Abstract:

Gamma-ray spectrometers based on lanthanide halide and related scintillators are a very promising class of detectors for nuclear non-proliferation monitoring, providing excellent energy resolution and fast response. However, the growth of large crystals of lanthanide halide scintillators, using traditional melt based processes, has been difficult, due to the physical and chemical properties of lanthanide halides and the limitations imposed by melt-based crystal growth processes. This project will develop technology to grow large crystals of lanthanide halide compositions by a solution growth technique that overcomes many of the problems faced by traditional melt-based approaches. In Phase I, lanthanide halide crystals of size 1 ¿2 cm3 were grown from solution. Their scintillation properties were evaluated, and overall feasibility was demonstrated. Phase II will optimize the solution growth process, including a scale-up of the growth technique. Large crystals of the lanthanide halides and elpasolites (up to 1 ¿2 in3) will be grown from organic solutions. Commercial Applications and other Benefits as described by the awardee: In addition to the application to nuclear non-proliferation monitoring, the materials should find use in detectors used in gamma-ray imaging systems for astronomy, non­destructive studies, and medical imaging
