An Investigation Of Energy Migration In Rare Earth Oxyorthosilicate Scintillation Materials, Harold Edward Rothfuss

Doctoral Dissertations

In most scintillator applications, the energy resolution is an important scintillation property and is related to other scintillator properties. In order to observe how these properties relate to the energy resolution, a simulation was created to quantify most of these characteristics for a LSO:Ce scintillator. These results were validated with good agreement to experimental results. From the separable components of the simulation, an understanding of the contributions to the energy resolution broadening was developed. A thought to improve the energy resolution by improving the energy migration was tested by observing and modifying the scintillation kinetics of YSO:Ce. The scintillation kinetics …
