Ibisobanuro ku bicuruzwa
GAGG: Ce (Gd3Al2Ga3O12) gadolinium aluminium gallium garnet yuzuye hamwe na cerium.Ni scintillator nshya ya fotone imwe yoherejwe na tomografiya (SPECT), gamma-ray na Compton electronique.Cerium ikoporora GAGG: Ce ifite imitungo myinshi ituma ikwiranye na gamma spectroscopy hamwe nubuvuzi bwerekana amashusho.Umusaruro mwinshi wa fotone hamwe n’ibisohoka hejuru ya 530 nm bituma ibikoresho bikwiranye no gusomwa na Silicon Ifoto-igwiza.Epic kristal yateje imbere ubwoko 3 bwa GAGG: Ce kristal, hamwe nigihe cyo kubora vuba (GAGG-FD) kristu, isanzwe (GAGG-Balance) kristu, urumuri rwinshi rusohoka (GAGG-HL) kristu, kubakiriya mubice bitandukanye.AG imwe.Bivuze ko ifite ibyiringiro byiza byo guhangana nigipimo kinini munsi ya X-ray, birumvikana ko biterwa nimirasire kandi mugihe bigiye kure na GAGG kuri NDT hagomba gukorwa ikindi kizamini nyacyo.Kuruhande rwa GAGG imwe: Ce kristu, turashoboye kuyihimba mumurongo hamwe na 2 igizwe na array, ubunini bwa pigiseli nubutandukanya bishobora kugerwaho hashingiwe kubisabwa.Twateje imbere kandi tekinoroji ya ceramic GAGG: Ce, ifite amahirwe menshi yo gukemura igihe (CRT), igihe cyangirika vuba hamwe n’umucyo mwinshi.

Gukemura Igihe: Gagg Kwangirika Byihuse
(a) Gukemura igihe: CRT = 193ps (FWHM, idirishya ryingufu: [440keV 550keV])
(a) Icyemezo cyigihe V.kubogama kubogamye: (idirishya ryingufu: [440keV 550keV])
Nyamuneka menya ko imyuka ihumanya GAGG ari 520nm mugihe sensor ya SiPM yagenewe kristu hamwe na 420nm yohereza imyuka.PDE kuri 520nm iri munsi ya 30% ugereranije na PDE kuri 420nm.CRT ya GAGG irashobora kunozwa kuva 193ps (FWHM) ikagera kuri 161.5ps (FWHM) iyaba PDE ya sensor ya SiPM kuri 520nm yaba ihuye na PDE kuri 420nm.
