The invention discloses an S-waveband high-peak power klystron two-arm output device. The device comprises an output cavity and a two-arm waveguide device, wherein the two-arm waveguide device comprises two same single-arm waveguide devices; the two same single-arm waveguide devices are symmetrically connected with the output cavity, respectively; each single-arm waveguide device comprises a first bent waveguide, a straight waveguide, a second waveguide assembly, an output window assembly and a second straight waveguide assembly, all of which are orderly connected from bottom to top. The S-waveband high-peak power klystron two-arm output device is simple and easy to implement; compared with other traditional single-arm output cavity, the two-arm output device is higher in working reliability and stability within the working frequency band under the condition of the same power level output.

Description

technical field [0001] The invention relates to the technical field of electric vacuum devices, in particular to an S-band high peak power klystron double-arm output device in microwave electric vacuum devices. Background technique [0002] Among the many microwave electric vacuum devices, the klystron is one of them. The klystron is an electronic device that uses the movement of charged particles between electrodes to realize the oscillation or amplification of microwave signals in a vacuum state. Ordinary klystrons have the characteristics of high power, high gain and high efficiency. As the peak power of the klystron increases, the high-frequency electric field of the gap in the output resonant cavity also increases, and the high-frequency breakdown of the gap becomes a limitation The main factor for klystron peak power. In high peak power klystrons, the breakdown and damage of the output window are important factors affecting the reliability, stability and life of the k...

Problems solved by technology

Experiments have shown that there are three types of damage to high-power output windows: 1) Dielectric faults lead to perforation of ceramic windows, which cause ignition when the electric field strength on the surface of the window exceeds the dielectric strength of the material; 2) Overheating of the window causes the window to burst , due to the temperature difference between different parts caused by the heat loss of the window, thermal stress is generated. When the thermal stress is greater than the bending strength of the ceramic material, the window will burst; 3) The thermal stress at the welding point of the window and the window frame causes the output window leak
