Ukuhlukaniswa kwama-X-ray Tubes
Ngokwendlela yokukhiqiza ama-electron, amashubhu e-X-ray angahlukaniswa ngamashubhu agcwele igesi kanye namashubhu e-vacuum.
Ngokwezinto zokuvala ezahlukene, ingahlukaniswa ibe yishubhu yengilazi, ishubhu ye-ceramic kanye neshubhu ye-ceramic yensimbi.
Ngokusebenzisa okuhlukile, ingahlukaniswa ngamapayipi e-X-ray yezokwelapha kanye namapayipi e-X-ray ezimboni.
Ngokwezindlela ezahlukene zokuvala, ingahlukaniswa ngamapayipi e-X-ray avulekile kanye namapayipi e-X-ray avaliwe. Amapayipi e-X-ray avulekile adinga i-vacuum eqhubekayo ngesikhathi sokusetshenziswa. Ipayipi le-X-ray elivaliwe livalwa ngokushesha ngemva kokuhlanza ngezinga elithile ngesikhathi sokukhiqizwa kwepayipi le-X-ray, futhi asikho isidingo sokuhlanza futhi ngesikhathi sokusetshenziswa.
Amashubhu e-X-ray asetshenziswa kwezokwelapha ukuxilongwa nokwelashwa, kanye nobuchwepheshe bezimboni ukuhlola izinto ezingabhubhisi, ukuhlaziywa kwesakhiwo, ukuhlaziywa kwe-spectroscopic kanye nokuvezwa kwefilimu. Ama-X-ray ayingozi emzimbeni womuntu, futhi kumele kuthathwe izinyathelo zokuzivikela ezisebenzayo lapho uwasebenzisa.
Isakhiwo seshubhu ye-X-ray ye-anode engaguquki
Ishubhu ye-X-ray ye-anode engaguquki uhlobo olulula kakhulu lweshubhu ye-X-ray esetshenziswa njalo.
I-anode iqukethe ikhanda le-anode, isivalo se-anode, indandatho yengilazi kanye nesibambo se-anode. Umsebenzi oyinhloko we-anode ukuvimba ukugeleza kwama-electron ahamba ngesivinini esikhulu ebusweni bekhanda le-anode (ngokuvamile ithagethi ye-tungsten) ukuze kukhiqizwe imisebe ye-X, kanye nokukhipha ukushisa okuvelayo noma ukukuhambisa ngesibambo se-anode, kanye nokumunca ama-electron esibili kanye nama-electron ahlakazekile. Imisebe.
I-X-ray ekhiqizwa yi-tungsten alloy X-ray tube isebenzisa kuphela ngaphansi kwe-1% yamandla okugeleza kwe-electron ehamba ngesivinini esikhulu, ngakho-ke ukushabalaliswa kokushisa kuyinkinga ebaluleke kakhulu kwi-X-ray tube. I-cathode yakhiwe kakhulu yi-filament, i-focusing mask (noma ebizwa ngokuthi i-cathode head), i-cathode sleeve kanye ne-glass stem. Ugongolo lwe-electron oluhlasela i-anode target lukhishwa yi-filament (ngokuvamile i-tungsten filament) ye-hot cathode, futhi lwakhiwa ngokugxila yi-focusing mask (cathode head) ngaphansi kokusheshisa kwe-voltage ephezulu ye-tungsten alloy X-ray tube. Ugongolo lwe-electron oluhamba ngesivinini esikhulu lushaya i-anode target futhi luvaleke ngokuzumayo, okukhiqiza ingxenye ethile ye-X-rays enokusabalalisa kwamandla okuqhubekayo (kufaka phakathi i-X-rays ephawulekayo ekhombisa insimbi ye-anode target).
