Improvements in Scintillation Technology for Detection of Nuclear Radiation
Agency / Branch:
DOD / DTRA
OBJECTIVE: Develop innovative scintillator materials for the detection of gamma-ray or neutron radiation for a variety of applications. For handheld and arrayed detectors criteria for improvement include better energy resolution; higher light output (photons per MeV); improved linearity of light output; and smaller, more efficient and more rugged light readout technology to replace photomultiplier tubes and lower power consumption. For applications requiring detectors with very large volume, a low-cost material with significantly better energy resolution is required to replace plastic scintillators. DESCRIPTION: Scintillators that exceed lanthanum halides in brightness with energy resolution approaching the statistical limits for scintillator-based gamma-ray spectrometry are needed for a variety of applications that include handheld detectors and imaging arrays. The goal of this SBIR is to investigate the next-generation scintillators that will exceed the lanthanum halides in brightness (>90,000 photons/MeV) yet have adequate linear response to gamma-ray energies from 60 keV to 3 MeV. These new scintillators should also provide energy resolution of
