Khoom Taw Qhia
Scintillators nrog lub teeb pom kev zoo tuaj yeem hloov pauv feem ntau ntawm cov hluav taws xob nqus hluav taws xob rau hauv cov duab pom tau.Qhov no ua rau muaj kev nkag siab ntau dua ntawm kev tshawb pom hluav taws xob, tso cai rau kev tshawb pom ntawm cov hluav taws xob qis lossis luv dua lub sij hawm raug.
Lub monoclinic scintillator yog cov khoom siv scintillator nrog cov qauv siv lead ua monoclinic.Scintillators yog cov ntaub ntawv uas tawm lub teeb thaum lawv nqus cov hluav taws xob ionizing, xws li X-rays lossis gamma rays.Lub teeb emission no, hu ua scintillation, tuaj yeem kuaj pom thiab ntsuas nrog lub photodetector xws li lub raj photomultiplier lossis lub ntsuas hluav taws xob.
Cov qauv siv lead ua monoclinic yog hais txog qhov tshwj xeeb ntawm cov atoms lossis molecules nyob rau hauv ib lub lattice siv lead ua.Nyob rau hauv cov ntaub ntawv ntawm monoclinic scintillators, lub atoms los yog molecules yog teem nyob rau hauv ib tug tilted los yog tilted yam, uas ua rau ib tug yam ntxwv siv lead ua qauv nrog ib tug tshwj xeeb lub cev thiab tshuaj.Cov qauv siv lead ua monoclinic tuaj yeem sib txawv nyob ntawm cov khoom siv scintillator, uas tuaj yeem suav nrog cov organic lossis inorganic compounds.
Cov monoclinic scintillators sib txawv yuav muaj cov khoom sib txawv, xws li emission wavelength, lub teeb tso zis, lub sij hawm yam ntxwv, thiab hluav taws xob rhiab heev.Monoclinic scintillators tau dav siv hauv kev kho mob, kuaj pom hluav taws xob thiab ntsuas, kev nyab xeeb hauv tebchaws, nuclear physics, thiab lub zog siab physics, ntawm qhov kev tshawb nrhiav thiab ntsuas ntawm ionizing hluav taws xob tseem ceeb heev.
