Tlhaloso ea Sehlahisoa
LuAG:Ce (Lutetium Aluminium Garnet-Lu3Al5O12:Ce) likristale tsa scintillator li batla li le boima (6.73g/cm³), li na le Z (63) tse phahameng 'me li na le nako ea ho bola ka potlako (70ns).Ka tlhahiso ea tlhōrō e bohareng ea 530nm, LuAG: Ce output e tsamaisana hantle le photodiodes avalanche photodiodes APDs le silicon photomultipliers (SiPM).Ke thepa ea maiketsetso ea kristale e nang le sebopeho sa cubic se sebelisoang hangata joalo ka lisebelisoa tsa scintillation lits'ebetsong tse fapaneng tsa mahlale, joalo ka litšoantšo tsa bongaka le ho lemoha mahlaseli.Ha e pepeselitsoe mahlaseli a ionizing, LuAG:Ce e ntša leseli, le ka bonoang le ho sebelisoa ho etsa litšoantšo kapa ho lekanya maemo a mahlaseli.E na le lintho tse ling tse ngata tse ntle haholo, joalo ka bongata bo phahameng, Zeff e kholo le thepa e ntle ea mochini.LuAG: Selae se tšesaane se kopantsoeng le FOP le CCD se ka sebelisoa hantle ka har'a microscopy ea X-ray le micro-nano CT moo ho lebelletsoeng qeto e ntle ea sebaka.Ka lebaka la ho teteana ha eona ho phahameng le ho pepeseha mahlaseling a matla a phahameng, LuAG:Ce e thusa haholo lits'ebetsong tse hlokang ho nepahala le kutloisiso e phahameng, joalo ka meriana ea nyutlelie le fisiks e matla haholo.Ho feta moo, LuAG:Ce e tsebahala ka khanya ea eona e phahameng, nako ea ho bola ka potlako, le tharollo e ntle ea matla, e leng se etsang hore e be khetho e tsebahalang bakeng sa lisebelisoa tsa scintillation.Ho feta moo likristale tsena li na le thepa e ntle ea mocheso.
