Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0019] Such as figure 2 As shown, it is a schematic diagram of a helical slow wave structure with strong heat dissipation capacity composed of a medium holding rod and a helix for depositing a diamond film of the present invention. The present invention uses a medium holding rod 1 for depositing a diamond film and a helix for depositing a diamond film 2 and the metal shell 3 form a slow wave component. Including: a medium clamping rod 1, a helix 2, a tube shell 3, a first diamond film 4 and a second diamond film 5, the inner wall of the tube shell 3 is in close contact with the diamond film 4 on the surface of the medium clamping rod 1, and the medium clamps The diamond film 4 on the surface of the rod 1 i...

Abstract

The invention discloses a helical line traveling wave tube slow-wave component and a preparation method thereof. The method comprises the steps as follows: a cleaned medium holding rod and the helical line are arranged in a diamond deposition chamber; the diamond is deposited on the surface of the medium holding rod and the helical line to form a diamond film; the medium holding rod and the helical line with the diamond film and a metal pipe shell are fixed on a loading die and extruded into the metal pipe shell. The component comprises the medium holding rod, the helical line, a pipe shell, a first diamond film and a second diamond film. The diamond is deposited on the surfaces of medium holding rod and the helical line, therefore, the defect of low heat conductivity of other mediums is compensated, the heat dissipation capability of the slow-wave component is improved, and the problems of difficult processing and expensive price of the diamond holding rod are solved.

Description

technical field [0001] The invention relates to the technical field of microwave devices, and relates to a helical traveling wave tube slow-wave component with strong heat dissipation capability. Background technique [0002] In the previous years of the Gulf War, the important role of advanced electronic technology in the war was fully demonstrated. In these several wars, the multinational forces used advanced electronic reconnaissance equipment and advanced electronic jamming equipment to make Iraqi electronic Jamming and communication equipment became "deaf" and "blind", leaving the multinational force with minimal aircraft and personnel casualties. Broadband and high-power traveling wave tubes are microwave devices that play a key role in the fields of electronic countermeasures, fire control systems and communications. Its performance plays a decisive role in these military and civilian systems, and the slow wave system determines the performance of traveling wave tubes...
