YAP:Ce scintillator jẹ okuta scintillation miiran ti a ṣe pẹlu cerium (Ce) ions.YAP duro fun yttrium orthoaluminate àjọ-doped pẹlu praseodymium (Pr) ati cerium (Ce).YAP:Ce scintilators ni iṣelọpọ ina giga ati ipinnu igba diẹ, ṣiṣe wọn dara fun awọn adanwo fisiksi agbara-giga bi daradara bi awọn ọlọjẹ positron emission tomography (PET).
Ninu awọn aṣayẹwo PET, YAP:Ce scintillator ti wa ni lilo bakanna si LSO:Ce scintillator.YAP:Ce kristali n gba awọn photon ti o jade nipasẹ radiotracer, ti o nmu ina scintillation ti o rii nipasẹ tube fọtomultiplier (PMT).PMT lẹhinna ṣe iyipada ifihan agbara scintillation sinu data oni-nọmba, eyiti a ṣe ilana lati ṣe agbekalẹ aworan ti pinpin redio.
YAP:Ce scintilators jẹ ayanfẹ ju LSO:Ce scintilators nitori akoko idahun yiyara wọn, eyiti o ṣe ilọsiwaju ipinnu igba diẹ ti awọn ọlọjẹ PET.Wọn tun ni awọn iwọn akoko ibajẹ kekere, idinku awọn ipa ti iṣelọpọ ati akoko ti o ku ninu ẹrọ itanna.Sibẹsibẹ, YAP:Ce scintilators jẹ gbowolori diẹ sii lati gbejade ati iwuwo kere ju LSO:Ce scintilators, eyiti o ni ipa lori ipinnu aye ti awọn ọlọjẹ PET.
YAP:Ce scintilators ni awọn ohun elo lọpọlọpọ yatọ si lilo wọn ni awọn ọlọjẹ PET ati awọn adanwo fisiksi agbara giga.Diẹ ninu awọn ohun elo wọnyi pẹlu:
1. Ṣiṣawari Gamma-ray: YAP:Ce scintilators le ṣe awari gamma-rays lati awọn orisun oriṣiriṣi, pẹlu awọn reactors iparun, radioisotopes, ati awọn ohun elo iṣoogun.
2. Abojuto Radiation: YAP:Ce scintilators le ṣee lo lati ṣe atẹle awọn ipele itọsi ni awọn ile-iṣẹ agbara iparun tabi awọn agbegbe ti o kan nipasẹ awọn ijamba iparun.
3. Oogun iparun: YAP:Ce scintilators le ṣee lo bi awọn aṣawari ni awọn ọna aworan bii SPECT (Single Photon Emission Computed Tomography), eyiti o jọra si PET ṣugbọn nlo ẹrọ redio ti o yatọ.
4. Aabo Antivirus: YAP:Ce scintilators le ṣee lo ni X-ray scanners fun aabo waworan ti ẹru, jo tabi eniyan ni papa tabi awọn miiran ga aabo agbegbe.
5. Astrophysics: YAP:Ce scintilators le ṣee lo lati ṣe awari awọn egungun gamma agba aye ti o jade nipasẹ awọn orisun astrophysical gẹgẹbi supernovae tabi gamma-ray bursts.
