This grant supports the UCLA ion microprobe as a national facility for research in the earth and planetary sciences by enabling access to qualified external investigators and supporting continued development of analytical methods that take advantage of the unique strengths of secondary ion mass spectrometry (SIMS) for in situ isotopic analyses. Our vision is that costly geochemical tools, such as the CAMECA ims 1270 ion microprobe, should be a community resource supported in centers with the scientific and technical expertise needed to fully exploit their potential. Prior NSF support has led to numerous significant discoveries in fields ranging from tectonics and igneous processes to sedimentology, paleoclimatology and paleobiology, the earliest history of the Earth and the origin and early evolution of the Solar System. In the current grant period, our goal is to ensure that the nation's geochemists, cosmochemists, and geochronologists continue to have access to our world-leading facilities at a level commensurate with our historic productivity, provide UCLA scientists the resources to continue to develop and refine existing and new SIMS methods for research in geochemistry, cosmochemistry, and geochronology, and undertake instrument modifications that lead to improvements in data acquisition and expanded capabilities that facilitate new types of investigations. Research training will continue to be a high priority and UCLA scientists will engage in synergistic activities both locally and nationally, including professional programs and K-12 education and outreach.

这笔拨款支持加州大学洛杉矶分校离子微探针作为地球和行星科学研究的国家设施，使其能够获得合格的外部研究人员，并支持利用二次离子质谱法（SIMS）的独特优势进行原位同位素分析的分析方法的持续发展。我们的愿景是，昂贵的地球化学工具，如CAMECA ims 1270离子微探针，应该成为一种社区资源，在具有充分发挥其潜力所需的科学和技术专业知识的中心得到支持。美国国家科学基金会先前的支持导致了许多领域的重大发现，从构造学和火成岩过程到沉积学，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。在目前的拨款期内，我们的目标是确保美国的地球化学家、宇宙化学家和地质年代学家继续能够以与我们历史生产力相称的水平使用我们世界领先的设施，为加州大学洛杉矶分校的科学家提供资源，继续开发和完善现有的和新的SIMS方法，用于地球化学、宇宙化学和地质年代学的研究。并对仪器进行改进，从而改善数据采集和扩大能力，促进新型调查。研究培训将继续是重中之重，加州大学洛杉矶分校的科学家将参与当地和全国的协同活动，包括专业项目和K-12教育和推广。
