Incazelo Yomkhiqizo
I-BGO (i-bismuth germanate) iyikristalu ye-scintillation eyenziwe nge-bismuth oxide ne-germanium oxide.Inomthamo omkhulu wokuminyana kanye nenombolo ye-athomu ephezulu, okuyenza ifaneleke ukuthola ama-photon anamandla amakhulu.Ama-scintillator e-BGO anokulungiswa okuhle kwamandla kanye nokuphuma kokukhanya okuphezulu, okuwenza abe usizo ekutholeni imisebe ye-gamma nezinye izinhlobo zemisebe ye-ionizing.
Ezinye Izicelo Ezivamile Ze-BGO Crystals Zihlanganisa
1. Isithombe sezokwelapha: Ama-scintillator e-BGO avame ukusetshenziswa kuzikena ze-positron emission tomography (PET) ukuze kutholwe imisebe ye-gamma ekhishwa ama-radioisotopes emzimbeni.Banokulungiswa okuhle kakhulu kwamandla nokuzwela uma kuqhathaniswa namanye ama-scintillator asetshenziswa ku-PET imaging.
2. Ukuhlolwa kwefiziksi yamandla aphezulu: Amakristalu e-BGO asetshenziswa ekuhlolweni kwe-particle physics ukuze kutholwe ama-photon anamandla amakhulu futhi, kwezinye izimo, ama-electron nama-positron.Awusizo ikakhulukazi ekutholeni imisebe ye-gamma ebangeni lamandla le-1-10 MeV.
3. Ukuhlolwa kokuphepha: Izithonjana ze-BGO zivame ukusetshenziswa ezintweni zokuhlola ukuphepha njengezikena zemithwalo nempahla ukuze kutholwe ukuba khona kwezinto ezikhipha imisebe.
4. Ucwaningo lwe-Nuclear physics: Amakristalu e-BGO asetshenziswa ocwaningweni lwe-nuclear physics ukukala i-gamma ray spectrum ekhishwa ukusabela kwenyukliya.
5. Ukuqapha imvelo: Izitholi ze-BGO zisetshenziswa ezinhlelweni zokuqapha imvelo ukuze kutholwe imisebe ye-gamma evela emithonjeni yemvelo njengamatshe, inhlabathi, nezinto zokwakha.
