Upgrade of JEOL JXA 8600 electron microprobe at the University of Georgia

Swanson 0947187该奖项在12个月内为NSF提供了181，586美元的资金，用于购买三个主要的电子微探针组件;能量色散分析光谱仪（EDS）、Tracor北方光谱仪自动化系统和PAC X射线计数电子设备，这些都需要更换机构？s EMP。升级后的仪器将用于岩石学研究和分析考古材料。将评估蓝岭（阿巴拉契亚造山带南部）的超镁铁质岩石的起源。PI还将使用该仪器研究来自里道特火山的细粒安山岩、来自北卡罗来纳州西部的花岗岩、来自南美洲的地壳熔体、含水和挥发相、行星物质和地球中的交代流体？的斗篷。此外，升级EMP将用于了解矿物成分，分区和相比例。机构和外部合作者也将得到分析支持。所要求的设备是保持设施正常运行所必需的。从历史上看，EMP实验室已经产生了大约100篇研究论文，许多摘要和30多个硕士学位。博士论文学位论文EMP设施支持UGA和东南部其他地球科学部门的地质和化学部门。提案中概述的一项新举措是利用该设施支持东南部4年制院校的学生更广泛地参与，这些学生在校园内无法使用微探针设施。地质部为该仪器提供服务合同，并支助一名全职电子探针实验室协调员。技术人员每天使用仪器，并为用户提供时间安排和培训。*

Swanson0947187This award provides $181,586 in NSF funding over 12 months to acquire three major electron microprobe components; the energy dispersive analytical spectrometer (EDS), the Tracor Northern spectrometer automation system and the PAC X-ray counting electronics which all need replacing on the institution?s EMP. This upgraded instrument will be used for petrologic studies and analyzing archaeological materials. Ultramafic rocks from the Blue Ridge (southern Appalachian Orogen) will be assessed for origin. The PIs will also use the instrument to study fin-grained anhydrites from the Redoubt Volcano, granitic rocks from western North Carolina, crustal melts from South America, hydrous and volatile phases, planetary materials, and metasomatic fluids in the Earth?s mantle. Additionally, the upgrade EMP will be used for understanding mineral composition, zoning and phase proportions. Institutional and outside collaborators will also be analytically-supported. This requested equipment is needed to keep the facility up and running. Historically, the EMP lab has led to approximately 100 research papers, numerous abstracts and more than 30 M.S. theses and Ph.D. dissertations. The EMP facility supports Geology and Chemistry departments at UGA and other geoscience departments in the Southeast. A new initiative outlined in the proposal is to use the facility to support wider participation by students at 4-year institutions in the Southeast who do not have on-campus access to a microprobe facility. The Department of Geology provides a service contract for this instrument and supports a full-time Electron Microprobe Laboratory Coordinator. The technician works with the instrument day-to-day and provides scheduling and training for users.***
