Acquisition of a Scanning Electron Microscope

9816264 McKeegan这笔赠款为购买最先进的自动扫描电子显微镜(SEM)提供部分支持，以支持加州大学洛杉矶分校正在进行的离子微探针(IMP)研究。加州大学洛杉矶分校的IMP实验室是一个国家多用户设施，它通过地球科学部的仪器和设施部(IF)计划(EAR9806639)得到持续的支持，使全国和国际上的地球科学家能够使用大半径的Cameca 1270 IMP进行地面和地外样本的微型同位素研究。尤其是，加州大学洛杉矶分校的教员专门从事U/Pb锆石年代学(哈里森)、星际尘埃和球粒陨石中富钙铝包裹体的氧同位素研究(McKeegan)和年轻火山岩的U/Th系列测年(Reid)。

9816264McKeeganThis grant provides partial support of the costs of acquiring a state-of-the-art, automated scanning electron microscope (SEM) to support ongoing ion microprobe (IMP) research at UCLA. The UCLA IMP lab is operated as a national multi-user facility for which it receives on-going support through the Division of Earth Sciences' Instrumentation and Facilities (IF) program (EAR9806639) to allow geoscientists across the country and internationally, access to the large-radius Cameca 1270 IMP for microscale isotopic studies of terrestrial and extraterrestrial samples. In particular, faculty at UCLA specialize in U/Pb zircon geochronology (Harrison), oxygen isotopic studies of interplanetary dust and Ca-Al rich inclusions in chondrites (McKeegan) and U/Th series dating of young volcanics (Reid).***
