Abstract: A millimeter-wave extended interaction device, including: a device body; resonant cavities; electron beam tunnels; an output waveguide; and a coupling hole. The device body includes a shell and a core, and an annular coupling channel is disposed between the shell and the core. The resonant cavities are a set of ring-shaped cavities with a radial height of 2 /5 λ, to 3/5 λ, parallel and equally spaced around an axis of the core. The electron beam tunnels are arranged at equal radian intervals and parallel to the axis of the core. The output waveguide is disposed in the middle of the shell and communicates with the annular coupling channel through a coupling hole. The core and the inner surface of the shell are sealed and fixed, and the output waveguide and the shell are sealed and fixed.

Abstract: A device for measuring the emission angle of a particle beam. The device includes a shell, a data acquisition board, a data collector, a data processor and a data synchronization display. The shell is hollow tubular. The data acquisition board is fixed to the front end of the shell. The data collector and the data processor are fixed together and fixed to the back end of the shell. The data collected by the data acquisition board is transmitted to the data collector through the data line collector, and the data processor transmits the processed data to the data synchronization display. The ion accelerator to be measured is located in front of the data acquisition board, and the particles emitted by the ion accelerator bombard the front of the data acquisition board. The data acquisition board comprises an insulating ring, an array insulating board and a pressure sensor.

Abstract: A rectangular magnetron tube core including: an anode component having two openings respectively formed in two end portions thereof; a cathode component disposed on the center axis of an anode barrel; an input component and an output component respectively disposed on the two openings formed outside the two end portions of the anode barrel. The anode component includes: the anode barrel, a plurality of anode vanes, two strapping rings, an A-side pole shoe and a K-side pole shoe. The anode vanes are uniformly disposed on the inner side wall of the anode barrel. The tips of the anode vanes leave a tubular space at the center axis of the anode barrel, and the two strapping rings are both ring-structure erected on both sides of the anode vanes. The structure of the A-side pole shoe is completely symmetrical with that of the K-side pole shoe.
