At present, the material of emitting cathode is mostly present with big escaping powers low reliability 1ow uniformity and emission capability
摘要目前,陰極發射體材料多存在逸出功大,可靠性及均勻性低,發射性能低、不能自動調節活性物質更替的速度等方面的問題。To find a proper and convenient way in electron emitter research, in the paper, we have discussed the essential and possibility of setting up a new pld ( pulsed laser deposition ) device which connects with aes ( auger energy spectra ), and built such device in order to complete cathode deposition and analysis without exposing to the atmosphere and carried out cathode in - situ preparation and analysis electron emission phenomenon is a physical process taken place in surface of electron emitter
為了解決電子發射體(陰極)研究方法中存在的問題,並尋求一種適當的、方便的陰極研究實驗方法,本論文論證了建立與aes相連的pld裝置的必要性和可行性,並實際建立了這一裝置,實現了陰極的原位沉積、原位分析。電子發射現象是在電子發射體表面發生的物理過程,發射表面是由活性元素構成的動態平衡系統,這一系統直接決定電子發射性能。表面分析手段對陰極研究是必不可少的。The properties of these doped powders, the microstructure and composition of these rare - earth co - doped tungsten matrices and cathodes have been investigated by size analysis, xrd, sem and edax. the electronic emission performances of these cathodes are measured in uhv electron emission surveyor. aes is adopted to analyze the atom composition and diffusion behavior of active elements on cathode surfaces
通過粒度分析、 xrd 、 sem 、 edax研究了摻雜粉末的特性、燒結基體和陰極的微觀結構和成分;用動態真空電子發射測試儀對上述陰極進行了電子發射水平的測試;採用aes對陰極表面原子組成和活性物質的擴散行為進行了研究,分析了陰極發射水平與表面原子組成的關系。
