This Major Research Instrumentation (MRI) award supports the acquisition of an integrated Laser Ablation Time Of Flight Inductively-Coupled Plasma Mass Spectrometer (LA-TOF-ICP-MS) system for research and teaching at the University of California Santa Barbara (UCSB). This instrumentation will facilitate the investigations of fourteen UCSB faculty and researchers, their students, and collaborators. It will also enable access for a broad range of researchers and students elsewhere in California and globally. The new analytical capabilities of this system will improve the quality of undergraduate learning and instruction in earth science and allied fields, provide new opportunities s for undergraduate and graduate research projects, and form the basis for the creation of novel and engaging analytical geochemistry coursework. The PIs on this award actively participate in the Geochemical Society’s capacity-building grants program, and the NSF-funded ‘Advancing Geochronology Science, Spaces, and Systems’ (AGeS3), which fund research opportunities for underrepresented students as well as scientists from developing countries.The LA-TOF-ICP-MS system enables rapid three-dimensional imaging of elemental and isotopic variations in geological and biological materials at the micron scale with minimal sample preparation. Key capabilities of this system include the ability to scan the entire mass spectrum from sodium to uranium in less than 30 microseconds, and the routine production of quantitative images at a rate of up to 1000 pixels per second at detection limits in the parts-per-million range. Specific research objectives include: 1) dating complexly zoned minerals to understand a range of magmatic, metamorphic, sedimentary, and tectonic processes, 2) characterizing the often-complex distribution of U in carbonates to obtain better U-Pb ages, and; 3) retrieving detailed paleoclimate proxy records from carbonates.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.

这项主要的研究仪器（MRI）奖支持收购综合的激光消融时间，用于在加利福尼亚大学圣塔芭芭拉大学（UCSB）的研究与教学系统中，用于研究与教学的综合激光消融时间。该仪器将促进14名UCSB教师和研究人员，他们的学生和合作者的调查。它还将为加利福尼亚州和全球其他地方的广泛研究人员和学生提供访问。该系统的新分析能力将提高地球科学和盟军领域的本科学习和教学的质量，为本科和研究生研究项目提供新的机会，并为创建新颖和引人入胜的分析地球化学课程构成基础。该奖项上的PI积极参与地球化学社会的能力建设赠款计划，以及NSF资助的“推进地球学科学，空间和系统”（AGES3），为代表性不足的学生以及发展中国家的科学家提供研究机会。微米量表具有最小的样品制备。该系统的关键能力包括在不到30微秒的情况下从钠到铀扫描整个质谱的能力，以及以每秒高达1000像素的速度在零件范围内的检测限制的定量图像的常规产生。特定的研究目标包括：1）复杂的分区矿物质，以了解一系列岩浆，变质，沉积和构造过程，2）表征U在碳酸盐中经常复杂的分布以获得更好的U-PB年龄，并且； 3）从碳酸盐中检索详细的古气候代理记录。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，被视为通过评估来获得珍贵的支持。
