EAR-0307257FodorThis project applies NSF funds to upgrading the ARL-SEMQ six spectrometer electron microprobe in the Department of Marine, Earth and Atmospheric Sciences at North Carolina State University. The microprobe upgrade will modernize and broaden the capabilities of students and faculty for research and teaching endeavors that use digital imaging and quantitative analyses in mineralogy, in the petrology of igneous, metamorphic and sedimentary rocks, terrestrial sediment and invertebrate paleontology. These include investigations of basaltic lavas and xenoliths within, mantle xenoliths, North Carolina granitoid rocks and low-to-high grade contact and regional metamorphic rocks, terrestrial sediment and marine phosphate studies and trace-element "mapping" in dinosaur bones. The Upgrade will bring the microprobe up to state-of-the-art analytical capability by adding (i) the capacity to do backscattered electron and x-ray imaging of geologic material with advanced software for imaging functions, by (ii) applying a Windows-based software for the microprobe operation, and (iii) by implementing a Pentium-processor computer to accommodate all imaging and operational softwares. The upgraded NCSU microprobe lab will enable students and faculty to continue publishing research in major journals and to teach and train modern analytical instrument techniques to undergraduate and graduate students. Broader impacts of this project include that students and faculty from neighboring universities will have access to the upgraded instrument, some of which are minority-based schools (NC Central University; Robeson Community College) and women's colleges (Meredith; Peace). NCSU supports this instrument upgrading by matching NSF funding with $18,500, or about 30% of the total costs for all purchases, installation and user training.

EAR-0307257 Fodor该项目利用美国国家科学基金会的资金，对北卡罗来纳州立大学海洋、地球和大气科学系的ARL-SEMQ六光谱电子探头进行升级。微探头的升级将使学生和教师的研究和教学工作能力现代化，并扩大他们的能力，这些学生和教师在矿物学、火成岩、变质岩和沉积岩、陆地沉积物和无脊椎动物古生物学的岩石学中使用数字成像和定量分析。其中包括调查玄武岩熔岩和包体、地幔包体、北卡罗来纳州花岗岩类岩石和低-高级接触岩和区域变质岩、陆地沉积物和海洋磷酸盐研究以及恐龙骨骼中的微量元素“绘图”。这次升级将使微探头具备最先进的分析能力，增加(1)利用先进的成像功能软件对地质材料进行背散射电子和X射线成像的能力，(2)应用基于Windows的软件进行微探头操作，以及(3)安装一台奔腾处理器计算机，以容纳所有成像和操作软件。升级后的NCSU微探针实验室将使学生和教职员工能够继续在主要期刊上发表研究成果，并向本科生和研究生教授和培训现代分析仪器技术。该项目的更广泛影响包括，邻近大学的学生和教职员工将可以使用升级后的仪器，其中一些是以少数群体为基础的学校(北卡罗来纳州中央大学；罗伯逊社区学院)和女子学院(梅雷迪思；和平)。NCSU通过将NSF资金与18,500美元(约占所有购买、安装和用户培训总成本的30%)相匹配来支持此仪器升级。
