Mafotokozedwe Akatundu
LuAG:Ce (Lutetium Aluminium Garnet-Lu3Al5O12:Ce) scintillator makhiristo ndi osalimba (6.73g/cm³), ali ndi Z (63) wapamwamba ndipo amakhala ndi nthawi yovunda mwachangu (70ns).Ndi chiwongola dzanja chapakati cha 530nm, LuAG:Kutulutsa kwa Ce kumagwirizana bwino ndi ma photodiodes avalanche photodiodes APDs ndi silicon photomultipliers (SiPM).Ndi chinthu chopangidwa ndi kristalo chopangidwa ndi cubic chomwe chimagwiritsidwa ntchito ngati scintillation detectors muzinthu zosiyanasiyana zasayansi, monga kujambula kwachipatala ndi kuzindikira kwa radiation.Mukakumana ndi cheza cha ionizing, LuAG:Ce imatulutsa kuwala, komwe kumatha kuzindikirika ndikugwiritsidwa ntchito kupanga zithunzi kapena kuyeza kuchuluka kwa ma radiation.Ili ndi zina zambiri zabwino, monga kachulukidwe kwambiri, Zeff yayikulu komanso makina abwino.LuAG: Kagawo kakang'ono kakang'ono kophatikizana ndi FOP ndi CCD zitha kugwiritsidwa ntchito bwino mu X-ray microscopy ndi micro-nano CT komwe kuyembekezeredwa kusintha kwa malo.Chifukwa cha kachulukidwe kake komanso kuwonekera kwa cheza champhamvu kwambiri, LuAG:Ce ndiyothandiza makamaka pamapulogalamu omwe amafunikira kulondola kwambiri komanso kumva bwino, monga mankhwala a nyukiliya ndi physics yopatsa mphamvu kwambiri.Kuphatikiza apo, LuAG:Ce imadziwika chifukwa cha kuwala kwake kwakukulu, nthawi yowola mwachangu, komanso kuwongolera mphamvu kwamphamvu, zomwe zimapangitsa kuti ikhale chisankho chodziwika bwino kwa zowunikira ma scintillation.Kuphatikiza apo makristalowa ali ndi kutentha kwabwino.
LuAG: Makatani a Ce scintillator ali ndi izi zomwe ziyenera kuzindikirika.Amakhala ndi kuwala komwe mbali yabwino ili pamwamba pa 500nm, dera lomwe ma photomultipliers sakhudzidwa kwambiri.
Amakhala ndi ma radioactive omwe amachititsa kuti zikhale zosavomerezeka kuzinthu zina, komanso kuti zitha kuwonongeka ndi ma radiation, kuyambira ndi mlingo wapakati pa 1 ndi 10 Gray (10² - 10³ rad).Itha kusinthidwa ndi nthawi kapena nthawi.

Chidziwitso Chothandizira
1)Mayeso:Mawonekedwe a kuwala kosonkhezeredwa ndi thermally anayesedwa ndi spectrometer ya Risø TL/OSL-15-B/C.Zitsanzozo zidayatsidwa ndi β-ray (90Sr monga gwero la radiation) kwa 200 s ndi mlingo wa 0.1 Gy/s.Kutentha kwa kutentha kunali 5 ° C / s kuchokera ku 30 mpaka 500 ° C ndipo makulidwe ofanana a zitsanzo adayikidwa kuti atsimikizire kuti zotsatira zake zikufanana.
2)Onetsani:zithunzi zonse zikhoza kusinthidwa;onetsani mawonekedwe a TL akumbuyo, pomwe zitsanzo zotentha kwambiri kuposa 400 ° C mkati mwa 700-800 nm zidatuluka zowala (ma radiation amtundu wakuda);deta yoyambirira idawonjezedwa pazowonjezera.
