Txias-cathode X-ray tshuab tuaj yeem cuam tshuam kev lag luam kev kho mob

Txias cathode X-ray tshuab muaj lub peev xwm los hloov kho X-ray raj tshuab, yog li cuam tshuam rau kev lag luam duab kho mob. X-ray raj yog ib qho tseem ceeb ntawm cov khoom siv kho mob, siv los tsim cov x-rays xav tau los tsim cov duab kuaj mob. Cov thev naus laus zis tam sim no tso siab rau cov cathodes rhuab, tab sis cov tshuab txias-cathode sawv cev rau qhov kev ua si hloov pauv hauv daim teb no.

Ib txwmX-ray tubes ua hauj lwm los ntawm cua sov ib tug filament mus rau ib tug high kub, uas ces emits electrons. Cov electrons no tau nrawm rau ntawm lub hom phiaj, feem ntau yog ua los ntawm tungsten, ua X-rays thaum muaj kev cuam tshuam. Txawm li cas los xij, cov txheej txheem no muaj ntau qhov tsis zoo. Qhov kub thiab txias yuav tsum tau emit electrons txwv lub neej ntawm cov hlab, raws li cov cua kub thiab txias tas li ua rau thermal stress thiab degradation. Tsis tas li ntawd, cov txheej txheem cua sov ua rau nws nyuaj kom tig lub raj X-ray sai sai, ua rau lub sijhawm xav tau rau cov txheej txheem duab.

Nyob rau hauv sib piv, txias cathode X-ray tshuab siv lub teb emission electron qhov chaw thiab yuav tsum tsis muaj cua sov. Hloov chaw, cov tshuab no tsim cov khoom siv hluav taws xob los ntawm kev siv lub tshuab hluav taws xob mus rau lub ntsej muag cathode ntse, ua rau cov hluav taws xob emission vim quantum tunneling. Txij li thaum lub cathode tsis yog cua sov, lub neej ntawm X-ray raj yog txuas ntxiv, muab cov peev txheej txuag nyiaj rau cov chaw kho mob.

Tsis tas li ntawd, txias cathode X-ray tshuab muaj lwm yam zoo. Lawv tuaj yeem qhib thiab kaw sai sai, tso cai rau kom muaj txiaj ntsig zoo dua. Cov raj X-ray ib txwm xav tau lub sijhawm sov so tom qab hloov pauv, uas tuaj yeem siv sijhawm sijhawm thaum muaj xwm txheej ceev. Nrog rau cov kab mob cathode txias, kev yees duab tuaj yeem ua tau tam sim ntawd, muaj peev xwm txuag lub sijhawm tseem ceeb hauv cov xwm txheej kho mob tseem ceeb.

Tsis tas li ntawd, vim tias tsis muaj qhov cua sov filament, tsis tas yuav tsum muaj qhov cua txias, txo qhov nyuaj thiab qhov loj ntawm cov khoom siv X-ray. Qhov no tuaj yeem ua rau kev txhim kho cov cuab yeej siv tau yooj yim thiab cov duab me me, ua rau kev kho mob yooj yim dua thiab yooj yim dua hauv ntau qhov chaw, suav nrog cov chaw nyob deb lossis chaw kho mob mobile.

Txawm hais tias muaj peev xwm loj ntawm cov kab mob khaub thuas cathode X-ray, tseem muaj qee qhov teeb meem uas yuav tsum tau daws. Field emission cathode cov lus qhia tsis yooj yim, puas yooj yim, thiab yuav tsum tau ceev faj tuav thiab tu. Tsis tas li ntawd, cov txheej txheem quantum tunneling tuaj yeem tsim cov khoom siv hluav taws xob tsawg, uas tuaj yeem ua rau cov duab nrov thiab txo qhov zoo ntawm X-ray duab. Txawm li cas los xij, kev tshawb fawb tsis tu ncua thiab thev naus laus zis nce qib txhawm rau txhawm rau kov yeej cov kev txwv no thiab muab cov kev daws teeb meem rau kev siv dav dav ntawm cov kab mob khaub thuas-cathode X-ray.

Kev lag luam duab kho mob muaj kev sib tw thiab hloov zuj zus mus tas li, nrog kev txhim kho thev naus laus zis tsav kev txhim kho hauv kev kuaj mob thiab kev kho mob. Txias cathode X-ray tshuab muaj peev xwm cuam tshuam rau kev lag luam no nrog cov txiaj ntsig tseem ceeb ntawm cov tshuab X-ray raj tshuab. Lub neej ntev, hloov pauv sai thiab txo qhov loj tuaj yeem hloov kho cov duab kho mob, txhim kho kev saib xyuas neeg mob thiab ua kom muaj txiaj ntsig tag nrho ntawm kev kho mob ib puag ncig.

Hauv kev xaus, txias cathode X-ray tshuab sawv cev rau kev cog lus tshiab uas tuaj yeem cuam tshuam kev lag luam kev kho mob. Los ntawm kev hloov cov rhuab filament technology ntawm tsoosX-ray tubes, cov tshuab no muaj lub neej ntev dua, kev hloov pauv sai, thiab muaj peev xwm rau cov khoom siv tau yooj yim dua. Thaum cov teeb meem tseem yuav daws tau, kev tshawb fawb tsis tu ncua txhawm rau kov yeej cov kev txwv no thiab ua kom txias cathode X-ray tshuab tus qauv hauv kev kho mob, txhim kho kev saib xyuas neeg mob thiab hloov pauv kev lag luam.
