We perform an investigation into the scintillation processes and performance of elpasolites Cs₂LiLaBr_6-xCl_x:Ce (CLLBC) and Cs₂LiYBr₆:Ce (CLYB) using a thermal cycle over a range of -20 to +50º C. At 10º increments, we acquire data with both a waveform digitizer and charge-integrating electronics. We identify decay components and evaluate decay times, thermal neutron gamma-equivalent energy (GEE), and pulse shape discrimination (PSD) performance. Results are compared to common Cs₂LiYCl₆:Ce (CLYC).
