Nuxurka Iftiimin - Goynta-Dhaafka LSO(Ce) Crystal ee Dareenka Spectral La Wanaajiyey

Nuxurka Iftiimin - Goynta-Qaybta LSO(Ce) Crystal ee La Wanaajiyey Dareenka Muuqaalka Sawirka

Sharaxaad Gaaban:

Soo bandhigida "Nuxurka Iftiimay," wax soo saarka gees-goynta leh oo muujinaya tignoolajiyada LSO(Ce). Loogu talagalay in lagu beddelo dareenka muuqaalka, wuxuu bixiyaa waxqabad aan isbarbardhigin guud ahaan sawirka caafimaadka, cilmi-baarista fiisigiska nukliyeerka, iyo codsiyada amniga dalka. Iyada oo loo marayo injineernimo xeel dheer iyo wax soo saar horumarsan, waxay soo saartaa iftiin gaar ah iyo awoodo ogaansho sax ah, dejinta heerar cusub oo ku saabsan hal-abuurnimada walxaha scintillation. Alaabtayadu waxay muujinaysaa sifooyinka gaarka ah iyo codsiyada la taaban karo, muujinta awoodda ay u leedahay in ay kaxeyso horumarka dhinacyada kala duwan ee ku xiran tignoolajiyada wax-qabadka sare leh.

Soo bandhigida sanduuqa waferka

Kariskeena LSO(Ce) wuxuu matalaa meesha ugu saraysa ee tignoolajiyada wax-soo-saarka, taasoo bixisa waxqabad aan caadi ahayn oo codsiyo kala duwan ah. Iyada oo lagu farsameeyay saxnaanta iyo khibradda, crystal-kan waxa lagu daraa cerium (Ce) si kor loogu qaado waxtarkeeda wax soo saarka iftiinka iyo jawaabta muuqaalka.

Crystal LSO(Ce) waxay ku faantaa xalinta tamarta sare iyo sifooyinka wakhtiga, taas oo ka dhigaysa doorasho ku habboon sawir qaadista positron spectroscopy (PET), spectroscopy gamma-ray, iyo codsiyada kale ee sawir-caafimaad iyo ogaanshaha shucaaca. Dhalinteeda iftiinka sare iyo wakhtiga qudhunka degdega ah waxay hubisaa in si sax ah oo la isku halayn karo loo ogaado fallaadhaha gamma iyo shucaaca kale ee ionizing.

Iyada oo leh waxqabadkeeda iyo isku halaynta wanaagsan, LSO(Ce) crystal-ka ayaa dejisa halbeeg cusub oo agabka wax lagu sawiro, awood u siinaya horumarinta cilmi-baarista sayniska, ogaanshaha caafimaadka, iyo amniga dalka. Khibrad u yeelo dareenka iyo saxnaanta aan la barbar dhigi karin ee LSO(Ce) crystal, wadista hal-abuurka iyo daahfurka dhinacyo kala duwan.
