NaI(Tl) Scintillator, NaI(Tl) Crystal, NaI(Tl) Scintillation Crystal

Kufotokozera mwachidule:

NaI(Tl) ndizomwe zimagwiritsidwa ntchito kwambiri popangira scintillation chifukwa chotsika mtengo.Imakhala ndi kuwala kwapamwamba kwambiri, kuyendetsa bwino kwambiri, kukula kwakukulu komwe kulipo komanso kutsika mtengo kwambiri poyerekeza ndi zipangizo zina za scintillation.NaI(TI) ndi ya hygroscopic ndipo iyenera kuyikidwa m'nyumba (Stainless Steel, Titanium Alloy, Al housing alternative).

Mawonekedwe ndi Kukula kwake: Mapeto-chabwino, mawonekedwe a cubic, mbali yotseguka bwino, silinda.Dia1"x1", Dia2" x2, Dia3"x3", Dia5"x5", 2"x4"x16", 4"x4"x16", Anti-Compton detector.

Amapezeka mu crystal imodzi, polycrystalline kapena makhiristo opangira makina opangira mitengo yamafuta.

Ubwino

● Zotsika mtengo

● Kukula kwakukulu kulipo

● Kuwala kwakukulu / kuzindikira bwino

● Single / polycrystal/forged crystal ilipo

● Wavelength yogwirizana bwino ndi PMT yowerengedwa

● NaI(Tl) wopangira kristalo wodula mafuta

● MWD/LWD

Kugwiritsa ntchito

● Mankhwala a nyukiliya

● Miyezo ya chilengedwe

● Geophysics

● Fiziki yopatsa mphamvu kwambiri

● Kuzindikira ma radiation

NaI(Tl) imayimira sodium iodide doped ndi thallium.Ndi scintillation zinthu zomwe zimagwiritsidwa ntchito pozindikira ma radiation, makamaka cheza cha gamma.Pamene kuwala kwa gamma kugunda kristalo wa NaI(Tl), kumapangitsa kuti ma atomu a Tl atulutse kuwala kwa kuwala, komwe kumadziwika ndi photocathode ndikusinthidwa kukhala chizindikiro chamagetsi.NaI(Tl) imagwiritsidwa ntchito kwambiri poyang'anira gamma spectroscopy, kulingalira zachipatala, ndi kuyang'anira chilengedwe.

Polycrystalline scintillator ndi scintillator wopangidwa ndi timbewu tating'ono tating'ono ta kristalo m'malo mwa kristalo imodzi yayikulu ngati crystal scintillator imodzi.Tizigawo tating'onoting'ono timeneti timakula limodzi kudzera munjira yotchedwa solid-state sintering, momwe tinthu tating'onoting'ono timakumana ndi kutenthedwa mpaka kutentha kwambiri mpaka kusakanikirana.Izi ndizosiyana ndi njira imodzi yakukula kwa kristalo yomwe imagwiritsidwa ntchito pa ma crystal scintillators amodzi.Ma polycrystalline scintillators ali ndi maubwino angapo kuposa ma crystal scintillators amodzi, monga kutsika mtengo wopangira komanso kukhazikika kwamakina ndi kutentha.Komabe, amatha kukhala ndi mphamvu yocheperako komanso kutulutsa kocheperako poyerekeza ndi ma crystal scintillator.
