FlashCov raj xa duab X-ray yog cov khoom siv tshwj xeeb tsim los tsim cov pulses luv luv ntawm X-rays, feem ntau nyob rau hauv microsecond mus rau millisecond ntau yam. Cov sijhawm ceev ceev no yog qhov tshwj xeeb tshaj yog pab tau rau hauv cov ntawv thov uas xav tau kev thaij duab ceev ceev, xws li kev tshawb fawb dynamic ntawm cov khoom txav ceev lossis kev tshuaj xyuas cov khoom ntawm cov khoom siv hauv qab kev ntxhov siab. Lub peev xwm los ntes cov duab hauv cov sijhawm luv luv no tso cai rau kev tshuaj xyuas cov xwm txheej transient hauv kev nthuav dav ntxiv, ua rau cov raj X-ray flash tsis muaj txiaj ntsig zoo hauv kev tshawb fawb thiab kev teeb tsa kev lag luam.
Kev teeb tsa ntawm lub raj xa hluav taws xob X-ray
Qhov kev teeb tsa ntawm lub raj xa hluav taws xob X-ray yog qhov tseem ceeb rau nws txoj kev ua haujlwm thiab kev ua haujlwm zoo. Cov raj no feem ntau muaj ib lub cathode thiab ib lub anode uas kaw rau hauv lub hnab nqus tsev. Thaum cua sov, lub cathode tso tawm cov electrons, uas tom qab ntawd raug nrawm mus rau lub anode, qhov chaw uas lawv cuam tshuam thiab tsim cov X-rays. Cov qauv anode sib txawv, thiab qee qhov kev teeb tsa siv lub anode tig rau kev ua kom sov zoo dua, yog li ua rau lub raj siv tau ntev dua.
Ib qho txiaj ntsig tseem ceeb ntawm cov raj xa duab X-ray yog lawv txoj kev tsim me me, ua rau lawv yooj yim dua rau kev sib xyaw rau hauv cov kab ke uas twb muaj lawm. Qhov no tseem ceeb heev rau cov chaw uas muaj qhov chaw tsawg, xws li cov chaw kuaj mob lossis cov chaw tsim khoom. Ntxiv mus, ntau lub raj xa duab X-ray teeb tsa yog modular, txhais tau tias lawv tuaj yeem hloov kho tau yooj yim kom tau raws li cov kev xav tau tshwj xeeb, txawm tias kho qhov loj me ntawm qhov chaw lossis hloov kho lub zog tso zis ntawm lub raj.
Kev saib xyuas thiab kev saib xyuas yooj yim
Kev tswj hwm kev ua haujlwm ntawm lub raj xa duab X-ray yog qhov tseem ceeb heev rau kev ua kom cov duab zoo sib xws thiab ua kom lub neej ntawm cov khoom siv ntev dua. Cov raj xa duab X-ray Flash tau tsim los nrog kev saib xyuas kom yooj yim, tso cai rau cov kws kho tshuab ua haujlwm txij nkawm tsis tu ncua yam tsis muaj kev cuam tshuam rau kev ua haujlwm. Ntau lub tuam txhab tsim khoom muab cov phau ntawv qhia kev pabcuam thiab kev txhawb nqa, qhia txog cov txheej txheem ib kauj ruam zuj zus rau cov haujlwm txij nkawm, xws li hloov lub filament lossis rov kho lub raj.
Tsis tas li ntawd xwb, kev nce qib ntawm thev naus laus zis tau ua rau muaj kev tsim cov cuab yeej kuaj mob uas tuaj yeem saib xyuas kev noj qab haus huv ntawm lub raj xa duab X-ray hauv lub sijhawm tiag tiag. Cov cuab yeej no tuaj yeem ceeb toom cov neeg ua haujlwm txog cov teeb meem uas yuav tshwm sim ua ntej lawv loj hlob tuaj, ua rau muaj kev saib xyuas ua ntej thiab txo lub sijhawm tsis ua haujlwm. Qhov kev saib xyuas yooj yim no tsis yog tsuas yog txhim kho kev ntseeg tau ntawm cov raj xa duab X-ray Flash xwb tab sis kuj pab txuag cov nqi rau cov koom haum uas vam khom cov kab ke no rau cov haujlwm tseem ceeb.
