Funds are provided to acquire a modern electron probe micro-analyzer (EPMA) to support several Old Dominion University (ODU) research programs, as well as activities at Norfolk State University (NSU) and Hampton University (HU), both minority-serving institutions, and the College of William and Mary (W&M). These research programs include the pioneering iron grain tracer technique, which employed the existing EPMA to measure grain chemistry over the last 16 years for research on Arctic sea ice and climate change, research on fish population dynamics using detailed (10 ìm) otolith-layer chemistry that is essential for future management of fish stocks, metal restoration for priceless marine artifacts such as the USS Monitor, investigations of delamination in Aluminum-Lithium alloys important to space exploration, studies of electrodes used in large particle accelerators (e.g., Jefferson Lab and Fermilab and the prospective International Linear Collider, a nine billion dollar project), and calibrations of new laser analysis techniques with wide applications for research and industry. The growing list of innovative research projects at ODU and other local institutions requiring an EPMA and other types of microanalyses has prompted a commitment by ODU to expand the building space and support for such equipment. ODU is committed to ensuring that a qualified, experienced EPMA operator is available full-time to facilitate this research and that the new EPMA is maintained properly. The requested EPMA will replace a 39 year old ETEC EPMA that is now well beyond retirement age. Recent developments in EPMA instrumentation has made extended overnight and weekend automated operation possible and safe with offsite monitoring. This allows for expanded usage of an EPMA because much of the currently funded iron grain work can largely be done after normal work hours, opening the instrument to greater daytime usage requiring hands-on operation.The requested EPMA is part of a major research infrastructure plan at ODU. The new Research Facility that will house the EPMA and other microanalysis instrumentation is under construction and scheduled for completion in early 2009 and will be a regional microanalyses facility. The EPMA will provide ?hands-on? research experience for graduate and undergraduate students at ODU, NSU, HU, W&M, and other institutions. An estimated 12 faculty researchers, 21 graduate and 58 undergraduate students from these institutions will use the new EPMA in the first few years. Besides research, the EPMA will be used for classroom demonstrations and exercises for both graduate and undergraduate courses. The management plan provides for usage charges to cover a maintenance contract, supplies, and an experienced operator well beyond the three years of the grant. The long-term operation and maintenance is guaranteed by the College of Sciences as part of the College?s research infrastructure improvement plan.

提供资金购买现代电子探针显微分析仪（EPMA），以支持几个老自治领大学（ODU）的研究计划，以及在诺福克州立大学（NSU）和汉普顿大学（HU）的活动，这两个少数民族服务机构，以及威廉和玛丽学院（W M）。这些研究项目包括开创性的铁颗粒示踪技术，该技术在过去16年中利用现有的EPMA测量颗粒化学，用于研究北极海冰和气候变化，使用详细的（10 μ m）耳石层化学研究鱼类种群动态，这对未来的鱼类种群管理至关重要，金属修复无价的海洋文物，如USS Monitor，对空间探索重要的铝-锂合金中的分层的研究，对用于大粒子加速器的电极的研究（例如，杰斐逊实验室和费米实验室和未来的国际直线对撞机，一个90亿美元的项目），并校准新的激光分析技术与广泛的应用，为研究和工业。ODU和其他地方机构越来越多的创新研究项目需要电子探针分析和其他类型的微量分析，这促使ODU承诺扩大建筑空间和对此类设备的支持。ODU致力于确保有一个合格的，经验丰富的EPMA操作员全职促进这项研究，并妥善维护新的EPMA。所要求的EPMA将取代一个39岁的ETEC EPMA，现在远远超过退休年龄。EPMA仪器的最新发展使得延长夜间和周末的自动化操作成为可能，并且通过场外监测变得安全。这使得EPMA的使用范围扩大，因为目前资助的大部分铁粒工作可以在正常工作时间之后完成，从而使仪器能够在白天使用，需要动手操作。所要求的EPMA是ODU主要研究基础设施计划的一部分。新的研究设施将容纳电子探针分析仪和其他微量分析仪器，该设施正在建设中，定于2009年初完工，将成为一个区域微量分析设施。EPMA将提供？亲自动手在ODU，NSU，HU，WM和其他机构的研究生和本科生的研究经验。据估计，这些机构的12名研究人员、21名研究生和58名本科生将在头几年使用新的电子探针。除了研究之外，EPMA还将用于研究生和本科生课程的课堂演示和练习。管理计划提供使用费，以支付远远超过赠款三年的维修合同、用品和一名有经验的操作员。长期的运行和维护是由科学学院作为学院的一部分来保证的吗？的研究基础设施改善计划。
