We built a test stand in order to measure novel scintillator materials’ decay lifetimes. Radiography and imaging are valuable diagnostic tools for studying dynamic experiments, thus new scintillator materials are needed to improve the resolution of the current observational systems. A collaborative effort by the neutron imaging and x-ray radiography teams is underway to study the novel scintillator materials developed at Los Alamos National Laboratory (LANL) and by outside collaborators. Decay lifetimes and spectra are important characteristics of a scintillator material. By developing this test stand we have provided an avenue to further scintillator development. We confirm the effectiveness of this test stand by comparing known scintillator decay lifetimes of LYSO and polystyrene samples. In an upgraded implementation of the developed test stand, mixed garnet samples are characterized. Development, design, and results of the initial test stand as well as the garnet characterizations will be presented.
