Development of an Optimized Electron Microprobe for Geochronologic and Trace Element Analysis

0004077威廉姆斯该奖项提供了一个新的，高分辨率，地质年代学电子微探针X射线分析仪的安装和运行在阿默斯特的马萨诸塞州大学地球科学系的开发部分资金支持。该项目涉及开发新的X射线光谱仪系统、电子枪和柱元件、新的自动化样品台硬件以及用于X射线绘图和定量分析的新软件，目的是提高微量元素分析精度和空间分辨率。新的仪器包将使一种新的年龄测定技术的应用能够解决复杂的变质省份的热年代学。新电子探针的开发将由马萨诸塞州大学和电子束仪器制造商合作进行，双方分担费用。

0004077Williams This award provides partial funding support for the development of a new, high-resolution, geochronological electron microprobe X-ray analyzer to be installed and operated in the Department of Geosciences at the University of Massachusetts, Amherst. The project involves development of new X-ray spectrometer systems, electron gun and column elements, new automated sample stage hardware, as well as new software for X-ray mapping and quantitative analysis aimed at improved trace element analytical precision and spatial resolution. The new instrumentation package will enable application of a new age-dating technique capable of resolving the complex thermochronology of metamorphic provinces. Development of the new electron microprobe will be a collaboration between the University of Massachusetts and a manufacturer of electron beam instruments, with both parties contributing cost sharing.***
