Acquisition of an Electron Probe Microanalyzer

该奖项将提供购买电子微探针所需资金的一半。这台新的电子显微镜将主要服务于印第安纳大学地质科学系的地质系教员和研究生的需要。印第安纳大学承诺提供额外的资金，使这次收购成为可能。七名地质系教师和他们的学生被确定为主要用户。其他六名教员希望减少使用频率或偶尔使用。这一大群教师和他们的学生从事不同领域的研究（例如，变质作用中机械和化学过程之间的热力学联系，各种类型的火山岩和火成岩的起源，陆地和月球沉积物的来源，晶体化学和玛瑙的带状）。这种新的微探针将取代已有19年历史的仪器，使其能够以更高的准确度和精密度进行元素微量分析。除了使用该仪器分析矿物和岩石外，预计校园和社区的材料科学研究人员将广泛使用该仪器。

This award will provide half of the funds needed for the acquisition of an electron microprobe. This new electron microscope will primarily serve the needs of the Geology faculty and graduate students in the Department of Geological Sciences at The University of Indiana. The University of Indiana is committed to provide the additional funds to make this acquisition possible. Seven Geology Department faculty and their students have been identified as primary users. Six other faculty expect to be less frequent or occasional users. This large group of faculty and their students pursue research in diverse areas (e.g. thermodynamic links between mechanical and chemical processes in metamorphism, origin of various types of volcanic and igneous rocks,provenance of terrestrial and lunar sediments, crystal chemistry and banding of agate). This new microprobe will replace a 19-year old instrument,and will now make it possible to do elemental micro- analyses with greater accuracy and precision. In addition to the use of this instrument to analyze minerals and rocks, wide use by materials science researchers on the campus and in the community is expected.
