Kugawa Machubu a X-ray
Malinga ndi njira yopangira ma elekitironi, machubu a X-ray amatha kugawidwa m'machubu odzazidwa ndi mpweya ndi machubu opumira.
Malinga ndi zipangizo zosiyanasiyana zosindikizira, zingagawidwe m'machubu agalasi, chubu cha ceramic ndi chubu chachitsulo cha ceramic.
Malinga ndi ntchito zosiyanasiyana, zitha kugawidwa m'machubu a X-ray azachipatala ndi machubu a X-ray a mafakitale.
Malinga ndi njira zosiyanasiyana zotsekera, zitha kugawidwa m'machubu otseguka a X-ray ndi machubu otsekedwa a X-ray. Machubu otseguka a X-ray amafuna vacuum yosalekeza panthawi yogwiritsa ntchito. Chubu chotsekedwa cha X-ray chimatsekedwa nthawi yomweyo mutachotsa vacuum pamlingo winawake panthawi yopanga chubu cha X-ray, ndipo palibe chifukwa chochotsera vacuum kachiwiri panthawi yogwiritsa ntchito.
Machubu a X-ray amagwiritsidwa ntchito mu zamankhwala pofufuza ndi kuchiza, komanso muukadaulo wamafakitale poyesa zinthu zosawononga, kusanthula kapangidwe kake, kusanthula kwa spectroscopic ndi kuwonetsedwa kwa filimu. Ma X-ray ndi owopsa kwa thupi la munthu, ndipo njira zodzitetezera ziyenera kutengedwa powagwiritsa ntchito.
Kapangidwe ka chubu cha X-ray cha anode yokhazikika
Chubu cha X-ray chokhazikika cha anode ndi mtundu wosavuta kwambiri wa chubu cha X-ray chomwe chimagwiritsidwa ntchito kwambiri.
Anode imakhala ndi mutu wa anode, chipewa cha anode, mphete yagalasi ndi chogwirira cha anode. Ntchito yayikulu ya anode ndikuletsa kuyenda kwa ma elekitironi oyenda mwachangu pamwamba pa mutu wa anode (nthawi zambiri chogwirira cha tungsten) kuti apange ma X-ray, ndikutulutsa kutentha komwe kumachitika kapena kuyendetsedwa kudzera mu chogwirira cha anode, komanso kuyamwa ma elekitironi ena ndi ma elekitironi omwazikana. Ma Rays.
X-ray yopangidwa ndi chubu cha X-ray cha tungsten alloy imagwiritsa ntchito mphamvu yochepera 1% yokha ya mphamvu ya kayendedwe ka ma elekitironi oyenda mwachangu, kotero kutayika kwa kutentha ndi nkhani yofunika kwambiri pa chubu cha X-ray. Cathode imapangidwa makamaka ndi ulusi, chigoba choyang'ana (kapena chotchedwa mutu wa cathode), chigoba cha cathode ndi tsinde lagalasi. Mtanda wa elekitironi womwe umagunda cholinga cha anode umatulutsidwa ndi ulusi (nthawi zambiri ulusi wa tungsten) wa cathode yotentha, ndipo umapangidwa poyang'ana ndi chigoba choyang'ana (mutu wa cathode) pansi pa kuthamanga kwamphamvu kwa chubu cha X-ray cha tungsten alloy. Mtanda wa elekitironi woyenda mwachangu umagunda cholinga cha anode ndipo umatsekedwa mwadzidzidzi, zomwe zimapangitsa gawo lina la ma X-ray okhala ndi kugawa kwamphamvu kosalekeza (kuphatikiza ma X-ray odziwika bwino omwe akuwonetsa chitsulo cha anode).
