Ingcaciso yeMveliso
I-LuAG:Ce (Lutetium Aluminium Garnet-Lu3Al5O12:Ce) iikristale zescintillator zixinene ngokwentelekiso (6.73g/cm³), zine-Z ephezulu (63) kwaye zinexesha lokubola ngokukhawuleza (70ns).Ngencopho yokukhutshwa kweziko le-530nm, iLuAG:Imveliso yeCe ihambelana kakuhle neefotodiodes ze-avalanche photodiodes APDs kunye nesilicon photomultipliers (SiPM).Yimathiriyeli yekristale eyenziweyo enesakhiwo se-cubic esetyenziswa ngokuqhelekileyo njenge-scintillation detectors kwizicelo ezahlukeneyo zesayensi, ezifana nokucinga kwezonyango kunye nokufunyanwa kwemitha.Xa ibekwe kwimitha ye-ionizing, i-LuAG:Ce ikhupha ukukhanya, okunokuthi kubonwe kwaye kusetyenziswe ukwenza imifanekiso okanye ukulinganisa amanqanaba emitha.Inezinye iipropathi ezininzi ezigqwesileyo, ezinje ngoxinaniso oluphezulu, iZeff enkulu kunye nepropathi elungileyo yoomatshini.I-LuAG:Isilayi esibhityileyo esidityaniswe ne-FOP kunye neCCD ingafakwa kakuhle kwi-X-ray microscopy kunye ne-micro-nano CT apho kulindeleke ukuba kulungiswe kakuhle indawo.Ngenxa yoxinaniso oluphezulu kunye nokungafihli kwimitha yemitha ephezulu, iLuAG:Ce iluncedo ngakumbi kwizicelo ezifuna ukuchaneka okuphezulu kunye novakalelo, njengamayeza enyukliya kunye nefiziksi yamandla aphezulu.Ukongeza, i-LuAG:Ce yaziwa ngokuphuma kwayo kokukhanya okuphezulu, ixesha lokubola okukhawulezayo, kunye nesisombululo esibalaseleyo samandla, oko kuyenza ibe lukhetho oludumileyo kwii-scintillation detectors.Ukongeza ezi kristale zineempawu zobushushu ezilungileyo.
I-LuAG:Iikristale ze-Ce scintillator zinemiba elandelayo ekufuneka iqatshelwe.Banokukhutshwa kokukhanya okuyinxalenye elungileyo ingaphezulu kwe-500nm, ummandla apho iifotomultipliers zingenovakalelo kangako.
Ziyi-radioactive eyenzeka ngaphakathi iyenza ingamkeleki kwezinye iinkqubo, kwaye ichaphazeleke kumonakalo wokusasazeka kwemitha, iqala ngeedosi phakathi kwe-1 kunye ne-10 yeGrey (10² - 10³ rad).Inokubuyiselwa emva kwexesha okanye i-anneal.
Uvavanyo lokuSebenza

Ulwazi oluxhasayo
1)Imeko yovavanyo:Umboniso we-luminescence ovuselelwe ngokufudumeleyo ulinganiswe nge-Risø TL/OSL-15-B/C spectrometer.Iisampulu zifakwe kwimitha ye-β-reyi (90Sr njengomthombo wemitha) ye-200 s kunye nesantya se-0.1 Gy / s.Izinga lokufudumeza laliyi-5 °C/s ukusuka kuma-30 ukuya kuma-500 °C kunye nobukhulu obufanayo beesampuli zabekwa ukuqinisekisa ukuba iziphumo ziyathelekiseka.
2)Bonisa:yonke imifanekiso inokuhlelwa;bhekisa kumboniso we-TL wemvelaphi, xa isampulu ishushu ngaphezu kwe-400 °C ngaphakathi kwe-700-800 nm zavela ukukhanya kwesampulu (imitha yomzimba omnyama);idatha yoqobo yongezwa kwi-accessory.
