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（SIMS）设施的持续运行。相对于其他微量分析技术，SIMS 的主要优势在于其高空间分辨率以及能够高精度测量氢、锂、硼、碳、氮和氧等轻元素的浓度和同位素组成。 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 SIMS 设施的重叠最小。自2011年1月以来，NENIMF已接待了来自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 22 年中，利用 NENIMF 收集的数据总共发表了 328 篇同行评审的科学论文，平均每年发表 15 篇论文。NENIMF 配备了两台 Cameca SIMS 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) 和经过优化的离子光学器件，可实现 6,000 的质量分辨率 (MRP= M/delta M)，而不会显着损失二次离子强度。 IMS 3f 是一款具有小半径磁扇区的双聚焦质谱仪，自 1978 年以来一直用于广泛的地球化学研究，并已升级为通过基于 Labview 的软件 (LabSIMS) 对许多组件进行基于 Linux 的计算机控制。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% 则重点关注生物碳酸盐。除了这些专业领域之外，NENIMF 用户还利用 Cameca IMS 1280 来研究一系列主题，包括 MORB 玻璃和俯冲带矿物中的 B 同位素、金红石地球速度测量中的 Zr、石英中的 Ti 扩散以及 U-独居石和锆石的 Th-Pb 定年。 NENIMF 过去几年开发的新分析方案包括低浓度玄武岩玻璃中硼同位素组成的高精度分析，以及副矿物磷灰石中 D/H 的测定。对 NENIMF 的支持以多种不同方式满足 NSF 更广泛影响标准。通过本科生、研究生和博士后的参与，在促进教学、培训和学习的同时，促进发现和理解，并扩大代表性不足群体的参与。 WHOI 本科生暑期学生研究员、博士后学者和 WHOI/MIT 联合项目研究生专门参与与 NENIMF 人员和 WHOI 教员一起的研究项目，在这些项目中他们密切参与 SIMS 技术。通过年度短期课程鼓励年轻科学家参与基于 SIMS 的研究。通过向不同学科的科学家和学生提供我们现有的分析平台以及 NENIMF 人员在资助期间开发的分析平台，研究和教育基础设施得到加强。研究成果通过使用该设施每年平均发表 15 篇出版物来广泛传播，以增强科学和技术理解。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响进行评估，被认为值得支持审查标准。
