Upgrade of X-Ray Diffractometer and Electron Microprobe Laboratories

小行星9810089 这笔赠款为耶鲁大学地质和地球物理系X射线衍射仪和电子微探针实验室的操作所需的仪器和计算机升级提供部分支助。 具体升级包括：（1）用现代化的基于PC的系统取代陈旧的XRD计算机和软件. (2)升级EMP上的能量色散检测器，以提高峰值分辨率，并能够检测轻元素（B、C、N、O、F）。(3)用现代化的个人电脑系统取代EMP上用于图像采集/处理、X射线绘图和能量色散谱采集和处理的过时计算机和软件。(4)更换EMP实验室中陈旧的碳涂层器。 XRD和EMP是教师，学生，博士后，研究机构和访问学者参与广泛研究的宝贵部门主力，包括：（1）野外变质和火成岩学，（2）实验岩石学/地球化学，（3）沉积和风化过程的地球化学，（4）经济地质学，（5）构造地质学和构造学，（6）古生物学，（7）考古测量学，（8）生物矿化。 ***

9810089 Ague This grant provides partial support for upgrading instrumentation and computers required for operation of the X-ray diffractometer (XRD) and electron microprobe (EMP) laboratories in the Department of Geology and Geophysics, Yale University. Specific upgrades include: (1) Replace obsolete XRD computer and software with modern PC- based system. (2) Upgrade the energy-dispersive detector on the EMP in order to improve peak resolution and enable detection of light elements (B, C, N, O, F). (3) Replace obsolete computer and software on EMP used for image acquisition/processing, X-ray mapping, and energy- dispersive spectrum acquisition and processing with modern PC-based system. (4) Replace obsolete carbon coater in EMP laboratory. The XRD and EMP are invaluable Departmental workhorses for faculty, students, post-docs, research affiliates, and visiting scholars involved in a broad spectrum of research, including: (1) Field-based metamorphic and igneous petrology, (2) Experimental petrology/geochemistry, (3) Geochemistry of sedimentary and weathering processes, (4) Economic geology, (5) Structural geology and tectonics, (6) paleontology, (7) Archaeometallurgy, and (8) Biomineralization. ***
