Stacked frame electron gun of space traveling wave tube

Abstract

The invention discloses a stacked frame electron gun of a space traveling wave tube. The stacked frame electron gun comprises a gun core, an insulating porcelain cylinder, a bunching pole, a bunchingpole sealing ring, a circular ring consisting of two pieces of semicircular corrugated porcelain, a first anode sealing ring, a corrugated porcelain ring with a hole, a second anode sealing ring, a corrugated porcelain ring, a supporting seat, a metal shell, five lead insulating porcelain columns, a first anode and a second anode. The bunching pole sealing ring, the circular ring, the first anodesealing ring, the corrugated porcelain ring with the hole, the second anode sealing ring, the corrugated porcelain ring and the supporting seat are stacked to form a supporting and insulating structure. Good structural reliability is formed while the insulation distance of each electrode electrified assembly is ensured, and the mechanical resistance is excellent.

Description

technical field [0001] The invention belongs to the traveling wave tube technology, in particular to a space traveling wave tube stacked frame electron gun. Background technique [0002] In the design of space traveling wave tube, lightweight, miniaturization and high reliability design are the key research contents. As one of the core components of the space traveling wave tube, the electron gun's volume, weight and reliability greatly affect the relevant indicators of the whole tube. [0003] The traditional electron gun structure is a laminated electron gun structure composed of a corrugated ceramic ring and a sealing ring. Laminated electron gun structure, the sealing ring and the metal sealing ring are overlapped and welded to form an airtight, insulating and electrode supporting structure. The lead wire of the electron gun is welded on the sealing ring. The whole electron gun is potted with silicone rubber. The silicone rubber surrounds the whole electron gun and the...

AI Technical Summary

Problems solved by technology

The lead wire of the electron gun is welded on the sealing ring. The whole electron gun is potted with silicone rubber. The silicone rubber surrounds the whole electron gun and the tube to seal off the knife edge. The weight of the silicone rubber is as high as tens of grams. The large volume after potting is not conducive to the miniaturization of the whole tube and lightweight

In addition, there are many exposed high-voltage components that need to be potted in the laminated electron gun structure, and the insulation reliability is poor.
