YAP: ʻO Ce scintillator kekahi aniani scintillation doped me nā ion cerium (Ce).Kū ʻo YAP no ka yttrium orthoaluminate co-doped me praseodymium (Pr) a me ka cerium (Ce).YAP: Loaʻa i nā scintillators nā kukui kiʻekiʻe a me ka hoʻonā kino, no laila kūpono lākou no nā hoʻokolohua physics kiʻekiʻe a me nā scans positron emission tomography (PET).

I ka PET scanners, hoʻohana like ka YAP:Ce scintillator me ka LSO:Ce scintillator.Hoʻopili ka YAP:Ce crystal i nā kiʻi i hoʻokuʻu ʻia e ka radiotracer, e hana ana i ke kukui scintillation i ʻike ʻia e kahi pahu photomultiplier (PMT).A laila hoʻololi ka PMT i ka hōʻailona scintillation i ʻikepili kikohoʻe, i hana ʻia e hana i kahi kiʻi o ka hoʻohele radiotracer.

YAP: Ua ʻoi aku ka maikaʻi o nā scintillators Ce ma mua o nā LSO:Ce scintillators ma muli o ko lākou manawa pane wikiwiki, e hoʻomaikaʻi ai i ka hoʻonā kino o nā mea nānā kiʻi PET.Loaʻa iā lākou nā manawa palaho haʻahaʻa, e hōʻemi ana i nā hopena o ke kūkulu ʻana a me ka manawa make i ka uila.Eia nō naʻe, ʻoi aku ka pipiʻi o nā YAP:Ce scintillators i ka hana ʻana a ʻoi aku ka liʻiliʻi ma mua o nā LSO:Ce scintillators, e pili ana i ka hoʻonā kiko o nā mea nānā PET.

YAP: Loaʻa i nā scintillators nā noi he nui ma waho o kā lākou hoʻohana ʻana i nā kiʻi kiʻi PET a me nā hoʻokolohua physics kiʻekiʻe.Aia kekahi o kēia mau noi:

1. Ka ʻike ʻana i ke kukui Gamma: YAP: Hiki i nā scintillators Ce ke ʻike i nā kukuna gamma mai nā kumu like ʻole, me nā reactor nuklea, radioisotopes, a me nā mea lapaʻau.

2. Mākaʻikaʻi ʻana i ka radiation: YAP: Hiki ke hoʻohana ʻia nā scintillators Ce no ka nānā ʻana i nā kiʻekiʻe o ka radiation ma nā mea kanu nuklea a i ʻole nā wahi i hoʻopilikia ʻia e nā ulia nuklea.

3. Laau Nukelea: YAP: Hiki ke hoʻohana ʻia nā scintillators Ce ma ke ʻano he mea ʻike ma nā ʻano kiʻi kiʻi e like me SPECT (Single Photon Emission Computed Tomography), e like me ka PET akā hoʻohana i kahi radiotracer ʻokoʻa.

4. Ka nānā 'ana i ka palekana: YAP: Hiki ke ho'ohana 'ia nā scintillators CE i nā mea nānā 'ike X-ray no ka nānā 'ana i nā ukana, nā pū'olo a i 'ole nā kānaka ma nā mokulele a i 'ole nā wahi palekana ki'eki'e.

5. Astrophysics: YAP:Ce scintillators hiki ke hoʻohana ʻia no ka ʻike ʻana i nā kukuna gamma cosmic i hoʻopuka ʻia e nā kumu astrophysical e like me nā supernovae a i ʻole nā gamma-ray bursts.
