MULTIRANGE O-TYPE DEVICE Russian patent published in 2007 - IPC H01J25/00 H01J25/10 H01J25/34 

FIELD: multirange microwave devices for radar stations.

SUBSTANCE: proposed multirange O-type device used for radar stations to replace separate devices for each range thereby simplifying station design and reducing its cost is assembled of electrodynamic systems disposed along electron beam and isolated from each other by conducting disks with drift tubes. Each electrodynamic system is provided with energy input and output. Operating-range wavelength of electrodynamic system rises in direction of electron beam motion and ratio of electrodynamic system diameter to this wave reduces in same direction. Transit-time channel diameter remains constant or increases from system to system in direction of electron beam motion.

EFFECT: enhanced self-excitation resistance, reduced probability of current lowering, minimized size and mass.
