Product Description
GAGG:Ce (Gd3Al2Ga3O12) gadolinium aluminium gallium garnet yakagadzirwa necerium.Iyo itsva scintillator yeimwe photon emission computed tomography (SPECT), gamma-ray uye Compton electron kuonekwa.Cerium doped GAGG: Ce ine zvakawanda zvivakwa zvinoita kuti ive yakakodzera gamma spectroscopy uye yekurapa imaging application.Goho repamusoro rephoton uye peak yekuburitsa yakatenderedza 530 nm inoita kuti zvinhu zvinyatsokodzera kuverengerwa neSilicon Photo-multiplier detectors.Epic crystal yakagadzira matatu marudzi eGAGG: Ce crystal, inokurumidza kuora nguva (GAGG-FD) crystal, yakajairika (GAGG-Balance) kristaro, yakakwira mwenje kubuda (GAGG-HL) kristaro, kune mutengi mumunda wakasiyana.GAGG: Ce inovimbisa scintillator mune yakakwira simba maindasitiri munda, payaionekwa pakuyedza hupenyu pasi pe115kv, 3mA uye neradiation sosi iri pa150 mm chinhambwe kubva kukristaro, mushure memaawa makumi maviri kuita kwakada kufanana neiyo nyowani. Poshi.Zvinoreva kuti ine tarisiro yakanaka yekumira yakakwira dosi pasi peX-ray irradiation, hongu zvinoenderana nemamiriro eradiation uye kana uchienda mberi neGAGG yeNDT imwe bvunzo chaiyo inofanirwa kuitwa.Padivi peGAGG imwechete: Ce crystal, isu tinokwanisa kuigadzira kuita mutsara uye 2 dimensional array, saizi yepixel uye yekuparadzanisa inogona kuwanikwa zvichienderana nezvinodiwa.Isu takagadzirawo tekinoroji yeceramic GAGG: Ce, ine zvirinani kugadzirisa nguva (CRT), inokurumidza kuora nguva uye yakakwira mwenje kubuda.
Kugadziriswa kwesimba: GAGG Dia2"x2", 8.2% Cs137@662Kev
Afterglow performance
Chiedza chinobuda kushanda
Nguva Yekugadzirisa: Gagg Inokurumidza Kuora Nguva
(a) Kugadzirisa nguva: CRT=193ps (FWHM, hwindo resimba: [440keV 550keV])
(a) Kugadzirisa nguva vs.bias voltage: (hwindo resimba: [440keV 550keV])
Ndokumbira utarise kuti peak emission yeGAGG i520nm nepo maSiPM sensors akagadzirirwa makristasi ane 420nm peak emission.Iyo PDE ye520nm ndeye 30% yakaderera kana ichienzaniswa nePDE ye420nm.Iyo CRT yeGAGG inogona kuvandudzwa kubva pa193ps (FWHM) kuenda pa161.5ps (FWHM) kana PDE yeSiPM sensors ye520nm ichienderana nePDE ye420nm.
