Title: Gamma-ray spectroscopic characterization of long, rapidly-grown KSr2I5:Eu crystals

Abstract

Collimation and volumetric studies were done to evaluate the gamma-ray spectroscopic performance of KSr2I5:Eu scintillators grown via the vertical Bridgman method. To demonstrate practical crystal growth for large-scale production, Ø1 in. × 6 in. long crystals were grown using fast pulling rates up to 5 mm/h and short cooling times. The long crystals were sectioned into shorter Ø1 in. cylinders to investigate sample-to-sample variation of scintillation properties, the effects of self-absorption and scintillation non-uniformity using different gamma-ray excitation configurations. The best light output and energy resolution achieved for the largest volume and aspect ratio crystals (60 cm3 Ø1 in x 4.7 in. long) were 53,500 ph/MeV and 4.6% at 662 keV. Finally, we produced eight Ø1 in. × 1 in. (12.5 cm3) cylindrical samples, four from each boule, with energy resolutions between 3.1%-3.5% at 662 keV.
