TRAVELING-WAVE TUBE Russian patent published in 2005 - IPC

FIELD: electronic engineering, in particular, traveling-wave tubes.

SUBSTANCE: the traveling-wave tube has an electron gun, inhibiting system of the coupled resonators type, electrostatic periodic focusing system made in the form of electrodes fastened on holders and placed in the cavities of the resonators, and a collector. A long-focus magnetic lens is installed between the inhibiting system and the collector. A vacuum envelope is provided around the inhibiting system, which has supporting rods and insulators, the supporting rods (1-3) are installed outside the resonators in parallel with the axis of the inhibiting system and electrically coupled to the cathode of the electron gun. The insulators are made in the form of bushes fastened on the outside walls of the resonators and rigidly connected to the supporting rods. The electrode holders are connected to the supporting rods and insulated with the id of a vacuum gap from the walls of the resonators.

EFFECT: produced a high-power traveling-wave tube for use in the output stages of transmitting devices.
