Abstract: An active electronically steered cathode (AESC) applies one or more electromagnetic modes to an input cavity, similar to that used in an inductive output tube. The structure and superposition of these modes creates local electric field maxima, causing the electron emission site or sites to move or be distributed across the surface of the cathode. Changing the amplitude, phase, or frequency of the modes provides time-variable control of the electric field profile, thereby generating electronically steered electron beams. One embodiment employs a pair of orthogonal TM modes driven out of phase, causing the electric field maximum to rotate around an annular cathode, producing a helical beam. Slots in the control grid may be used to segment the helical beam into discrete bunches to provide additional density modulation.

Abstract: A grid component for use with a vacuum electron device (VED), such as an inductive output tube (IOT), includes a skirt that adds structural support and aids in alignment. The grid component has a dome in which a grid pattern is formed and includes an annular, concentric flange surrounding the dome. The skirt is formed concentrically around the flange. Alignment orifices may be provided in the flange for passage of alignment pins in the assembled product. The grid, flange, and skirt are a unitary component and are formed by a chemical vapor deposition (CVD) or similar process, in which a mandrel is used to provide a deposition surface. The mandrel is placed in a furnace, and a high-temperature CVD process is used to break down a hydrocarbon gas to thereby deposit a pyrolytic graphite coating onto the mandrel. The mandrel may include a skirt template to provide the characteristic skirt.

Abstract: An electron gun for generating an electron beam is provided, which includes a secondary emitter. The secondary emitter includes a non-contaminating negative-electron-affinity (NEA) material and emitting surface. The gun includes an accelerating region which accelerates the secondaries from the emitting surface. The secondaries are emitted in response to a primary beam generated external to the accelerating region. The accelerating region may include a superconducting radio frequency (RF) cavity, and the gun may be operated in a continuous wave (CW) mode. The secondary emitter includes hydrogenated diamond. A uniform electrically conductive layer is superposed on the emitter to replenish the extracted current, preventing charging of the emitter. An encapsulated secondary emission enhanced cathode device, useful in a superconducting RF cavity, includes a housing for maintaining vacuum, a cathode, e.g., a photocathode, and the non-contaminating NEA secondary emitter with the uniform electrically conductive layer superposed thereon.

Abstract: An electron beam tube device has a magnetic frame with the top part being pivotable so as to pivot from a closed position in which the top part, including an electromagnetic coil covers the electron beam tube to an open position in which the electron beam tube is uncovered. This allows electron beam tubes with either large parts or integral parts such as output feeders to be removed from the magnetic frame without complete removal of the top plate.

Abstract: An amplifier including an electronic tube with an axial electron beam, provided with a cathode and at least two collectors, and at least two sources of DC voltage. Each collector is connected to a DC voltage source having a potential difference such that, the further the collector is from the cathode, the lower the potential difference between this collector and the cathode. The DC voltage sources are connected together at a common point situated at the collector whose potential difference with the cathode is the lower but not zero.
