Abstract
Transparent ceramic Cerium-doped Gadolinium Yttrium Gallium Aluminum Garnet, GYGAG(Ce), offers a combination of environmental stability, high light yield, good gamma spectroscopy and formability into large plates that is attractive for implementation into Radiation Portal Monitors. GYGAG(Ce) plates at 4” x 4” x 0.5” scale achieve energy resolution of R(662 keV) <7%. Production of high transparency 8 in3 GYGAG(Ce) plates is underway, as well as their integration into detector modules and portal systems.
