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

Kufotokozera mwachidule:

YAP: Ce ndi kristalo wofulumira wa scintillation wokhala ndi mphamvu zamakina abwino komanso katundu wosamva mankhwala.Mphamvu zamakina zapamwamba zimathandizira kukonza bwino, mazenera olowera amatha kupangidwa ndi wosanjikiza wochepa kwambiri wa aluminiyumu woyikidwa pamwamba pa kristalo.

Chiyambi cha Zamalonda

YAP: Ce scintillator ndi kristalo wina wa scintillation wokhala ndi ayoni a cerium (Ce).YAP imayimira yttrium orthoaluminate co-doped ndi praseodymium (Pr) ndi cerium (Ce).YAP: Ma scintillator a Ce scintillator amakhala ndi kuwala kwakukulu komanso kusintha kwakanthawi, zomwe zimawapangitsa kukhala oyenera kuyeserera kwamagetsi amphamvu kwambiri komanso ma scanner a positron emission tomography (PET).

Mu PET scanner, YAP:Ce scintillator imagwiritsidwa ntchito mofanana ndi LSO:Ce scintillator.The YAP: Ce crystal imatenga zithunzithunzi zotulutsidwa ndi radiotracer, kutulutsa kuwala kwa scintillation komwe kumadziwika ndi chubu cha photomultiplier (PMT).PMT ndiye amasintha chizindikiro cha scintillation kukhala deta ya digito, yomwe imakonzedwa kuti ipange chithunzi cha kugawa kwa radiotracer.

YAP: Ce scintillators amakondedwa kuposa LSO:Ce scintillators chifukwa chanthawi yoyankhira mwachangu, zomwe zimathandizira kusanja kwakanthawi kwa PET scanner.Amakhalanso ndi nthawi zowola zochepa, kuchepetsa zotsatira za kumangidwa ndi nthawi yakufa mumagetsi.Komabe, ma scintillator a YAP:Ce ndi okwera mtengo kwambiri kupanga komanso ocheperako kuposa LSO:Ce scintillators, omwe amakhudza kusintha kwa malo kwa PET scanner.

YAP: Ce scintillators ali ndi ntchito zingapo kuphatikiza kugwiritsa ntchito makina ojambulira a PET komanso kuyesa kwamphamvu kwafizikiki.Ena mwa mapulogalamuwa ndi awa:

1. Kuzindikira kwa gamma-ray: YAP: Ma scintillator a Ce amatha kuzindikira ma gamma-ray kuchokera kuzinthu zosiyanasiyana, kuphatikiza zida za nyukiliya, ma radioisotopes, ndi zida zamankhwala.

2. Kuyang'anira ma radiation: YAP: Ma scintillator a Ce scintillator atha kugwiritsidwa ntchito kuyang'anira kuchuluka kwa ma radiation m'mafakitale opangira magetsi a nyukiliya kapena madera omwe akhudzidwa ndi ngozi zanyukiliya.

3. Mankhwala a nyukiliya: YAP: Ce scintillators angagwiritsidwe ntchito ngati zowunikira mu njira zojambula zithunzi monga SPECT (Single Photon Emission Computed Tomography), yomwe ili yofanana ndi PET koma imagwiritsa ntchito radiotracer yosiyana.

4. Kusanthula kwachitetezo: YAP: Ma scintillator a Ce scintillator atha kugwiritsidwa ntchito mu makina a X-ray powunika chitetezo cha katundu, mapaketi kapena anthu omwe ali pabwalo la ndege kapena malo ena otetezedwa kwambiri.

5. Astrophysics: YAP: Ma scintillator a Ce scintillator amatha kugwiritsidwa ntchito kuzindikira kuwala kwa cosmic gamma komwe kumatulutsidwa ndi zinthu zakuthambo monga supernovae kapena gamma-ray bursts.
