Khoom Taw Qhia
YAP: Ce scintillator yog lwm qhov siv lead ua ci ci doped nrog cerium (Ce) ions.YAP stands rau yttrium orthoaluminate co-doped nrog praseodymium (Pr) thiab cerium (Ce).YAP: Ce scintillators muaj lub teeb pom kev zoo thiab kev daws teeb meem ntawm lub cev, ua rau lawv tsim nyog rau kev sim siab lub zog physics nrog rau positron emission tomography (PET) scanners.
Hauv PET scanners, YAP:Ce scintillator yog siv zoo ib yam li LSO:Ce scintillator.Lub YAP: Ce siv lead ua absorbs photons tawm los ntawm radiotracer, tsim lub teeb pom kev zoo uas pom los ntawm lub raj photomultiplier (PMT).Lub PMT tom qab ntawd hloov cov teeb liab scintillation rau hauv cov ntaub ntawv digital, uas tau ua tiav los tsim cov duab ntawm cov xov tooj cua xa xov tooj cua.
YAP: Ce scintillators nyiam dua LSO: Ce scintillators vim lawv lub sijhawm teb sai dua, uas txhim kho lub cev kev daws teeb meem ntawm PET scanners.Lawv kuj muaj lub sij hawm lwj tsis tu ncua, txo cov teebmeem ntawm buildup thiab tuag lub sij hawm nyob rau hauv electronics.Txawm li cas los xij, YAP: Ce scintillators kim dua los tsim thiab tsawg dua li LSO: Ce scintillators, uas cuam tshuam rau qhov kev daws teeb meem ntawm PET scanners.
YAP: Ce scintillators muaj ntau daim ntawv thov ntxiv rau lawv siv hauv PET scanners thiab kev sim lub zog physics.Qee qhov kev thov no suav nrog:
1. Kev kuaj pom gamma-ray: YAP: Ce scintillators tuaj yeem ntes gamma-rays los ntawm ntau qhov chaw, suav nrog nuclear reactors, radioisotopes, thiab cov khoom siv kho mob.
2. Kev saib xyuas hluav taws xob: YAP: Ce scintillators tuaj yeem siv los saib xyuas cov hluav taws xob hluav taws xob hauv cov chaw tsim hluav taws xob nuclear lossis thaj chaw cuam tshuam los ntawm kev sib tsoo nuclear.
3. Cov tshuaj Nuclear: YAP: Ce scintillators tuaj yeem siv los ua cov khoom siv hauv cov duab xws li SPECT (Single Photon Emission Computed Tomography), uas zoo ib yam li PET tab sis siv cov xov tooj cua sib txawv.
4. Kev soj ntsuam kev ruaj ntseg: YAP: Ce scintillators tuaj yeem siv hauv X-ray scanners rau kev soj ntsuam kev ruaj ntseg ntawm lub nra, pob khoom lossis cov neeg hauv tshav dav hlau lossis lwm qhov chaw ruaj ntseg siab.
5. Astrophysics: YAP: Ce scintillators tuaj yeem siv los ntes cosmic gamma rays tawm los ntawm astrophysical qhov chaw xws li supernovae lossis gamma-ray tawg.
