Summary

Over the past five years, our scintillator materials group has explored many new scintillators for gamma spectroscopy applications. This search and discovery program led us to our current work on the development and commercialization of two materials that offer high resolution gamma spectroscopy: Eu-doped Strontium Iodide single crystals (energy resolution, R = 2.8% at 662 keV), and Ce-doped Gadolinium Garnet transparent ceramics (R = 3.9% at 662 keV with APD readout). The discussions with RIKEN staff and international collaborators will allow us to further specify the relative importance of requirements related to energy resolution, timing, stopping power, radiation hardness, geometry, and mechanical properties, and compare the properties of scintillator materials to identify to most suitable candidate(s) for this application.
