Whakaahuatanga Hua
GAGG:Ce (Gd3Al2Ga3O12) gadolinium konumohe gallium kareti kua pania ki te cerium.He scintillator hou mo te whakamaarama irahiko kotahi te tukunga whakaahua (SPECT), hihi-gamma me te rapunga irahiko Compton.Cerium doped GAGG: He maha nga taonga a Ce e pai ana mo te hihinga o te gamma me nga tono atahanga rongoa.Ko te nui o te whakaputanga whakaahua me te teitei o te tukunga huri noa i te 530 nm e pai ana te rauemi kia panuihia e nga kaitirotiro whakarea-whakaahua a Silicon.Ko te karaihe hautoa i whakawhanakehia e 3 nga momo GAGG:Ce tioata, he tere ake te wa pirau(GAGG-FD) karaihe, he karaihe angamaheni (GAGG-Balance), he maramara teitei ake (GAGG-HL) karaihe, mo te kaihoko i nga mara rereke.GAGG:Ce he scintillator tino whaihua i roto i te mara ahumahi kaha nui, i te wa e whakaatuhia ana i runga i te whakamatautau ora i raro i te 115kv, 3mA me te puna radiation kei te 150 mm te tawhiti mai i te karaihe, i muri i nga haora 20 he rite tonu te mahi ki te hou. kotahi.Ko te tikanga he pai te tumanako ki te tu atu i te horopeta teitei i raro i te whakamaarama hihi-X, o te tikanga ka whakawhirinaki ki nga tikanga whakamaarama me te haere tonu me te GAGG mo te NDT me whakahaere ano he whakamatautau tika.I te taha o te karaihe GAGG:Ce kotahi, ka taea e matou te hanga ki roto i te rarangi raina me te 2 ahu, te rahi pika me te wehewehe ka taea te whakatutuki i runga i te hiahia.Kua whakawhanakehia hoki e matou te hangarau mo te GAGG uku:Ce, he pai ake te waa whakatau (CRT), he tere ake te wa pirau me te putanga marama ake.
Taumira pūngao: GAGG Dia2”x2”, 8.2% Cs137@662Kev
Te mahi o muri
Maama te mahi whakaputa
Wā Whakatau: Gagg Tere Te Waa pirau
(a) Taumira wa: CRT=193ps (FWHM, matapihi hiko: [440keV 550keV])
(a) Wā whakataunga vs.ngaohiko rītaha: (matapihi pūngao: [440keV 550keV])
Kia mahara ko te teitei o te tukunga o GAGG he 520nm i te wa e hangaia ana nga pūoko SiPM mo nga tioata me te 420nm teitei o te whakaputanga.Ko te PDE mo te 520nm he 30% te iti ake ki te PDE mo te 420nm.Ka taea te whakapai ake i te CRT o GAGG mai i te 193ps (FWHM) ki te 161.5ps (FWHM) mena ka rite te PDE o nga puoro SiPM mo te 520nm me te PDE mo te 420nm.
