[en] Until the discovery of SrI₂:Eu and KSr₂I₅:Eu scintillators in 2008 and 2015 respectively, the best performing scintillator has been LaBr₃:Ce with an excellent resolution of 2.6% and light yield of about 60,000 ph/MeV. The relatively weak (1 0 0) cleavage plane, hexagonal crystal structure with considerable anisotropy in properties like thermal expansion, make the growth of large volume crystals very tricky. With the advancement in technology, it is now possible to design a scintillator for specific purpose. There is a choice for bandgap adjustment and of activator energy levels. Cerium doped Gadolinium gallium aluminium garnet (GGAG:Ce) single crystal scintillator is a consequence of such bandgap engineering resulting from the substitution of Gd and Ga in YAG:Ce, LuAG:Ce single crystals. In the present work, extensive studies on pulse shape discrimination (PSD) and detection efficiency of GGAG:Ce scintillator has been made. Czochralski technique has been employed to grow garnet based single crystal scintillators
