Abstract: A multibeam electron tube with several approximately parallel electron beams passing through a body. Among the beams, at least some define an interbeam volume, each beam defining the interbeam volume being subjected to a perturbing azimuthal magnetic field induced by all the other beams. The tube includes an element allowing, in at least one conducting element located in the interbeam volume, flow of a reverse current in the opposite direction to that of the current of the beams, this reverse current generating, in the beams defining the interbeam space, a magnetic correction field whose purpose is to oppose the perturbing magnetic field. Exemplary embodiments of the present invention especially apply to the multibeam klystrons or traveling wave tubes.

Abstract: Improved electric field (steered-electron electric-field, or SEEF) sensors and methods of manufacturing the same are provided. The SEEF sensors described herein may have increased sensitivity to low-frequency electric fields while being smaller than previously known sensors, and may allow for low-power electric field detection. The invention described herein allows for sensitive, long-term electric field monitoring for applications ranging from personnel detection to underground facility monitoring, as well as extraordinarily small vector sensing (full Poynting vector) for compact direction-finding of emitters of interest. Exemplary electric field sensors may accurately sense, measure, characterize and/or transmit electric field data over a wide frequency range. Importantly, such sensing, measuring, and/or characterizing do not require any physical or resistive contact between the sensor and a source of an electric field.

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.
