This award supports the upgrade of the Thermal Ionization Mass Spectrometer (TIMS) currently installed at the University of California, Santa Cruz (UCSC). The instrumentation upgrade will be installed in a multi-user facility which is focused on data collection and training for undergraduate, graduate, and postdoctoral researchers and is incorporated into the classroom activities of some of the nation’s most diverse Earth Science classrooms. This TIMS instrument is used to measure the natural isotopic variations in earth and ocean samples. This analytical tool is incorporated into UCSC classroom instruction but also serves as the primary tool in geologic and climate research projects funded by the National Science Foundation. For example, a major use has been to produce absolute formation ages for rocks and minerals as apart of Earth and Ocean science investigations. This project supports the upgrade the instrumental ion detection system (how isotopic variations are detected) and the computer system that controls the instrument. These upgrades will both improve the quality of data and extend the lifetime of this instrument by replacing the original computer hardware and software. The upgrade of the IsotopX Phoenix Thermal Ionization Mass Spectrometer (TIMS) currently installed at UCSC is supported by this award. This instrument was originally installed in a multi-user facility as a part of a 2015 NSF MRI award (1532276) and has since served to produce U, Th, Pb and Sr isotopic data while training UCSC students, postdocs, and faculty researchers. The primary use of the instrument has been to produce U-Pb and U-Th radioisotopic ages for studies that range in time and applications from early solar system studies to Pleistocene climate. In addition to these geochronologic efforts, the instrument is used to produce Sr and Pb isotopic data for UCSC researchers from the Departments of Ocean Sciences, Anthropology and Earth and Planetary Sciences. The project will support the upgrade of the UCSC TIMS with the IsotopX ATONA amplifier technology and the accompanying 10kV high voltage (HV) and computer hardware/software systems. Collectively these modifications will: 1) permit ATONA-Daly collection of large U-series isotopic ratios, improving the precision of geochronologic dates 2) improve transmission of low abundance isotopes from the new HV system; 3) remove the need to exchange amplifier cards between different experiments and 4) ensure a stable computer configuration for this facility for years to come.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.

该奖项支持目前在加利福尼亚大学圣克鲁斯分校（UCSC）安装的热电离质谱仪（TIMS）的升级。该仪器升级将安装在多用户设施中，该设施专注于本科，研究生和博士后研究人员的数据收集和培训，并将其纳入美国一些最受欢迎的地球科学教室的课堂活动中。该TIMS仪器用于测量地球和海洋样品中的天然同位素变化。该分析工具已纳入UCSC课堂教学中，但也是国家科学基金会资助的地质和气候研究项目的主要工具。例如，主要用途是为地球和海洋科学调查产生绝对的岩石和矿物质年龄。该项目支持升级仪器离子检测系统（同位素变化）这些升级将通过更换原始的计算机硬件和软件来提高数据质量并延长该乐器的寿命。该奖项支持了当前在UCSC上安装的Isotopx Phoenix热电离质谱仪（TIMS）的升级。该乐器最初是在多用户设施中安装的，作为2015 NSF MRI奖（1532276）的一部分，此后一直在培训UCSC学生，博士后和教职员工研究人员时生产U，TH，PB和SR同位素数据。该仪器的主要用途是生产U-PB和U-TH放射性化年龄，用于时间和应用，从早期太阳系研究到更新世的气候。除了这些年代学工作外，该仪器还用于为来自海洋科学，人类学，地球和行星科学系的UCSC研究人员生成SR和PB同位素数据。该项目将使用Isotopx Atona放大器技术以及参与的10kV高压（HV）和计算机硬件/软件系统来支持UCSC TIMS的升级。这些修改总共将：1）允许大型U系列同位素比的Atona-Daly收集，提高了测量日期的精度2）改善新的HV系统中低抽象同位素的传播； 3）删除在不同实验之间交换放大器卡的需求和4）确保在未来几年内确保该设施的计算机配置稳定。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子的优点和更广泛的影响来评估NSF的法定任务，并被认为是宝贵的支持。
