Acquisition of an electron microprobe

0112339 Brearley该赠款为新墨西哥州大学（UNM）的地球和行星科学系提供部分支持，用于购买用于岩石学和宇宙化学研究的新电子微探针（EMP）。 同时提交给NASA宇宙化学计划的配套提案也将得到资助，并与UNM配套资金一起，将允许该部门购买具有五个波长色散光谱仪和轻元素分析能力的最先进的EMP。 新的EMP将取代老化的JEOL 733 Superprobe（vintage '83），并将在UNM的电子微束分析设施内进行维护，该设施还拥有现代化的SEM和TEM，并配备了一名具有电子显微镜专业知识的全职研究助理。 该仪器将支持该部门内的广泛研究计划，并与附近的桑迪亚国家实验室的科学家合作，包括高压地幔相的岩石学研究，美国西南部前寒武纪构造的调查，陨石的低温地球化学和岩石学研究。 该工具还将支持大量活跃的研究生群体。

0112339BrearleyThis grant provides partial support to the Department of Earth and Planetary Sciences at the University of New Mexico (UNM) for the acquisition of a new electron microprobe (EMP) for petrologic and cosmochemical research. A companion proposal submitted concurrently to NASA's Cosmochemistry program will also be funded and together with UNM matching funds, will allow the department to purchase a state-of-the-art EMP with five wavelength dispersive spectrometers and light element analytical capabilities. The new EMP will replace an aging JEOL 733 Superprobe (vintage '83) and will be maintained within the Electron Microbeam Analysis Facility at UNM which also houses a modern SEM and TEM and is staffed by a full time research associate with expertise in electron microscopy. The instrument will support a wide range of research programs within the department and in collaboration with nearby scientists from Sandia National Laboratory including petrologic studies of high pressure mantle phases, investigations of the Precambrian tectonics of the southwest U.S., low temperature geochemistry and petrologic investigations of meteorites. The instrument will also support a large and active graduate student population.***
