TRAVELLING WAVE TUBE Russian patent published in 2013 - IPC H01J25/00 

FIELD: electricity.

SUBSTANCE: travelling wave tube (TWT) of ultrahigh-frequency range of wave lengths comprises an electron gun, a moderating system of "opposite pins" type, comprising connected cells, dielectric sealing partitions that separate the moderating system from microwave tracks, a focusing system in the form of a chain of permanent magnets and a collector. Between flight tubes of the input and output resonators of the moderating system and inner conductors of coaxial tracks there are capacitance gaps, and input and output resonators have a diameter that is more than the diameter of the moderating system.

EFFECT: reduced power consumption of a TWT and increased working frequency band.
