摘要： A broadband transverse field interaction continuous beam amplifier device mprised of an elongated continuous cathode modulating grid structure, an elongated continuous demodulating grid-collector structure, first or input waveguide transmission line means including the modulating grid for propagating an input RF wave transversely to an electron beam traveling from the cathode-grid structure to the output-collector structure where the electrons are bunched or modulated by the process of transverse wave interaction, and second or output waveguide transmission line means including the demodulating grid for propagating an induced amplified RF output wave resulting from prebunched electrons traversing the demodulator grid. Both input and output transmission line means include slow wave structures which are implemented in the grid structures.

摘要： A transverse field interaction multi-beam amplifier device comprising a structure having, for example, a plurality of discrete cathodes cylindrically located in succession along a central axis of RF propagation. In registration with the cathodes are a respective number of annular collectors located within an outer cylinder which also acts as the structure housing. Intermediate the cathodes and collectors are two additional coaxial cylinders, one having a relatively smaller diameter than the other, with the smaller diameter cylinder including respective number of discrete grids, while the larger cylinder comprises a structure preferably having a rippled or undulating slow wave wall surface and a respective number of annular slots formed therein. The cathodes emit radial beams of electrons which pass through and are bunched by the grids and then accelerated by the slots to the collectors while interacting with and being modulated by an input RF beam propagating along the central axis of the coaxial structure between a first pair of cylinder walls including the grids and cathodes and inducing an output beam in a second pair of cylinder walls including the slots in the slow wave wall surface and the grids.
