Abstract

Cerium-doped Tl2LiYCl6 (TLYC) crystals co-doped with alkaline earth metal ions (Mg2+, Ca2+, Sr2+, Ba2+) are grown using as-received chemicals as ∅16 mm boules using the Bridgman method. Samples processed from each boule are characterized by their scintillation detector properties, such as energy resolution, decay time, and proportionality. More than 12% improvements in light yield are calculated for TLYC co-doped with Mg and Ca. Gamma-neutron pulse shape discrimination using a moderated AmBe neutron source with TLYC crystals co-doped with Mg and Ca result in figure-of-merits of 1.5 and 1.6, respectively.
