O-TYPE DEVICE Russian patent published in 1994 - IPC

Abstract RU 2019879 C1

FIELD: electronic tubes. SUBSTANCE: SHF O-type device has electron gun, electrodynamic system, magneto-focusing system with pole pieces, collector system, unit of conversion of magnetic leakage field located coaxially to electron beam over section between collector and collector pole piece and manufactured in the form of two profiled cone-cylindrical axial screens arranged in succession one after another along axis of device and separated from each other, from collector and from collector pole piece with the use of nonmagnetic bushings. Vertexes of conical parts of profiled screens are directed towards collector pole piece. Geometrical dimensions of screens and nonmagnetic bushings are selected in agreements with certain relations. EFFECT: provision for required degree of focusing of electron beams with different parameters. 2 cl, 2 dwg
