Gulu la X-ray Tubes
Malinga ndi njira yopangira ma elekitironi, machubu a X-ray amatha kugawidwa kukhala machubu odzaza mpweya ndi vacuum chubu.
Malingana ndi zipangizo zosiyanasiyana zosindikizira, zikhoza kugawidwa mu chubu lagalasi, chubu cha ceramic ndi chubu chachitsulo cha ceramic.
Malinga ndi ntchito zosiyanasiyana, zikhoza kugawidwa m'magulu azachipatala a X-ray ndi mafakitale a X-ray.
Malinga ndi njira zosiyanasiyana zosindikizira, imatha kugawidwa m'machubu otseguka a X-ray ndi machubu otsekedwa a X-ray. Machubu otsegula a X-ray amafunikira vacuyumu nthawi zonse mukamagwiritsa ntchito. Chubu cha X-ray chotsekedwa chimamata mukangoumitsa pang'onopang'ono popanga chubu cha X-ray, ndipo sipafunikanso kutsukanso mukamagwiritsa ntchito.
Machubu a X-ray amagwiritsidwa ntchito pazamankhwala pozindikira ndi kuchiza, komanso muukadaulo wamafakitale pakuyesa kosawononga kwazinthu, kusanthula kwamapangidwe, kusanthula kwa spectroscopic ndikuwonetsa filimu. X-ray ndi yovulaza thupi la munthu, ndipo njira zodzitetezera ziyenera kuchitidwa mukazigwiritsa ntchito.
Mapangidwe a anode yokhazikika X-ray chubu
Fixed anode X-ray chubu ndi mtundu wosavuta wa X-ray chubu yomwe imagwiritsidwa ntchito nthawi zambiri.
Anode imakhala ndi mutu wa anode, kapu ya anode, mphete yagalasi ndi chogwirira cha anode. Ntchito yayikulu ya anode ndikuletsa kuthamanga kwa ma elekitironi othamanga kwambiri ndi chandamale cha mutu wa anode (nthawi zambiri chandamale cha tungsten) kuti apange ma X-ray, ndikuwunikira kutentha komwe kumachokera kapena kuwongolera kudzera pa chogwirira cha anode, komanso kuyamwa ma elekitironi achiwiri ndi ma elekitironi omwazikana. Miyezi.
X-ray yopangidwa ndi tungsten alloy X-ray chubu imangogwiritsa ntchito zosakwana 1% ya mphamvu ya kuthamanga kwa ma elekitironi othamanga kwambiri, kotero kuti kutaya kutentha ndi nkhani yofunika kwambiri pa chubu cha X-ray. Cathode imapangidwa makamaka ndi filament, chigoba cholunjika (kapena chotchedwa mutu wa cathode), manja a cathode ndi tsinde lagalasi. Mtengo wa elekitironi womwe ukuphulitsa chandamale cha anode umatulutsidwa ndi ulusi (nthawi zambiri tungsten filament) wa cathode yotentha, ndipo amapangidwa poyang'ana chigoba (mutu wa cathode) pansi pa mathamangitsidwe apamwamba a tungsten alloy X-ray chubu. The mkulu-liwiro kusuntha elekitironi mtengo kugunda chandamale anode ndipo mwadzidzidzi otsekedwa, amene umapanga gawo lina la X-ray ndi mosalekeza kugawa mphamvu (kuphatikizapo khalidwe X-ray kusonyeza anode chandamale zitsulo).
