BaF2 Scintillator, BaF2 crystal, BaF2 scintillation crystal

taƙaitaccen bayanin:

BaF2 scintillator yana da kyawawan kaddarorin scintillation da watsawar gani akan kewayon bakan.Ana ɗaukarsa a matsayin mafi sauri scintilators zuwa yanzu.Za'a iya amfani da bangaren mai sauri don auna lokaci daidai da samun ƙudurin lokaci mai kyau, an bi shi azaman scintillator mai ban sha'awa a cikin binciken halakar positron.Yana nuna kyakkyawan taurin radiation har zuwa 10⁶rad ko ma fiye.Lu'ulu'u na BaF2 suna da kyawawan kaddarorin scintillation saboda iyawarsu don fitar da kayan haɗin haske da sauri da jinkirin lokaci guda, suna ba da damar auna kuzarin lokaci guda da bakan lokaci tare da babban ƙarfi da ƙudurin lokaci.Saboda haka, BaF2 yana da aikace-aikace da yawa a fannonin kimiyyar makamashi mai ƙarfi, kimiyyar nukiliya da likitancin nukiliya.
