Acquisition of a New Electron Microprobe

9508616 Leger美国自然历史博物馆矿物科学系（AMNH）和哥伦比亚大学地质科学系（LDEO）将建立一个联合电子显微探针实验室。这一发展建立在这些部门之间的许多预先存在的联系之上，例如研究生研究的联合计划，研究合作，以及实验岩石学，x射线和FTIR实验室的共享使用。AMNH将获得一种新的电子微探针，以取代已有18年历史的ARL SEMQ，并为LDEO研究人员提供光元素分析和图像分析处理的附加功能，这些功能目前是他们已有10年历史的Cameca MBX无法实现的。这笔拨款将支持新Cameca电子显微探针80万美元资本成本的一半，另一半将由AMNH和哥伦比亚大学平分。此外，AMNH还支持一个全职博士级别的研究职位（PI）来管理该设施。用一个最先进的仪器取代两个老化的微探针，在操作效率、分析设备的充分利用、内部操作的成本效率和最大限度地利用稀缺的仪器费用方面具有优势。新仪器将提高两个机构和纽约大都会地区的多名研究人员的工作效率和分析能力，包括纽约城市大学（CUNY）系统的学生。一个单独的实验室还有一个额外的优势，它将使AMNH和LDEO的科学家更紧密地联系在一起，并鼓励新的智力联系。* * *

9508616 Leger The Department of Mineral Sciences at the American Museum of Natural History (AMNH) and Department of Geological Sciences (LDEO) of Columbia University will establish a joint electron microprobe laboratory. This development builds upon numerous pre- existing links between these departments such as a joint program of Graduate Studies, research collaboration, and shared use of experimental petrology, x-ray, and FTIR laboratories. AMNH will acquire of a new electron microprobe to replace the 18-year old ARL SEMQ in current operation and to provide LDEO researchers with added capabilities in the analysis of light elements and in image analysis processing not currently possible with their 10- year old Cameca MBX. This grant supports half of the $800,000 capital cost of a new Cameca electron microprobe and half will be supported equally by AMNH and Columbia University. In addition, AMNH supports a full-time Ph.D.-level research position (the PI) to manage the facility. Replacing the two aging microprobes with a single state-of-the-art instrument has advantages for efficiency of operation, full utilization of the analytical facility, cost efficiency of internal operation, and maximizing the use of scarce instrumentation dollars. The new instrument will lead to increased productivity and analytical capability for multiple investigators at both institutions and in the New York metropolitan area including students from the City University of New York (CUNY) system. A single laboratory has the additional advantage that it will bring scientists from AMNH and LDEO closer together and encourage new intellectual links. ***
