ELECTRON GUN FOR O-TYPE DEVICE

摘要

FIELD: microwave devices such as traveling-wave tubes or klystrons. SUBSTANCE: electron gun used for O-type traveling-wave tubes or klystrons with low-voltage modulation of electron current has cathode, focusing electrode, grid structure disposed near cathode, and anodes. Cross-section of jumpers of at least one grid is shaped as isosceles triangle whose vortex faces anode. EFFECT: facilitated current passage due to reduced electron-current distortions of grid structure. 2 cl 9 dwg
