High-Pressure Diffraction Studies Using A Linear Position Sensitive Detector

在这个项目中，一种新型的探测器，将被用于分析钻石铁砧的衍射x射线，高压实验。新方法将提高大约一个数量级的分辨率，这将使确定低对称相位的晶格几何形状成为可能。此外，新的探测器将与正在计划的新一代同步加速器更加兼容。新的探测器将被用来首次精确地获得各种低对称、高压相的单质固体、硅酸盐和氧化物在地球下地幔和地核的压力下的状态方程。然后，这些数据可以应用于地震和地球内部的其他研究。

This is a project in which a new type of detector, will be used to analyze diffracted X-rays from diamond anvil, high-pressure experiments. The new method will increase the resolution by approximately an order of magnitude, which will make it possible to determine the lattice geometry for low-symmetry phases. In addition, the new detector will be more compatible with new generations of synchrotrons now being planned. The new detector will be used to obtain the first accurate structural information and equations of state of a variety of low-symmetry, high- pressure phases of elemental solids, silicates, and oxides under pressures characteristic of the lower mantle and core of the earth. The data can then be applied to seismic and other studies of the earth's interior.
