-section consistent with that of the output waveguide.

摘要： A tuning assembly is disclosed for selectively oscillating the frequency of an electromagnetic field within a hermetically sealed device, which device includes a rigid, hermetically sealed housing, apparatus for generating the electromagnetic field therewithin, and elements for defining a cavity within the housing for establishing the frequency of the electromagnetic field. The tuning assembly includes electrically conductive members mounted for linear movement within the cavity to selectively vary the volume of the cavity to oscillate the established frequency. Elements disposed within the rigid housing are provided for mounting the electrically conductive members, and are adapted for oscillatory movement at a pre-determined mechanical resonant frequency to move the electrically conductive members in the described linear manner. Finally, a power source is provided exterior to the rigid housing and is magnetically coupled to the mounting elements for exciting the mounting elements.

摘要： A tuning assembly (42) is disclosed for selectively oscillating the frequency of an electromagnetic field within a hermetically sealed pulsed magnetron (12), comprising a rigid, hermetically sealed housing (14), apparatus for generating the electromagnetic field therewithin (32, 34, and 36), and elements for defining a cavity (30) within the housing for establishing the frequency of the electromagnetic field. The tuning assembly (42) includes electrically conductive members (54) mounted for linear movement within the cavity (30) to oscillate the established frequency. Elements (52) disposed within the rigid housing (14) are provided for mounting the electrically conductive members (54), and are adapted for oscillatory movement at a predetermined mechanical resonant frequency to move the electrically conductive members (54) linearly. The tuning assembly (42) incorporates a highly efficient electron-emitter (cathode) assembly (24, 102) arranged in the form of a tightly-wound, helical member (102), the cathode assembly (24, 102) being directly heated and composed of porous tungsten impregnated by a mixture of barium and calcium aluminates. The helical member (102) is machined and has a rectangular cross-section, so as to present a substantially cylindrical emitting surface having a maximum emitting area. Finally, a power source (108) is provided exterior to the rigid housing (14) and is magnetically coupled to the mounting elements (44) for exciting them.
