本项目将论证开发一种改进的CT检测器的可行性。具体来说，我们将致力于研究Lu2O3蚀刻的激光参数优化，以及在光产率和衰减时间测量方面的形貌和材料表征。同时，将努力修改和改进这种新材料的性能。几个Lu2O3样品将被激光蚀刻，选定的一个将光学耦合到商业线性光电二极管阵列。将对原型装置进行评估。虽然在第一阶段将只使用一维光电二极管阵列，但在第二阶段将使用16 x 16元器件。
英文摘要
This project will demonstrate the feasibility of the proposed development of a refined CT detector. Specifically, the effort will be undertaken on the research into laser parameter optimization for Lu2O3 etching along with morphology and material characterization in terms of light yield and decay time measurements. In parallel, an effort will be undertaken to modify and improve the properties of this new material. Several Lu2O3, samples will be laser etched and the selected one will be optically coupled to a commercial linear photodiode array. Evaluation of the prototype device will be performed. While only a one dimensional photodiode array will be used during the Phase I, a 16 x 16 element devices will be employed during Phase II.
