Ce: YAG - Crystal Yingenzi

Ce: YAG ningirakamaro ya scintillation kristal hamwe nibikorwa byiza bya scintillation. Ifite urumuri rwinshi kandi rugari optique. Inyungu nini nuko uburebure bwacyo hagati ya luminescence ari 550nm, ishobora guhuzwa neza nibikoresho byo gutahura nka fotodi ya silicon. Ugereranije na CsI scintillation kristal, Ce: YAG scintillation kristal ifite igihe cyo kubora byihuse, na Ce: YAG scintillation kristal nta deliquescence, irwanya ubushyuhe bwinshi, hamwe nubushobozi buhamye bwa termodinamike. Ikoreshwa cyane cyane mugutahura ibice byoroheje, kumenya alpha ibice, gamma ray detection nibindi bice. Mubyongeyeho, irashobora kandi gukoreshwa mumashusho yerekana amashanyarazi (SEM), ecran ya microscopique yerekana amashusho ya fluorescent ya ecran nizindi nzego. Bitewe na coefficient ntoya yo gutandukanya Ce ion muri matrike ya YAG (hafi 0.1), biragoye kwinjiza Ce ion muri kristu ya YAG, kandi ingorane zo gukura kwa kirisiti ziyongera cyane hamwe no kwiyongera kwa diameter.
Ce: YAG kristu imwe ni ibikoresho byihuta-byangirika bifite ibintu byiza byuzuye, bifite urumuri rwinshi (fotone 20000 / MeV), kwangirika kwinshi (~ 70ns), ibintu byiza bya termo-mashini, hamwe nuburebure bwumurambararo (540nm) Nibyiza. ihujwe no kwakira ibyiyumvo byoroheje byumuyoboro usanzwe wa fotomultiplier (PMT) na silicon Photodiode (PD), urumuri rwiza rutandukanya imirasire ya gamma nuduce twa alfa, Ce: YAG ikwiranye no kumenya uduce twa alfa, electron na imirasire ya beta, nibindi. Imiterere yibice byashizwemo, cyane cyane Ce: YAG kristu imwe, ituma bishoboka gutegura firime zinini zifite umubyimba uri munsi ya 30um. Ce: Ikimenyetso cya YAG scintillation ikoreshwa cyane muri microscopi ya electron, kubara beta na X-ray, electron na X-ray yerekana amashusho nizindi nzego.
