0744154AgueThis grant will support the purchase of a new electron probe microanalyzer (EPMA) at Yale University. The current JEOL JXA-8600 EPMA has played a vital role in research and undergraduate and graduate level teaching over the last ~17 years, but the natural aging of mechanical and computer components, the obsolescence of much of the computer software and hardware, and the expanding needs of current and future research programs require replacement of the existing instrument. New research will be critically dependent on imaging and chemically mapping features one to two orders of magnitude smaller than we can currently resolve, on two-dimensional chemical mapping using wavelength-dispersive and energy-dispersive spectrometers, and on newly available wavelength-dispersive spectrometer (WDS) designs that will improve count rates and peak-to-background ratios. The research base that will support a new instrument comprises a broad spectrum of field, laboratory, experimental, and theoretical projects. The new EPMA will, together with a newly-purchased SEM, form the basis of a coherent "Microbeam Center" in the Department of Geology and Geophysics. This center will provide the analytical capabilities necessary for the next generation of research and teaching at Yale as well as for the broader educational, scientific, and industrial communities of southern New England.

0744154Ague这笔赠款将支持在耶鲁大学购买新型电子探针微量分析仪（EPMA）。目前的 JEOL JXA-8600 EPMA 在过去约 17 年里在研究以及本科生和研究生水平的教学中发挥了至关重要的作用，但机械和计算机组件的自然老化、大部分计算机软件和硬件的过时以及当前和未来研究计划不断扩大的需求需要更换现有仪器。新的研究将主要依赖于比我们目前所能解析的小一到两个数量级的成像和化学映射特征，使用波长色散和能量色散光谱仪进行二维化学映射，以及新推出的波长色散光谱仪。 WDS）设计将提高计数率和峰背景比。支持新仪器的研究基地包括广泛的现场、实验室、实验和理论项目。新的 EPMA 将与新购买的 SEM 一起构成地质与地球物理系连贯的“微束中心”的基础。 该中心将为耶鲁大学下一代研究和教学以及新英格兰南部更广泛的教育、科学和工业社区提供必要的分析能力。
