LuAG:Ce (Lutetium Aluminum Garnet-Lu3Al5O12:Ce) scintillator crystals he ma'amau (6.73g/cm³), loa'a ka Z ki'eki'e (63) a loa'a ka manawa pohō wikiwiki (70ns).Me ka hoʻokuʻu ʻana o ka piko waena o 530nm, ua hoʻohālikelike pono ʻia ka puka ʻana o LuAG:Ce me nā photodiodes avalanche photodiodes APDs a me nā mea hoʻonui kiʻi silicon (SiPM).ʻO ia kahi mea crystalline synthetic me kahi ʻano cubic i hoʻohana mau ʻia e like me nā mea ʻike scintillation i nā noi ʻepekema like ʻole, e like me ke kiʻi lāʻau lapaʻau a me ka ʻike radiation.Ke hōʻike ʻia i ka radiation ionizing, LuAG:Ce e hoʻopuka i ke kukui, hiki ke ʻike ʻia a hoʻohana ʻia e hana i nā kiʻi a i ʻole ke ana ʻana i nā pae radiation.Loaʻa iā ia nā waiwai maikaʻi ʻē aʻe, e like me ke kiʻekiʻe kiʻekiʻe, Zeff nui a me ka waiwai mechanical maikaʻi.LuAG: Hiki ke hoʻohana maikaʻi ʻia ka ʻāpana lahilahi Ce i hui pū ʻia me FOP a me CCD i ka microscopy X-ray a me ka micro-nano CT kahi e manaʻo ʻia ai ka hoʻonā spatial maikaʻi.Ma muli o kona kiʻekiʻe kiʻekiʻe a me ka ʻike ʻole i ka pāhawewe ikehu kiʻekiʻe, ʻoi aku ka maikaʻi o ka LuAG:Ce i nā noi e koi ana i ka pololei kiʻekiʻe a me ka naʻau, e like me ka lāʻau nuklea a me ka physics kiʻekiʻe.Hoʻohui ʻia, ʻike ʻia ʻo LuAG:Ce no kāna puka kukui kiʻekiʻe, ka manawa palaho wikiwiki, a me ka hoʻonā ʻana o ka ikehu maikaʻi loa, e lilo ia i koho kaulana no nā mea ʻike scintillation.Eia kekahi, loaʻa i kēia mau kristal nā waiwai wela maikaʻi.
LuAG: Loaʻa i nā kristal scintillator Ce nā pilikia e pono e hoʻomaopopo ʻia.Loaʻa iā lākou kahi hoʻokuʻu māmā a ʻoi aku ka maikaʻi ma luna o 500nm, kahi ʻāina kahi i emi ʻole ai ka naʻau o nā photomultipliers.
He radioactive maoli lākou no ka ʻae ʻole ʻia no kekahi mau noi, a hiki ke hoʻopōʻino i ka radiation, e hoʻomaka ana me ka nui ma waena o 1 a me 10 Gray (10² - 10³ rad).Hiki ke hoʻohuli ʻia me ka manawa a i ʻole annealing.
