RELATIVISTIC MAGNETRON WITH EXTERNAL CHANNELS OF RESONATORS COMMUNICATION Russian patent published in 2008 - IPC H01J25/50 

FIELD: electricity.

SUBSTANCE: invention is related to the field of relativistic high-frequency electronics and may be used for generation of intense microwave radiation. Relativistic magnetron with external channels of resonators communication has explosion-emission cathode (3), anode unit (1) with N resonators, cylindrical drift tunnel, magnet system (4) in the form of Helmholtz pair and wave-conductor power outlets (2) with number of n=2m, ... N, where m=1, 2, ... N/2 - integer number. Wave-conductor power outlets (2) of oppositely installed resonators are connected by means of m wave-conductor channels (5, 8) of rectangular section with length multiple of (2q+1)λ/2 for relativistic magnetron with number of resonators that satisfy the following condition: N/2 - even number, with length multiple of λq for relativistic magnetron that meets the following requirement: N/2- odd number, where q - positive integer number. In wave-conductor channels (5, 8) communication slots are provided with length) λ/2 for microwave emission outlet. Communication slots (6, 9) with number 2k are installed on wide wall of wave-conductor channel at the distance of λ/2 between each other, and one communication slot (7, 10) is installed on narrow wall of wave-conductor channel. For relativistic magnetron with number of resonators that satisfy the following condition: N/2 - even number, axes of communication slots (6) on wide wall of wave-conductor channel (5) are installed at the distance of pλ/2+λ/4 from channel axis alternately on different sides from middle line of wall, and communication slot (7) on narrow wall of wave-conductor channel (5) is installed on channel axis. For relativistic magnetron with number of resonators that meet the following requirement: N/2 - odd number, axes of communication slots (9) on wide wall of wave-conductor channel (8) are located at the distance of pλ/2 from axis of channel alternately on different sides from middle line of wall, and communication slot (10) on narrow wall of wave-conductor channel (8) is installed at the distance of pλ/4 from channel axis (p=0, ±1, ±2, ... ±k - integer number, λ - length of radiation wave of relativistic magnetron in wave-conductor channel).

EFFECT: creation of relativistic magnetron with external channels of resonators communication, which may be used for generation of intense microwave radiation.
