Abstract :
We are developing new scintillator materials that offer potential for high resolution gamma ray spectroscopy at low cost. Single crystal SrI2(Eu) offers ~3% resolution at 662 keV, in sizes of ~1 in3. We have developed ceramics processing technology allowing us to achieve cubic inch scale transparent ceramic scintillators offering gamma spectroscopy performance superior to NaI(Tl). Our bismuth-loaded plastic scintillator demonstrates energy resolution of ~8% at 662 keV, for samples of ~0.5 cm3.
