Beryllium x-ray windows yog siv los tiv thaiv lub tshuab ntes thaum tib lub sijhawm thaiv cov hluav taws xob tsis xav tau thiab yog li muab qhov tsawg kawg nkaus ntawm cov teeb liab xav tau. Beryllium has very tiny atoms and very low density and thus absorbs relatively few X-rays as opposed to other materials. Ib tug yam ntxwv uas ua rau lawv haum rau qhov siab tshaj plaws flux kis tau tus mob thiab e tshwj xeeb uas tsis tshua muaj zog kis tau tus mob yog xav tau.
Beryllium muaj txiaj ntsig zoo rau x-ray optics vim x-ray absorption scales li Z2Z2 (Z yog tus naj npawb ntawm electrons ntawm lub atom) yog li Be (Z=4Z=4) yog nyob rau hauv txoj cai txawm zoo dua pob zeb diamond (Z=6Z=6 ), pheej yig dua, thiab yooj yim rau tshuab. Lawv yog siv rau lub qhov rais rau lub tshuab nqus tsev chambers thiab cryogenic chambers, los tiv thaiv x-ray detectors ntawm chav tsev teeb, laser teeb (thiab tej zaum greasy scientist ntiv tes). Lawv kuj tuaj yeem siv rau ntawm x-ray raj thiab ntawm synchrotrons kom cov electrons uas tsim x-rays nyob rau hauv lub tshuab nqus tsev, thaum cia cov x rays rau hauv huab cua.
Hnub no, peb yuav tau txais kev: peb tab tom tham txog kev ua haujlwm ntawm X-ray raj; thiab yam twg koj yuav tsum paub raws li tus neeg yuav khoom X-ray systems, kom nkag siab tias cov neeg muag khoom sib txuas lus rau koj li cas.
X-Ray Window Tubes:
Ib qho tseem ceeb tshaj plaws uas yuav tsum paub txog kev tsim ntawm X-ray raj yog tias lawv yog cov teeb pom kev zoo hauv lub tshuab nqus tsev. Txawm li cas los xij, nyob rau sab nraud ntawm lub raj yog ib hom "qhov rais" uas yog qhov aperture, lossis txoj kev, rau X-ray lub zog tawm ntawm lub raj thiab nkag mus rau koj qhov chaw kuaj xyuas.
Cov apertures no yog tsim los ntawm ob hom khoom: iav thiab beryllium ("Be"). Beryllium yog cov hlau lightest nyob rau hauv lub rooj atomic. Muaj cov yam ntxwv sib txawv ntawm X-ray raj nyob ntawm seb hom aperture sealant koj muaj.
Tsawg-Nergy Photons
X-ray lub zog zoo li lub tswb nkhaus. Kev faib tawm yog qhov tseem ceeb ntawm lub zog ntawm photons. Wb hais tias koj muaj X-ray raj ntsuas ntawm 70 KV. Koj yuav, tau kawg, muaj qee qhov photons nrog lub zog ntau dua, thiab qee qhov muaj tsawg dua. Tsawg zog photons yog cov uas tsis tshua muaj peev xwm dhau los ntawm ib yam dab tsi yam tsis ua rau lub ntes pom lawv. Qhov ntawd suav nrog cov khoom tsis tshua muaj xws li yas, pob txha, thiab qee lub pob zeb. Yog tias koj tab tom sim nrhiav cov khoom no, lub raj beryllium X-ray raj zoo dua rau iav vim tias iav raj lim tawm qis-zog photons. Qhov ntawd yog iav yog: lub lim.
Yog hais tias koj xav txog ib tug qaib mis nrog ib tug pob txha nyob rau hauv nws, nrog ib tug iav raj koj yuav tsis pom dab tsi; koj lub thawv duab yuav tsis muaj. Tab sis nrog ib lub raj beryllium, koj yuav pom cov pob txha nrog clarity.
Beryllium Qhov rai Tubes
Yog tias koj xav tau qis -zog photons, koj xav tau lub raj beryllium photon. Yog li yog tias koj tab tom yuav X-ray raj thiab koj xav tau qee yam kev kuaj pom muaj kab mob, nws tseem ceeb heev kom txaus siab rau tus nqi ntawm beryllium qhov rais raj.
Lawv tsis muaj los ntawm txhua tus neeg tsim khoom - tab sis yitech trading muaj txhua yam ntawm beryllium windows nrog txhua yam ntawm cov duab. Peb txais HIP los ua cov khoom lag luam beryllium thiab peb cov purity ntawm beryllium tuaj yeem rach 99.9%.
Beryllium qhov rais raj yog kim dua los ua. Tab sis lawv cov kev ua tau zoo rau qee yam kev siv yog superior. Yog li yog tias koj daim ntawv thov tuaj yeem siv beryllium qhov rai raj, peb xav kom koj tham nrog peb.
