BGO Scintillator, Bgo Crystal, Bi4Ge3O12 Scintillator Crystal

inkcazelo emfutshane:

BGO (Bi₄Ge₃O₁₂) zizinto ze-oxide scintillation.Inenombolo ye-athomu ephezulu, ukuxinana okuphezulu, amandla afanelekileyo omatshini, i-non-hygroscopic, akukho cleavage.Ukuxinana okuphezulu kakhulu kwenza le crystal ifaneleke kakhulu ekubhaqweni kwe-radioactivity yendalo.I-BGO inokutshintshwa kwiimilo ezahlukeneyo kunye neejometri.

Ingcaciso yeMveliso

I-BGO (i-bismuth germanate) yikristale ye-scintillation eyenziwe nge-bismuth oxide kunye ne-germanium oxide.Inoxinano oluphezulu kunye nenani eliphezulu leathom, iyenza ilungele ukubona iifotoni zamandla aphezulu.I-BGO scintillators inesisombululo esihle samandla kunye nokukhanya okuphezulu, okubenza babe luncedo ekuboneni imitha ye-gamma kunye nezinye iintlobo zemitha ye-ionizing.

Ezinye izicelo eziqhelekileyo ze-BGO Crystals zibandakanya

1. Iimaging yezonyango: I-BGO scintillators isoloko isetyenziswa kwi-positron emission tomography (PET) scanners ukuze kubonwe imitha ye-gamma ekhutshwa yi-radioisotopes emzimbeni.Banesisombululo esihle kakhulu samandla kunye novelwano xa kuthelekiswa nezinye i-scintillators ezisetyenziswa kwi-PET imaging.

2. Iimvavanyo ze-physics ze-High-energy: Iikristale ze-BGO zisetyenziswa kwiimvavanyo ze-particle physics ukuze zibone iifotoni zamandla aphezulu kwaye, kwezinye iimeko, ii-electron kunye ne-positrons.Ziluncedo ngakumbi ekuboneni imitha ye-gamma kuluhlu lwamandla lwe-1-10 MeV.

3. Ukuhlolwa kokhuseleko: Ii-detectors ze-BGO zihlala zisetyenziswa kwizixhobo zokuhlola ukhuseleko ezifana nemithwalo kunye ne-cargo scanners ukuze zibone ubukho be-radioactive substance.

4. Uphando lwefiziksi yeNyukliya: Iikristale ze-BGO zisetyenziswa kwimifuniselo yefiziksi yenyukliya ukulinganisa i-gamma ray ekhutshwa ziintshukumo zenyukliya.

5. Ukujongwa kwendalo: Izixhobo zokujonga i-BGO zisetyenziswa ekubekeni iliso kokusingqongileyo ukukhangela i-gamma radiation evela kwimithombo yendalo efana namatye, umhlaba, kunye nezixhobo zokwakha.
