YAP:Ce Scintillator, Yap Ce Crystal, YAp:Ce Scintillation crystal

incazelo emfushane:

I-YAP: I-Ce iyikristalu esheshayo ye-scintillation enamandla umakhenikha amahle kanye nempahla ekwazi ukumelana namakhemikhali.Amandla aphezulu emishini anika amandla ukukhanda okunembayo, amafasitela okungena angenziwa ngongqimba oluncane lwe-aluminium olubekwe phezu kwekristalu.

Isingeniso Somkhiqizo

I-YAP:I-Ce scintillator enye ikristalu ye-scintillation ehlanganiswe nama-ion e-cerium (Ce).I-YAP imele i-yttrium orthoaluminate co-doped ne-praseodymium (Pr) kanye ne-cerium (Ce).I-YAP:Ama-Ce scintillator anokukhanya okuphezulu okukhiphayo nokulungiswa kwesikhashana, okuwenza afanelekele ukuhlolwa kwe-physics yamandla aphezulu kanye nezikena ze-positron emission tomography (PET).

Kuma-PET scanners, i-YAP:Ce scintillator isetshenziswa ngokufanayo ne-LSO:Ce scintillator.I-YAP:Ce crystal imunca ama-photon akhishwa i-radiotracer, ikhiqize ukukhanya kwe-scintillation okutholwa ngeshubhu le-photomultiplier (PMT).I-PMT ibe isiguqula isignali ye-scintillation ibe idatha yedijithali, ecutshungulwa ukuze kukhiqizwe isithombe sokusatshalaliswa kwe-radiotracer.

I-YAP:Ama-Ce scintillator akhethwa kune-LSO:Ce scintillator ngenxa yesikhathi sawo sokuphendula esisheshayo, esithuthukisa ukulungiswa kwesikhashana kwezikena ze-PET.Futhi banezikhathi zokubola eziphansi, ezinciphisa imiphumela ye-buildup kanye nesikhathi esifile kuma-electronics.Nokho, ama-YAP:Ce scintillator abiza kakhulu ukukhiqiza futhi aminyene kancane kune-LSO:Ce scintillators, athinta ukulungiswa kwendawo yezikena ze-PET.

I-YAP: Ama-Ce scintillator anezinhlelo zokusebenza eziningi ngaphandle kokusebenzisa izikena ze-PET kanye nokuhlolwa kwe-physics yamandla aphezulu.Ezinye zalezi zicelo zihlanganisa:

1. Ukutholwa kwe-Gamma-ray: YAP:Ama-Ce scintillator angathola imisebe ye-gamma emithonjeni ehlukahlukene, okuhlanganisa ama-reactors enuzi, ama-radioisotopes, nezisetshenziswa zezokwelapha.

2. Ukuqapha imisebe: YAP: Ama-Ce scintillator angasetshenziswa ukuqapha amazinga emisebe ezikhungweni zokuphehla amandla enuzi noma ezindaweni ezithintwe izingozi zenuzi.

3. Umuthi wenuzi: YAP:Ama-Ce scintillator angasetshenziswa njengezitholi ezindleleni zokuthatha izithombe ezifana ne-SPECT (I-Single Photon Emission Computed Tomography), efana ne-PET kodwa esebenzisa i-radiotracer ehlukile.

4. Ukuskena kwezokuphepha: YAP: Ama-Ce scintillator angasetshenziswa kuma-X-ray scanner ukuze kuhlolwe ukuphepha kwemithwalo, amaphakheji noma abantu ezikhumulweni zezindiza noma kwezinye izindawo zokuphepha okuphezulu.

5. I-Astrophysics: YAP:Ama-Ce scintillator angasetshenziswa ukuthola imisebe ye-gamma ye-cosmic ekhishwa imithombo ye-astrophysical efana ne-supernovae noma ukuqhuma kwe-gamma-ray.
