Acquisition of a New Electron Microprobe

9508616美国自然历史博物馆矿物科学部和哥伦比亚大学地质科学系将建立一个联合电子微探针实验室。这一发展建立在这些部门之间的许多预先存在的联系上，例如研究生研究的联合计划、研究合作以及共享使用实验岩石学、X射线和FTIR实验室。AMNH将获得一种新的电子探针，以取代目前运行中已有18年历史的ARL SEMQ，并为LDEO研究人员提供目前已有10年历史的Cameca MBX无法增加的光元素分析和图像分析处理能力。这笔赠款支持一个新的Cameca电子微探测器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支持。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。用一台最先进的仪器取代两个老化的微探头，在操作效率、分析设备的充分利用、内部操作的成本效益和最大限度地利用稀缺的仪器资金方面具有优势。新仪器将提高这两个机构和纽约大都市区多名调查员的工作效率和分析能力，包括纽约市立大学系统的学生。一个单一的实验室还有一个额外的优势，那就是它将使AMNH和LDEO的科学家更紧密地联系在一起，并鼓励新的学术联系。***

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. ***
