Facility Support: The UCLA National ION Microprobe

这笔拨款将继续支持加州大学洛杉矶分校离子微探针实验室作为地球和行星科学研究的国家设施。它使合格的外部调查人员能够进入该设施。此外，它允许：(1)进一步发展分析方法，利用SIMS的独特优势，对与地球化学和地质年代学问题有关的同位素丰度进行现场分析；(2)加州大学洛杉矶分校CAMECA ims 1270关键部件的硬件升级，将显著延长其作为最先进仪器的使用寿命；(3)发展以K-12学生和教师为重点的教育和推广计划，并为加州大学洛杉矶分校的本科生建立暑期实习计划。与NASA天体生物学研究所和加州科学项目建立了伙伴关系，以利用教育和推广机会。加州大学洛杉矶分校国家离子微探针设备产生的数据导致了一系列重大发现，从构造学和火成岩过程到沉积过程，古气候学和古生物学，地球最早的历史和太阳系的起源和早期演化，自1995年以来已在120篇科学文章中详细介绍。目前，近36个nsf支持的项目依赖于该设施在这些不同领域进行研究。根据目前的兴趣水平，我们预计高分辨率离子微探针的独特功能在未来几年将保持高需求

McKeegan0421795This grant provides continued support of the UCLA ion microprobe laboratory as a national facility for research in the earth and planetary sciences. It enables access to the facility by qualified external investigators. In addition, it permits: (1) Further development of analytical methods that take advantage of the unique strengths of SIMS for in situ analyses of isotopic abundances relevant to problems in geochemistry and geochronology; (2) Hardware upgrades to critical components of the UCLA CAMECA ims 1270 that will significantly extend its life as a state-of-the-art instrument; and (3) Development of an education and outreach program focused upon K-12 students and teachers and establishment of a summer intern program for UCLA undergraduates. Partnerships are established with the NASA Astrobiology Institute and with the California Science Project in order to leverage education and outreach opportunities. Data produced from the UCLA national ion microprobe facility have led to an array of significant discoveries in fields ranging from tectonics and igneous processes to sedimentary processes, paleoclimatology and paleobiology, the earliest history of the Earth and the origin and early evolution of the Solar System that have been detailed in 120 scientific articles since 1995. Presently, nearly three dozen NSF-supported projects are reliant upon the facility to conduct research in these diverse fields. Based upon current interest levels, we expect that the unique capabilities of the high-resolution ion microprobe will remain in high demand in the coming years.***
