Ukuhlukaniswa kwama-X-ray Tubes
Ngokwendlela yokukhiqiza ama-electron, amashubhu e-X-ray angahlukaniswa abe amashubhu agcwele igesi namashubhu e-vacuum.
Ngokwezinto ezihlukene zokuvala uphawu, zingahlukaniswa zibe ithubhu yengilazi, ishubhu ye-ceramic kanye neshubhu lensimbi ye-ceramic.
Ngokusetshenziswa okuhlukene, ingahlukaniswa ngamashubhu e-X-ray ezokwelapha kanye namashubhu e-X-ray ezimboni.
Ngokwezindlela ezihlukene zokuvala, ingahlukaniswa ngamashubhu e-X-ray avulekile namashubhu e-X-ray avaliwe. Amashubhu e-X-ray avulekile adinga i-vacuum eqhubekayo ngesikhathi sokusetshenziswa. Ishubhu le-X-ray elivaliwe liyavalwa ngokushesha ngemva kokucocwa ngezinga elithile phakathi nokukhiqizwa kweshubhu le-X ray, futhi asikho isidingo sokuphinda kucwecwe ngesikhathi sokusetshenziswa.
Amashubhu e-X-ray asetshenziswa kwezokwelapha ukuxilongwa nokwelashwa, kanye nakwezobuchwepheshe bezimboni zokuhlola okungabhubhisi izinto, ukuhlaziywa kwesakhiwo, ukuhlaziywa kwe-spectroscopic kanye nokuvezwa kwefilimu. Ama-X-ray ayingozi emzimbeni womuntu, futhi izinyathelo zokuzivikela eziphumelelayo kufanele zithathwe lapho uwasebenzisa.
Ukwakheka kweshubhu ye-X-ray ye-anode engashintshi
Ishubhu ye-X-ray ye-anode engaguquki iwuhlobo olulula lweshubhu le-X-ray elisetshenziswa kakhulu.
I-anode iqukethe ikhanda le-anode, ikepisi le-anode, indandatho yengilazi nesibambo se-anode. Umsebenzi oyinhloko we-anode ukuvimbela ukugeleza kwe-electron ehamba ngesivinini esiphezulu ngendawo eqondiwe yekhanda le-anode (imvamisa ithagethi ye-tungsten) ukuze kukhiqizwe ama-X-ray, nokukhipha ukushisa okuwumphumela noma ukuyihambisa ngesibambo se-anode, futhi imunca ama-electron esibili nama-electron ahlakazekile. Imisebe.
I-X-ray ekhiqizwe ishubhu ye-X-ray ye-tungsten alloy isebenzisa kuphela angaphansi kuka-1% wamandla okugeleza kwe-electron ehamba ngesivinini esiphezulu, ngakho ukunqanyulwa kokushisa kuyindaba ebaluleke kakhulu yeshubhu le-X-ray. I-cathode ikakhulukazi yakhiwe i-filament, imaski egxilile (noma ebizwa ngokuthi ikhanda le-cathode), umkhono we-cathode kanye nesiqu sengilazi. I-electron beam eqhuma i-anode target ikhishwa umcu (ngokuvamile i-tungsten filament) ye-cathode eshisayo, futhi yakhiwe ngokugxila imaski egxilile (ikhanda le-cathode) ngaphansi kokusheshisa kwe-voltage ephezulu ye-tungsten alloy X-ray tube. Insimbi ye-electron ehamba ngesivinini esiphezulu ishaya ithagethi ye-anode futhi ivinjwe kungazelelwe, ekhiqiza ingxenye ethile yama-X ray ngokusatshalaliswa kwamandla okuqhubekayo (kuhlanganise nesici se-X-ray ebonisa insimbi eqondiwe ye-anode).
