Description
Technical field
This disclosure relates to be worn in microwave electron tube technical field, more particularly to a kind of miniaturization, the lead of light weight
Formula multi-level depressurization collector.
Background technology
Travelling-wave tubes (can be readily available several as highly important microwave power device because its individual devices working frequency is wide
The bandwidth of individual octave, is suitable for electronic warfare and uses), output power, efficiency high, 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 Geng Gao efficiency are various to apply what is showed to become jointly
Gesture.Especially for space measurement and satellite communication space travelling wave tube, due to the finiteness of energy supply, travelling-wave tubes effect is improved
Rate turns into the problem of travelling-wave tubes development first has to concern with production.
The general principle of travelling-wave tubes is electromagnetic wave interaction synchronous with electronics note, and electronics note energy is converted into microwave 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
Into thin electron beam, through helix radio frequency system;Slow wave system reduces controlling electromagnetic wave phase velocity, realizes that electronics is moved in radio frequency system
Microwave energy can be converted into, signal is amplified;Exaggerated microwave enters antenna transmission systems by delivery of energy coupled system;
The electron beam of portion of energy is surrendered, multi-level depressurization collector is finally entered, is decelerated before collector is reached, portion of energy is obtained
To recovery;Remaining electron energy is converted into heat energy in collector.Wherein, the effect of multi-level depressurization collector is to reclaim to pass through
The remaining kinetic energy in electronics note after Beam and wave interaction, so as 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, the volume and weight of collector is bigger.Therefore, design easily assembling, high efficiency, miniaturization, gently
The multi-level depressurization collector of weight is the important step in whole travelling-wave tubes design.
In addition, in recent years, a kind of concept of the Microwave Power Module of new integrated, modularization and miniaturization is occurred in that,
And it has been rapidly reached practical level.The main feature of Microwave Power Module is exactly to minimize.Such as, Northrop Grumman
The volume of Corporation 6-18GHz Microwave Power Module 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 is more easily realized, therefore efficient multi-level depressurization collector
Diameter often reaches 40mm~60mm.Such collector size limits its application in microwave and millimeter wave power model.
