I-Bi4Si3O12 scintillator, ikristale ye-BSO, ikristale ye-BSO scintillation

inkcazelo emfutshane:

Bi₄(SiO₄)₃(BSO) luhlobo olutsha lwe-crystal ye-scintillation kunye nokusebenza kakuhle, inomatshini omhle kunye nokuzinza kweekhemikhali, i-photoelectric kunye neempawu zokukhululwa kwe-thermal.Ikristale ye-BSO ineempawu ezininzi ezifana ne-BGO, ngakumbi kwezinye izikhombisi eziphambili ezifana ne-afterglow kunye ne-attenuation rhoqo, kwaye inokusebenza okungcono.Kwiminyaka yakutshanje, iye yatsala ingqalelo yabaphandi benzululwazi.Ke inoluhlu olubanzi lwezicelo kwifiziksi yamandla aphezulu, amayeza enyukliya, isayensi yendawo, ukubonwa kweGamma, njl.

Ingcaciso yeMveliso

I-Bi4 (SiO4)3 (BSO) yi-scintillator ye-inorganic, i-BSO yaziwa ngokuxinana kwayo okuphezulu, nto leyo eyenza ukuba ibe yinto esebenzayo yokufunxa imitha ye-gamma, efunxa amandla kwimitha ye-ionizing kwaye ikhuphe iifotoni zokukhanya ezibonakalayo ekuphenduleni.Oko kuyenza ibe sisixhobo esibuthathaka semitha ye-ionizing.Isetyenziswa ngokuqhelekileyo kwizicelo zokubona ukukhanya kwemitha.I-BSO scintillators inobulukhuni obuhle be-radiation kunye nokuchasana nomonakalo we-radiation, ibenza babe yinxalenye yee-detectors ezithembekileyo zokusetyenziswa kwexesha elide.Okufana ne-BSO esetyenziswa kwiimonitha ze-radiation portal ukubona imathiriyeli ye-radioactive kwimpahla kunye nezithuthi kwiindawo zokuwela imida kunye nezikhululo zeenqwelomoya.

Ubume bekristale be-BSO scintillators buvumela ukuphuma kokukhanya okuphezulu kunye namaxesha okuphendula ngokukhawuleza, oko kubenza balungele iimvavanyo zefiziksi yamandla aphezulu kunye nezixhobo zokucinga zonyango, ezifana ne-PET (Positron Emission Tomography) scanners, kunye ne-BSO inokusetyenziselwa ukukhangela izixhobo zenyukliya. amanqanaba emitha kunye nokubeka esweni ukusebenza kwe-reactor.Iikristale ze-BSO zinokukhuliswa kusetyenziswa indlela yeCzochralski kwaye zibunjwe zibe ziimo ezahlukeneyo ngokuxhomekeke kwisicelo.Zihlala zisetyenziswa ngokubambisana ne-photomultiplier tubes (PMTs).
