Abstract
We will present an equipment design and technique to produce inorganic halide ceramic scintillators Cs2HfCl6 (CHC) and Tl2HfCl6 (THC). Also presented is initial ceramic processing for compounds with non-congruent melts: elpasolite Tl2LiLaBr6 (TLLB) and Li-based halide Eu-doped LiSr2I5 (LSI). Comparison between the crystal results from the melt growth method and the ceramic fabrication will be presented. Improvements and optimization of CHC and THC ceramic scintillator fabrication are gauged by monitoring the energy resolution and peak position of 137Cs full energy peak at 662 keV. Both ceramic CHC and THC scintillators have similarly good proportionality compared to their single crystal counterparts.
