MULTIBEAM MICROWAVE DEVICE OF O-TYPE Russian patent published in 2014 - IPC H01J25/10 

FIELD: electricity.

SUBSTANCE: multibeam microwave device of O-type comprises an electron gun, an energy input and output, a collector and an electrodynamic system, comprising input, output and intermediate active resonators, the first output passive resonator, electromagnetically connected to the output active resonator. The input, output and intermediate active resonators are made in the form of sections of wave guides with a working type of oscillations H₃₀₁, in each input, output and intermediate active resonator for passage of electronic beams there are three groups of individual drift tubes. Drift tubes of each group have axial-symmetrical placement in the form of at least one circular row, and the diameter of the circumference D, which limits the external circular row of drift tubes of each group is selected on the basis of the condition D=(0.32÷0.42)λ, where λ - wave length corresponding to the central frequency of the working band of the device.

EFFECT: higher pulse and average output capacity in wide band of frequencies with sufficient electric strength, higher efficiency factor.
