GAGG:Ce (Gd3Al2Ga3O12) gadolinium aluminika gallium garnet doped me ka cerium.He scintillator hou no ka hoʻokuʻu kiʻi kiʻi kiʻi kiʻi hoʻokahi (SPECT), gamma-ray a me Compton electron detection.ʻO Cerium doped GAGG:Ce nā waiwai he nui i kūpono ia no ka spectroscopy gamma a me nā noi kiʻi lāʻau lapaʻau.ʻO kahi kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe a me ka hoʻokuʻu ʻana ma kahi o 530 nm i kūpono i ka mea e heluhelu ʻia e nā mea ʻike kiʻi hoʻonui Silicon.Ua hoʻomohala ʻo Epic crystal i 3 mau ʻano o GAGG:Ce crystal, me ka kristal manawa pōpopo wikiwiki (GAGG-FD), kristal maʻamau (GAGG-Balance), kristal puka māmā kiʻekiʻe (GAGG-HL), no ka mea kūʻai ma nā kahua like ʻole.GAGG: He scintillator maikaʻi loa ʻo Ce i ke kahua ʻoihana ikehu kiʻekiʻe, i ka wā i hōʻike ʻia ma ka hoʻāʻo ola ma lalo o 115kv, 3mA a me ke kumu radiation aia ma kahi mamao 150 mm mai ke aniani, ma hope o 20 mau hola ua aneane like ka hana me ka mea hou. ʻekahi.ʻO ia ka manaʻo maikaʻi e kū i ka nui ma lalo o ka X-ray irradiation, ʻoiaʻiʻo, pili ia i nā kūlana irradiation a inā e hele hou aku me GAGG no NDT pono e hoʻokō ʻia kahi hoʻokolohua pololei.Ma waho aʻe o ka GAGG hoʻokahi: Ce crystal, hiki iā mākou ke hana i ka laina laina a me 2 dimensional array, hiki ke hoʻokō ʻia ka nui pixel a me ka mea hoʻokaʻawale ma muli o ke koi.Ua hoʻomohala pū mākou i ka ʻenehana no ka ceramic GAGG:Ce, ʻoi aku ka maikaʻi o ka manawa hoʻonā manawa (CRT), ʻoi aku ka wikiwiki o ka manawa palaho a me ka puka māmā.
