This award from the Major Research Instrumentation Program (MRI) provides funds for the acquisition and technical support of a Multi-Collector Thermal Ionization Mass Spectrometer (MC-TIMS) for isotopic research in the Earth and Planetary Sciences Department (EAPS) at Northwestern University (NU). The acquisition of the MC-TIMS coincides with the establishment of a new analytical facility in the EAPS Department that will support functionalities in isotope (radiogenic and stable), aqueous, organic, and sedimentary geochemistry. Within this complex, the MC-TIMS will be the primary research tool in the Radiogenic Isotope Laboratory, which will encompass a clean laboratory for sample preparation and a climate-controlled instrument room. The MC-TIMS will benefit a cross-disciplinary community of faculty and students at NU and other Chicago-area institutions, including the University of Chicago and the University of Illinois-Chicago. A comprehensive management plan will ensure the efficient and cost-effective operation of the instrument by internal and external users. Emphasis will be placed on the measurement of Ca, Nd, Re, Os, Sr, Th, and U isotope abundance variations to support single investigator and collaborative research activities in the areas of aqueous geochemistry, ground and surface water hydrology, chemical oceanography, paleoceanography, geomicrobiology, cosmochemistry, chemostratigraphy, and climate change, both modern and ancient. Graduate and undergraduate students will use the MC-TIMS to accomplish NSF-funded research, and the PI will directly integrate the instrument into courses featuring the theory and practice of radiogenic isotope geochemistry. Research and teaching activities employing the MC-TIMS will also include minority students from Evanston Township High School who are participating in project EXCITE at NU. The goal of EXCITE is to increase the number of underrepresented minorities majoring in science, engineering, mathematics, and technology at the college level. Lastly, the PI plans to create a radiogenic isotope intern program drawing from a consortium of 17 Chicago-area 2- and 4-year colleges whose student body is comprised of traditionally underrepresented groups. Interns will gain hands on experience with the MC-TIMS. Opportunities exist for interns to matriculate into the EAPS graduate program with the aid of special fellowships and scholarships offered by The Graduate School at NU.

该奖项来自重大研究仪器计划 (MRI)，为西北大学地球与行星科学系 (EAPS) 的同位素研究购买多收集器热电离质谱仪 (MC-TIMS) 提供资金（努）。收购 MC-TIMS 的同时，EAPS 部门建立了一个新的分析设施，该设施将支持同位素（放射性和稳定）、水性、有机和沉积地球化学方面的功能。在这个综合体中，MC-TIMS 将成为放射性同位素实验室的主要研究工具，该实验室将包括一个用于样品制备的洁净实验室和一个气候控制仪器室。 MC-TIMS 将使 NU 和其他芝加哥地区机构（包括芝加哥大学和伊利诺伊大学芝加哥分校）的教师和学生跨学科社区受益。全面的管理计划将确保内部和外部用户高效且经济高效地操作仪器。重点将放在 Ca、Nd、Re、Os、Sr、Th 和 U 同位素丰度变化的测量上，以支持水文地球化学、地下水和地表水水文学、化学海洋学、古海洋学领域的单一研究者和协作研究活动、地球微生物学、宇宙化学、化学地层学和气候变化，无论是现代的还是古代的。研究生和本科生将使用 MC-TIMS 完成 NSF 资助的研究，PI 将直接将该仪器整合到放射性同位素地球化学理论和实践课程中。采用 MC-TIMS 的研究和教学活动还将包括埃文斯顿镇高中的少数民族学生，他们正在参加 NU 的 EXCITE 项目。 EXCITE 的目标是增加大学级别的科学、工程、数学和技术专业中代表性不足的少数群体的数量。最后，PI 计划创建一个放射性同位素实习生项目，该项目由芝加哥地区 17 所 2 年制和 4 年制大学组成的联盟招募，这些大学的学生群体由传统上代表性不足的群体组成。实习生将获得 MC-TIMS 的实践经验。实习生有机会在 NU 研究生院提供的特殊奖学金和奖学金的帮助下入读 EAPS 研究生课程。
