Ubwino
● Mphamvu yabwino yoyimitsa
● Kuwala kwambiri
● Kuwala kochepa
● Nthawi yowonongeka
Kugwiritsa ntchito
● Kamera ya Gamma
● PET, PEM, SPECT, CT
● Kuzindikira kwa X-ray & Gamma ray
● Kuyang'ana kotengera mphamvu zamphamvu

GAGG:Ce (Gd3Al2Ga3O12) gadolinium aluminium gallium garnet yokhala ndi cerium.Ndi scintillator yatsopano ya single photon emission computed tomography (SPECT), gamma-ray ndi Compton electron kuzindikira.Cerium doped GAGG:Ce ili ndi zinthu zambiri zomwe zimapangitsa kuti ikhale yoyenera pazithunzithunzi za gamma ndi zojambula zamankhwala.Kuchulukirachulukira kwa mafotoni komanso nsonga yotulutsa pafupifupi 530 nm kumapangitsa kuti zinthuzo zikhale zoyenera kuwerengedwa ndi zowunikira za Silicon Photo-multiplier.Epic crystal idapanga mitundu 3 ya GAGG: Ce crystal, yokhala ndi nthawi yovunda mwachangu (GAGG-FD) kristalo, kristalo wamba (GAGG-Balance), kristalo wowala kwambiri (GAGG-HL) kristalo, kwa makasitomala osiyanasiyana.GAGG: Ce ndi scintillator wodalirika kwambiri m'mafakitale apamwamba kwambiri, pamene adayesedwa pa kuyesa kwa moyo pansi pa 115kv, 3mA ndi gwero la radiation lomwe lili pamtunda wa 150 mm kuchokera ku crystal, pambuyo pa maola 20 ntchitoyo imakhala yofanana ndi yatsopano. imodzi.Zimatanthawuza kuti ili ndi chiyembekezo chabwino chopirira mlingo waukulu pansi pa X-ray ray, inde zimatengera mikhalidwe yoyatsira komanso ngati kupitilira ndi GAGG kwa NDT kuyezetsa kwina kuyenera kuchitidwa.Pambali pa GAGG imodzi: Ce crystal, timatha kuyipanga kukhala mizere yozungulira ndi 2 dimensional, kukula kwa pixel ndi olekanitsa zitha kupezedwa potengera zofunikira.Tapanganso ukadaulo wa ceramic GAGG: Ce, ili ndi nthawi yabwinoko yothetsa mwangozi (CRT), nthawi yowola mwachangu komanso kutulutsa kwapamwamba kwambiri.
Kusintha kwamphamvu: GAGG Dia2"x2", 8.2% Cs137@662Ku
Afterglow performance
Kuwala linanena bungwe ntchito
Kusintha Kwanthawi: Gagg Fast Kuwola Nthawi
(a) Kusintha kwanthawi: CRT=193ps (FWHM, zenera lamphamvu: [440keV 550keV])
(a) Kuthetsa nthawi Vs.kukondera voteji: (zenera mphamvu: [440keV 550keV])
Chonde dziwani kuti kutulutsa kwapamwamba kwa GAGG ndi 520nm pomwe masensa a SiPM adapangidwira makhiristo okhala ndi 420nm peak emission.PDE ya 520nm ndi 30% yotsika poyerekeza ndi PDE ya 420nm.CRT ya GAGG ikhoza kusinthidwa kuchoka ku 193ps (FWHM) mpaka 161.5ps (FWHM) ngati PDE ya SiPM sensors ya 520nm ingagwirizane ndi PDE ya 420nm.
