Upgrade of the University of Alabama JEOL 8600 Electron Probe Microanalyzer

0744467 Stowell该拨款支持亚拉巴马大学（UA）地质科学系现有电子微探针（EMP）的升级。 现有的JEOL 8600 EMP（1990年）将配置一个新的基于PC的数据分析和成像系统，光谱仪中目前退化的衍射晶体将被取代，从而实现更高精度的微量化学分析和更快的分析时间。 升级后的EMP将支持一系列NSF资助的研究，涵盖变质岩石学，古气候学，地质年代学和碳酸盐岩学领域，并将振兴美国东南部的重要研究培训和分析设施。

0744467StowellThis grant supports upgrade of an existing electron microprobe (EMP) in the Department of Geological Sciences at the University of Alabama (UA). An existing JEOL 8600 EMP (vintage 1990) will be configured with a new PC-based data analysis and imaging system and current degraded diffraction crystals in the spectrometers will be replaced allowing for higher precision microchemical analysis and faster analysis times. The upgraded EMP will support a range of NSF funded research spanning the fields of metamorphic petrology, paleoclimatology, geochronology and carbonate petrology and will invigorate an important research training and analytical facility in the southeastern U.S.***
