- abstract
- To address outstanding issues in the growth and performance of crystals for radiation detection, I develop and employ several material characterization techniques not previously implemented in the field. Two main, interconnected issues are addressed: the cracking of certain crystals during the growth process and spatial inhomogeneity in the defect distributions of radiation detector crystals. Although the purpose of these materials is to detect high-energy gamma rays, no gamma rays were used in these studies. Instead, much can be learned from the more precise interactions of low-energy photon and neutron beams.
