Izicucu ze-Electron Beam Tungsten
Incazelo Yomkhiqizo
Izintambo ze-tungsten zinendawo yokuncibilika ephezulu, ukumelana okuphezulu, amandla amahle, kanye nomfutho ophansi womusi, futhi zingasetshenziswa ezinhlelweni zokuhwamuka kwezinsimbi ze-electron. Izintambo ze-tungsten zezinsimbi ze-electron zingamelana namazinga okushisa aphezulu akhiqizwa ngesikhathi senqubo yokuhwamuka, okuqinisekisa ukusebenza okuthembekile nokuphumelelayo kwenqubo yokuhwamuka.
Ama-filament e-tungsten e-electron beam ayingxenye ebalulekile ezinhlelweni zokufaka i-vacuum, ezisebenzisa amandla e-electron bombardment ukuze zishise izinto eziqondiwe. Le nqubo yokushiswa ikhiqiza umfudlana wama-athomu noma ama-molecule, afaka ifilimu encane enobunye obuhle kakhulu, ubuningi, kanye nobumsulwa.
Sakha i-tungsten kanye nezinye izintambo ze-OEM zezinhlelo ze-electron beam ezidumile, okuhlanganisa:
• I-JEOL
• I-Leybold
• I-Telemark
• I-Temescal
• I-Thermionic
Sisekela ukwenza ngokwezifiso imininingwane eminingi kanye nezimo. Sicela usithinte uma kudingeka.
Iphakheji ngokuvamile iba yibhokisi elilodwa (izingcezu eziyi-10), okuyi-MOQ encane kakhulu.
Izicelo
Ama-filament e-tungsten e-electron beam asetshenziswa kabanzi ezimbonini eziningi kanye nasemasimini afana nokukhiqiza ama-semiconductor, ama-optics, izindiza kanye nezimoto. Asetshenziselwa ukufaka amafilimu amancane ezinsimbi, ama-oxide nezinye izinto ezisetshenziswayo kuma-substrates ukuze kusetshenziswe njengezifunda ezihlanganisiwe, izembozo ze-optical, amaseli elanga kanye nama-topcoat okuhlobisa.
