Problems solved by technology

As the power of traveling wave tubes increases, simply adding a modulation voltage to the anode or focusing electrode is far from being able to satisfy the control function of large currents.

Abstract

The invention relates to an electronic control aperture plate welding tool and belongs to the technical field of vacuum microwave devices. The welding tool comprises a base, an expansion welding pressing block, a pressing plate, a supporting rack and a control aperture plate. A central hole is formed in the base from the axis to the outside. The supporting rack is arranged in the central hole. A groove used for containing the control aperture plate is formed in the bottom wall of the expansion welding pressing block. The expansion welding pressing block is fixedly arranged on the control aperture plate. The control aperture plate is fixedly arranged on the supporting rack. The pressing plate is fixedly arranged on the expansion welding pressing block. The invention further provides a welding method of the electronic control aperture plate welding tool. For assembling and welding of the control aperture plate in a microwave traveling-wave tube grid-controlled electron gun, the effect that atoms diffuse and infiltrate mutually sufficiently on the contact surfaces between components in the high-temperature vacuum is achieved, and welding between the components is more stable and firmer.

Description

technical field [0001] The invention relates to an electronic control grid welding tool and a welding method, in particular to the assembly and welding of a control grid in a microwave traveling wave tube grid control electron gun, and belongs to the technical field of vacuum microwave devices. Background technique [0002] High-power traveling wave tube is the core device of radar and electronic countermeasure system in modern weapon assembly, and is known as the "heart" of electronic system. As the power of the traveling wave tube increases, simply adding a modulation voltage to the anode or focusing electrode is far from being able to satisfy the control function of large current. Therefore, a control grid electrode closer to the cathode than the anode or focusing electrode is set in the electron gun to control the cathode emission current, so as to achieve the purpose of controlling a large injection current with a small power (or voltage). In the case of pulse work, si...
