Research Institution
Gamma-ray spectrometers based on lanthanide halide scintillators are a very promising class of detectors for nuclear nonproliferation monitoring. They provide 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 physical and chemical properties of lanthanide halides and the limitations imposed by the melt based crystal growth processes. This project will investigate a new approach for growing large crystals of lanthanide halide compositions that overcomes many of the problems faced by traditional melt-based growth approaches. Phase I will demonstrate the feasibility of the proposed approach. Optimization and scale-up of the new growth process is planned for Phase II. Commercial Applications and other Benefits as described by the awardee: The proposed detector technology should be very promising for nuclear nonproliferation monitoring. It also should be applicable to other gamma-ray imaging systems in astronomy, non-destructive evaluation, and medical imaging.
