Yintoni i-anode ejikelezayo? Lo mbuzo udla ngokubuzwa xa kuxoxwa ngemiba yobugcisa yeetyhubhu ze-X-ray. Kweli nqaku, siza kungena nzulu kwingcamango yeiityhubhu ze-X-ray ze-anode ezijikelezayokwaye uphonononge impembelelo yazo kwimifanekiso yezonyango.
Imifanekiso ye-X-ray itshintshe kakhulu kwicandelo lezonyango ngokuvumela oogqirha ukuba babone izakhiwo zangaphakathi ngaphandle kokwenza utyando oluhlaselayo. Iityhubhu ze-X-ray ziphambili kolu buchwepheshe kwaye zivelisa ii-X-ray ezinamandla aphezulu afunekayo kule ndlela yokufota engahlaseliyo. I-anode ejikelezayo yinxalenye ebalulekileyo yezi tyhubhu ze-X-ray, nto leyo eyandisa ukusebenza kwazo kunye nobude bazo.
Ngoko ke, yintoni kanye kanye i-anode ejikelezayo? Ngamafutshane, yithagethi emile okwediski eyenziwe ngezinto eziphezulu zeathomu ezifana ne-tungsten okanye i-molybdenum. Ithagethi ijikeleza ngokukhawuleza ngexesha lokuveliswa kwe-X-ray, okuvumela ukuchithwa kobushushu okusebenzayo ngakumbi kunye nokwanda kwemveliso ye-X-ray.
Eyona njongo iphambili yee-anode ezijikelezayo kukunqoba imida yee-anode ezizinzileyo. Kwiityhubhu ze-X-ray ze-anode ezizinzileyo eziqhelekileyo, ubushushu obuveliswa ngexesha lokuveliswa kwe-X-ray bunqunyelwe kwindawo encinci kwi-anode. Obu bushushu buxineneyo buyawutshabalalisa ngokukhawuleza loo anode, bunciphise amandla kunye nobude bokuphuma kwe-X-ray. Ii-anode ezijikelezayo zisombulula le ngxaki ngokusasaza umthwalo wobushushu kwindawo enkulu, ngaloo ndlela zinciphisa ukuguguleka kwe-anode kwaye zandise ubomi beetyhubhu.
Uyilo lwee-anode ezijikelezayo lubandakanya ubunjineli obuntsonkothileyo. I-anode idla ngokwenziwa nge-tungsten kuba ineqondo eliphezulu lokunyibilika kwaye inokumelana nobushushu obukhulu obuveliswa xa kuveliswa ii-X-ray. Ukongeza, i-anode igqunywe ngomaleko omncinci wezinto ezingafunekiyo, ezifana ne-graphite okanye i-molybdenum, ukuphucula ukuhanjiswa kwayo kobushushu.
Ukujikeleza kwe-anode kwenziwa kusetyenziswa i-rotor kunye neebheringi. I-rotor eqhutywa yimoto yombane ijikeleza i-anode ngesantya esiphezulu, ngesiqhelo malunga ne-3,000 ukuya kwi-10,000 revolutions ngomzuzu. Iibheringi ziqinisekisa ukujikeleza okuthe tye nokuzinzileyo, naluphi na ukungalingani okanye ukungcangcazela kunokuchaphazela kakubi umgangatho womfanekiso.
Iingenelo zeetyhubhu ze-X-ray ze-anode ezijikelezayo zininzi. Okokuqala, i-anode ejikelezayo inendawo enkulu enokubususa ubushushu ngcono, ngaloo ndlela yandise amaxesha okuvezwa kwaye inyuse imveliso ye-X-ray. Oku kuthetha amaxesha amafutshane ovavanyo kunye nentuthuzelo enkulu yesigulana. Ukongeza, ukuqina kwe-anode ejikelezayo kuvumela ityhubhu ye-X-ray ukuba imelane nokusetyenziswa okuphindaphindiweyo nokude, okwenza ukuba ifaneleke kwizibonelelo zonyango ezinomthamo omkhulu.
Ukongeza, ukukwazi ukujolisa umqadi we-X-reyi kwindawo encinci ye-anode kwandisa ukusombulula kunye nokucaca kwemifanekiso evelayo. Oku kubaluleke kakhulu kwimifanekiso yokuxilonga, apho ukubonakala ngokuchanekileyo kwezakhiwo zomzimba kubalulekile. Amandla okusasaza ubushushu aphuculweyo e-anode ejikelezayo anceda ukufota okuqhubekayo ngaphandle kokuphazamiseka kokupholisa, nto leyo ephucula ngakumbi ukusebenza kakuhle komsebenzi.
Isishwankathelo,iityhubhu ze-X-ray ze-anode ezijikelezayo iguqule icandelo lemifanekiso yezonyango. Ngenxa yobunjineli bayo obuphambili kunye neempawu zayo zokusasaza ubushushu ezibalaseleyo, ezi tyhubhu zibonelela ngeenzuzo ezininzi kuneetyhubhu ze-anode ezisisigxina zemveli. Ukususela ekuphumeni kwe-X-ray eyongeziweyo kunye nobomi betyhubhu ende ukuya kwisisombululo esiphuculweyo somfanekiso, iityhubhu ze-X-ray ze-anode ezijikelezayo ziye zaba sisixhobo esibalulekileyo kwimpilo yanamhlanje.
