ABSTRACT:
A crossed-field amplifier (CFA) includes a cylindrical cathode having an emitting surface coaxially disposed within an annular anode structure. The cathode has at least one circumferential groove disposed in the emitting surface. The grooves are relatively deep in comparison with their width. The grooves provide a phase smoothing of the rotating electron cloud spokes operative during crossed-field interaction. CFA noise is reduced by removal of the out-of-phase electrons. Due to their deeply cycloiding paths, these out-of-phase electrons become trapped in the grooves within a region generally shielded from the electric field of the CFA.
