Ibisobanuro ku bicuruzwa
Kurongora tungstate (PbWO₄ / PWO) ni kristu ya scintillation ikunze gukoreshwa mubushakashatsi bwa fiziki yingufu nyinshi ndetse no mubushakashatsi bwerekana amashusho nka PET (positron emission tomografiya) na scaneri ya CT (computing tomografiya).Imwe mu miterere yingenzi ya PWO, ifite ubucucike bukabije, butuma PWO yakira imirasire ya gamma neza kurusha izindi kristu ya scintillation.Na none, ibi bivamo ibimenyetso byinshi byerekana-urusaku no gukemura neza imirasire.Kirisiti ebyiri nazo zizwiho igihe cyihuta cyo gusubiza, bigatuma zikwiranye na sisitemu yo kubona amakuru yihuse.
Zirwanya kandi kwangirika kwimirase hamwe nigihe kirekire gihamye, bigatuma bahitamo kwizerwa kubidukikije bikabije.Nyamara, urumuri ruciriritse rusohoka rwa kristu ya PWO ugereranije nibindi bikoresho bya scintillation bigabanya ibyiyumvo byabo mubikorwa bimwe.Crystal isanzwe ikura hakoreshejwe uburyo bwa Czochralski kandi irashobora kubumbabumbwa muburyo butandukanye bitewe nibisabwa.PWO scintillator kristal ifite ibibazo bikurikira bigomba kwitonderwa: PWO ifite urumuri ruto rusohoka.Zifite amaradiyo akora kuburyo butemewe kubisabwa bimwe.Bashobora kwangirika kwimirase.StarTting hamwe na dosiye iri hagati ya 1 na 10 Icyatsi (10² - 10³ rad).Kandi guhindurwa nigihe cyangwa annealing.
