preparation example Construction

[0039] Based on the same inventive concept, the present invention provides a method for preparing the collector of a space traveling wave tube, including the steps:

[0040] (1) Open a small hole at the bottom of the collector;

[0041] (2) Covering a metal sheet on the small hole to form a hermetic seal between the metal sheet and the small hole.

[0042] Based on the same inventive concept, the present invention provides a method for manufacturing a space traveling wave tube, which is characterized by including the following steps:

[0043] (1) Open a small hole at the bottom of the collector;

[0044] (2) Covering a metal sheet on the small hole to form a closed space between the metal sheet and the small hole;

[0045] (3) Weld the collector covered with the metal sheet with the slow wave component, and weld the slow wave component with the electron gun, and the electron gun is aligned with the metal sheet.

[0046] Further, in the above preparation method, after step (3), it includes...

Abstract

The invention relates to a controller of a space traveling wave tube, wherein a small hole is arranged on the bottom of the collector, and the small hole is hermetically covered by a metal sheet, which is equal to arrange a window. The invention also comprises a preparation of the collector and a space traveling wave tube comprising the collector. The window of the collector can leak gas after electron bombardment for a period of time, the residual gas in the space traveling wave tube enters space with 1*10<-8> Pa vacuum degree through an opened window; so that limiting vacuum of the space traveling wave tube is greatly improved, the service live of parts can be further greatly prolonged, and enormous economic benefits are produced. According to the invention, the tube, collector and method have advantages of simpleness, easy operation, low cost and high economic value.

Description

Technical field [0001] The invention relates to a long-life space traveling wave tube technology, in particular to a space traveling wave tube and its collector, and also relates to a preparation method of the traveling wave tube and the collector. Background technique [0002] The long-life space traveling wave tube is widely used in radar, satellite communication, global positioning, etc. Its unique function and superior performance, especially in the case of high power and high frequency, cannot be replaced by other devices. [0003] For the long-life space traveling wave tube, in view of its structure, process characteristics and general working principle, after eliminating the early failure, the device performance parameters tend to be stable. In addition, the vacuum device is not sensitive to environmental factors such as temperature and radiation, and the lifetime becomes An important indicator of its reliability level. There are many factors that affect the life of electri...
