Description
Technical field
This disclosure relates to microwave electron tube technical field more particularly to it is a kind of miniaturization, light weight lead in wear
Formula multi-level depressurization collector.
Background technique
Travelling-wave tubes (can be easy to get several as highly important microwave power device because its individual devices working frequency is wide
The bandwidth of a octave is suitable for electronic warfare use), it is output power, high-efficient, therefore be widely used in electronic countermeasure, electricity
The fields such as sub- war, radar, meteorological observation, space measurement and satellite communication.In general, various applications are to devices such as travelling-wave tubes
It is required that being not quite similar.But generally speaking, higher power and higher efficiency be it is various apply showed become jointly
Gesture.Travelling-wave tubes effect is improved due to the finiteness of energy supply especially for space measurement and satellite communication space travelling wave tube
Rate becomes travelling-wave tubes development and production first has to the problem of paying close attention to.
The basic principle of travelling-wave tubes is electromagnetic wave interaction synchronous with electronics note, converts microwave energy for electronics note energy
Amount.
Travelling-wave tubes generally comprises electron gun, magnetic focusing system, slow-wave structure, delivery of energy coupled structure, single-stage or multilevel decompression
Five parts of collector.
The electronics gone out from emission of cathode, accelerates in electron gun, is compressed into electron beam, and maintained by Periodic magnetic focusing system
At thin electron beam, helix radio frequency system is passed through；Slow wave system reduces controlling electromagnetic wave phase velocity, realizes that electronics is dynamic in radio frequency system
It can be converted into microwave energy, amplify signal；The microwave being amplified enters antenna transmission systems by delivery of energy coupled system；?
The electron beam for surrendering portion of energy, finally enters multi-level depressurization collector, is decelerated before reaching collector, portion of energy obtains
To recycling；Remaining electron energy is converted into thermal energy in collector.Wherein, the effect of multi-level depressurization collector is that recycling is passed through
The remaining kinetic energy in electronics note after Beam and wave interaction, to greatly improve the gross efficiency of device.
Multi-level depressurization collector can greatly improve the efficiency of the vacuum electron devices such as travelling-wave tubes.Series is more, and ability is returned
Fruit of producing effects is better.But series is more, and the volume and weight of collector is bigger.Therefore, design easily assembly, high efficiency, miniaturization, gently

The volume of the Microwave Power Module of the 6-18GHz of Corporation is only 175mm × 140mm × 20mm.This means that installation
Traveling wave pipe diameter in the Microwave Power Module should be less than 20mm.
And as well known to the industry, traveling wave pipe diameter the best part is usually multi-level depressurization collector portion
Point.Because the diameter of multi-level depressurization collector is bigger, high efficiency more easy to accomplish, therefore efficient multi-level depressurization collector
Diameter often reaches 40mm~60mm.Such collector size limits its application in microwave and millimeter wave power module.
