Electron dogob alxanka - muuqaalada technology

In our teknoolojiyad sare da'da noqday madax adkaadeen badan, kulaylka u adkaysta, daxalka u adkaysta iyo shucaac-qalabka alxanka taas oo u baahan farsamooyin gaar ah. Sida electron alxanka ku jirase aad, kaas oo heerkulka aaga shaqo firfircoon gaadho kun jeer index ka badan hababka caadiga ah. heerkulka Ultrahigh ee noocan ah alxanka waxaa la gaari ay sabab u tahay photons ama electrons dhaqaaqin qolladdii vacuum ah xawaare ah oo ku saabsan 165 000 km / sec. Marka biraha la waaleen at a xawaaraha cajiib ah tamar ogeed oo ka mid ah qurubyada hoose waxaa beddelay kulaylka, oo wuu dhalaaliyaa biraha.

Electron alxanka dogob waa la fuliyay in qol gaar ah, kaas oo ah pre-gureeyay. Vacuum loo abuuray si electrons aan bixisay tamartaa ay by ionization walxo gaaska iyo in la helo welds kaamil ah oo aan inclusions biraha shisheeye. Electron dogob rakibo, tan waxaa lagu magacaabaa vacuum qolkii aan qalabaysnayn la gaar magnetic gashto, FURASHADA Jiheeyo socodka of electrons, oo wax ku ool ah maamulka. Sidoo kale siin qaybo welded oo waa hadiyad ku amraya dekedda.

Electron alxanka dogob la sameeyo talantaalli danab yar yahay hadda. Waxaa mara element gaar ah diiradda (lens), halkaas oo cathode si anode ah, iyo sidaas, dogobka ishaada electron la abuuray oo leh sifooyin la doonayo. In la rakibo low-xoog loo isticmaalo sidii galool cathode of tungsten ama tantalum ah. Haddii nidaamka iyo sifooyinka gaarka ah ee qalabka welded u baahan tahay awood dheeraad ah, halka horay u soo isticmaashay cathodes of cermet ama lanthanum hexaboride sameeyey isagoo awood dheeraad ah si ay warshadu hawada ku of electrons free.

Iyada oo ku xidhan muuqaalada dhismaha ee la rakibo, electron alxanka dogob in la sameeyo waxaa laga yaabaa in ay u dhaqaaqin wax in la sala welded si dogobka go'an ama dogob qeybsanaan ku xigeenka dhaqaajin karin qaraabo in ay qayb ka go'an. Sidoo kale, qaar ka mid ah design geedka siinayaa a deflectors gaar ah, taas oo ku siinayaa fursado badan si ay u helaan dun qaabeeya.

Tani nooca alxanka waxaa si balaadhan looga isticmaalaa in alxanka ee sare steels daawaha iyo Alloys titanium-ku salaysan iyo sidoo kale biraha sida molybdenum, tantalum, niobium, tungsten, zirconium, beryllium. Marka sax processing iyo alxanka ee mikrodetaley kala duwan. Waxa loo isticmaalaa in warshadaha sida sayniska gantaal, tamarta nukliyarka, alaabtii sax, microelectronics iyo kuwo kale oo badan.

Waxa intaa dheer in technology electron-dogobka waa mid baahsan, iyo alxanka laser. Qalabka loogu talagalay noocan ah ee alxanka - oscillator laser indhaha, taas oo ilo aalladda shucaac isku xidhan. Mabda'a ah alxanka laser ka duwan habka cathode-ray waa in aysan u baahan yihiin qolal vacuum waxaa loogu talagalay. habka alxanka by technology laser sameeyaa hawada ama qol ka yar shuruudaha u damaysay la gaaska gaar ah difaaca - carbon dioxide, argon iyo helium.
