Classification ntawm X-ray Tubes
Raws li txoj hauv kev tsim cov khoom siv hluav taws xob, X-ray raj tuaj yeem muab faib ua cov raj roj thiab lub tshuab nqus tsev.
Raws li cov ntaub ntawv sib txawv, nws tuaj yeem muab faib ua iav raj, raj ceramic thiab hlau ceramic raj.
Raws li kev siv sib txawv, nws tuaj yeem muab faib ua cov raj xa hluav taws xob kho mob thiab cov raj xa hluav taws xob muaj.
Raws li cov txheej txheem sib txawv, nws tuaj yeem muab faib ua cov raj xa hluav taws xob qhib thiab kaw cov raj xa hluav taws xob.Qhib X-ray raj xav tau lub tshuab nqus tsev tas li thaum siv.Lub raj xa hluav taws xob kaw tau kaw tam sim tom qab nqus tsev rau qee qhov thaum lub sij hawm tsim cov X-ray raj, thiab tsis tas yuav tsum nqus rov qab thaum siv.
X-ray raj yog siv rau hauv cov tshuaj rau kev kuaj mob thiab kev kho mob, thiab hauv kev lag luam thev naus laus zis rau kev sim tsis muaj kev puas tsuaj ntawm cov ntaub ntawv, kev txheeb xyuas cov qauv, kev tsom xam spectroscopic thiab raug zaj duab xis.X-rays muaj teeb meem rau tib neeg lub cev, thiab kev tiv thaiv zoo yuav tsum tau ua thaum siv lawv.
Cov qauv ntawm taag anode X-ray raj
Tsau anode X-ray raj yog qhov yooj yim tshaj plaws ntawm X-ray raj hauv kev siv.
Lub anode muaj anode taub hau, anode cap, iav nplhaib thiab anode kov.Lub ntsiab lus tseem ceeb ntawm anode yog los thaiv lub siab ceev txav electron ntws los ntawm anode lub taub hau (feem ntau yog lub hom phiaj tungsten) los ua kom sov los yog coj los ntawm anode kov, thiab tseem nqus cov hluav taws xob theem nrab thiab cov hluav taws xob tawg.Rays.
X-ray generated los ntawm tungsten alloy X-ray raj tsuas yog siv tsawg dua 1% ntawm lub zog ntawm cov high-speed tsiv electron txaus, yog li cov cua kub dissipation yog ib qho teeb meem tseem ceeb heev rau X-ray raj.Lub cathode feem ntau yog tsim los ntawm ib lub filament, lub ntsej muag tsom (los yog hu ua lub taub hau cathode), lub tes tsho cathode thiab lub iav qia.Cov kab hluav taws xob tawg ua rau lub hom phiaj anode yog tawm los ntawm cov filament (feem ntau tungsten filament) ntawm cov cathode kub, thiab yog tsim los ntawm tsom los ntawm lub ntsej muag tsom (cathode taub hau) nyob rau hauv lub high voltage acceleration ntawm tungsten alloy X-ray raj.Lub high-speed txav electron beam hits lub hom phiaj anode thiab yog dheev thaiv, uas ua rau ib feem ntawm X-rays nrog tas mus li zog tis (nrog rau cov yam ntxwv X-rays reflecting lub anode phiaj hlau).
