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.

这笔赠款支持东北国家离子微探针设施（NENIMF）作为服务于地球科学界的国家二次离子质谱（西姆斯）设施的继续运作。西姆斯相对于其他微量分析技术的主要优势是其高空间分辨率和高精度测量轻元素（如氢、锂、硼、碳、氮和氧）的浓度和同位素组成的能力。NENIMF的分析能力和专业知识集中在两个领域：硅酸盐玻璃中岩浆挥发物的测定和生物碳酸盐的分析，作为气候变化及其对海洋生物影响的记录，使NENIMF成为地球科学界独特的跨学科资源，与其他国家西姆斯设施的重叠最小。自2011年1月以来，NENIMF已容纳了来自47个不同机构的93名用户，其中包括来自美国以外机构的14名用户。在过去的22年里，共有328篇同行评审的科学论文使用NENIMF收集的数据发表，平均每年发表15篇论文。NENIMF配备了两台Cameca西姆斯仪器：IMS 1280和IMS 3f。IMS 1280是一款双聚焦质谱仪，具有大半径磁扇区（585 mm）和优化的离子光学器件，可实现6，000的质量分辨能力（MRP= M/Δ M），而不会显著损失二次离子强度。IMS 3f是一种双聚焦质谱仪，具有小半径磁扇区，自1978年以来一直用于广泛的地球化学研究，并已通过基于Labview的软件（LabSIMS）升级为基于Linux的计算机控制许多组件。这两种仪器与NENIMF的技术和科学专业知识相结合，为地球科学界提供了独特的资源。过去5年，与岩浆挥发物相关的出版物占NENIMF总数的69%，而13%则集中在生物碳酸盐上。除了这些专业领域外，NENIMF用户还利用Cameca IMS 1280研究了一系列课题，包括MOR B玻璃和俯冲带矿物中的B同位素、金红石地质速度测量中的Zr、石英中的Ti扩散以及独居石和锆石的U-Th-Pb定年。NENIMF在过去几年中开发的新分析协议包括低浓度玄武岩玻璃中硼同位素组成的高精度分析，以及辅助矿物磷灰石中D/H的测定。对NENIMF的支持以几种不同的方式满足NSF更广泛影响标准。发现和理解是先进的，同时促进教学，培训和学习，并通过本科生，研究生和博士后的参与扩大了代表性不足的群体的参与。WHOI本科暑期学生研究员，博士后学者和WHOI/麻省理工学院联合项目研究生是专门针对参与研究项目与NENIMF人员和WHOI教师，他们密切参与西姆斯技术。通过年度短期课程鼓励青年科学家参与基于SIMS的研究。通过使我们现有的分析平台以及NENIMF人员在资助期间开发的平台，为来自不同学科的科学家和学生提供研究和教育基础设施。通过使用该设施，研究成果被广泛传播，以提高科学和技术的理解。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
