MAGNETRON Russian patent published in 2014 - IPC H01J25/50 

FIELD: electricity.

SUBSTANCE: magnetron has the first set of blades 20, which are connected by outputs 52 with a coaxial output device 51 of communication, and the second set of blades 19, which (in one version) alternate with blades of the first set and are not connected with the output communication device. Blades of each set are retained, for instance, by bracing rings, which may be distributed along the length of the anode under one potential relative to each other, and polarity of one set of blades is opposite to polarity of the other set. An additional capacitance link is introduced by means of axial extenders 19a at the ends of the set of blades 19, which are not connected with the output communication device, and by selecting the size the cathode is substantially disconnected from the output communication device due to the opposite polarity of two sets of blades.

EFFECT: reduced losses of power.
