This grant supports the continued operation of the Northeast National Ion Microprobe Facility (NENIMF) as a National Secondary Ion Mass Spectrometry (SIMS) Facility serving the geoscience community. The principal strengths of SIMS relative to other micro-analytical techniques are its high spatial resolution and the capability for high-precision measurements of both concentration and isotopic composition of light elements such as hydrogen, lithium, boron, carbon, nitrogen, and oxygen. The analytical capabilities and expertise of the NENIMF are focused in two areas: determination of magmatic volatiles in silicate glasses and analysis of biogenic carbonates as records of climate change and its impacts on marine organisms, making the NENIMF a unique interdisciplinary resource to the geosciences community, with minimal overlap to the other National SIMS Facilities. Since January 2011, the NENIMF has accommodated 93 users from 47 different institutions, including 14 users from institutions outside the United States. Over the past 22 years, a total of 328 peer reviewed scientific papers have been published using data collected at the NENIMF for an average of 15 publications per year.The NENIMF is equipped with two Cameca SIMS instruments: an IMS 1280 and an IMS 3f. The IMS 1280 is a double focusing mass spectrometer with a large radius magnetic sector (585 mm), and ion optics optimized to attain a mass resolving power (MRP= M/delta M) of 6,000 without significant loss of secondary ion intensity. The IMS 3f is a double focusing mass spectrometer with a small radius magnetic sector that has been used for a wide spectrum of geochemical studies since 1978 and has been upgraded to Linux-based computer control of many components via Labview-based software (LabSIMS). The combination of these 2 instruments and the technical and scientific expertise of the NENIMF provides the geoscience community with a unique resource. Publications related to magmatic volatiles comprised 69% of the NENIMF total over the past 5 years, while 13% were focused on biogenic carbonates. In addition to these areas of specialization, NENIMF users have taken advantage of the Cameca IMS 1280 to work on a range of topics that include B isotopes in MORB glasses and subduction zone minerals, Zr in rutile geospeedometry, Ti diffusion in quartz, and U-Th-Pb dating of monazite and zircon. New analytical protocols developed at the NENIMF over the past few years include high-precision analysis of the isotopic composition of boron in low concentration basaltic glasses, and determination of D/H in the accessory mineral apatite. Support for the NENIMF meets the NSF Broader Impacts criteria in several different ways. Discovery and understanding are advanced while promoting teaching, training, and learning and participation of underrepresented groups is broadened through the involvement of undergraduates, graduate students, and postdocs. WHOI Undergraduate Summer Student Fellows, Postdoctoral Scholars, and WHOI/MIT Joint Program graduate students are specifically targeted for involvement in research projects with NENIMF personnel and WHOI faculty in which they are intimately involved with SIMS techniques. Involvement of young scientists in SIMS-based research is encouraged through annual short-courses. Infrastructure for research and education are enhanced through making both our existing analytical platforms, and those to be developed by the NENIMF personnel during the funding period, available to scientists and students from diverse disciplines. Research results are disseminated broadly to enhance scientific and technological understanding through an average of 15 publications per year that result from use of the facility.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该赠款支持东北国家离子微探针设施（Nenimf）作为为地球科学社区服务的国家二次离子质谱（SIMS）设施的持续运营。 SIMS相对于其他微型分析技术的主要优势是其高空间分辨率，以及对光浓度和同位素组成的高精度测量能力，例如氢，锂，锂，硼，碳，碳，氮和氧气。 Nenimf的分析能力和专业知识集中在两个领域：确定硅酸盐眼镜中的岩浆挥发物以及生物碳酸盐的分析，作为气候变化的记录及其对海洋生物的影响，使Nenimf成为对地球科学社区的独特跨学科资源，并具有最小的国家模拟物质，对其他国家模仿者的各种设施的功能。自2011年1月以来，Nenimf已容纳来自47个不同机构的93位用户，其中包括来自美国以外机构的14个用户。在过去的22年中，使用Nenimf的数据平均每年收集15个出版物，总共发表了328个同行评审的科学论文。Nenimf配备了两种Cameca Sims Instruments：AN IMS 1280和AN IMS 3F。 IMS 1280是具有较大半径磁性扇形（585 mm）的双聚焦质谱仪，并且已优化了离子光学元件，以达到6,000的质量分辨能力（MRP = m/delta m），而中等离子强度的显着损失。 IMS 3F是一个双重聚焦质谱仪，具有小半径磁性扇形，自1978年以来已用于广泛的地球化学研究，并通过基于Labview的软件（LabSIMS）升级为基于Linux的计算机控制。这两种工具的结合以及Nenimf的技术和科学专业知识为地球科学界提供了独特的资源。与岩浆挥发物有关的出版物占过去5年中NENIMF总数的69％，而13％的出版物则关注生物碳酸盐。除这些专业领域外，Nenimf用户还利用了Cameca IMS 1280的优势来处理一系列主题，其中包括MORB眼镜和俯冲带中的B同位素矿物质，金黄色地质测定法中的ZR，Ti在Quartz中的扩散以及Monazite和Monazite和Zircon的U-th-PB量。在过去的几年中，在Nenimf开发的新分析方案包括对低浓度玄武岩玻璃中硼的同位素组成的高精度分析，以及在辅助矿物磷灰石中测定D/H。对Nenimf的支持以几种不同的方式符合NSF的更广泛影响标准。通过本科生，研究生和博士后的参与来扩展，发现和理解是在促进代表性不足的群体的教学，培训和学习和参与的同时进行的。 WHOI本科夏季学生研究员，博士后学者和WHOI/MIT联合课程研究生专门针对与Nenimf人员和Whoi教职员工参与研究项目，与他们密切参与SIMS技术。通过年度缩短工作鼓励年轻科学家参与基于模拟的研究。通过建立我们现有的分析平台以及Nenimf人员在资金期间开发的研究和教育基础设施，可以提高研究和教育的基础设施，从而提供了来自不同学科的科学家和学生。研究结果被广泛传播，以通过使用该设施的平均每年15个出版物来增强科学和技术理解。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估来审查标准的评估值得支持的。
