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

该奖项将为马萨诸塞大学阿姆赫斯特分校地球科学系安装和运行的新型高分辨率、地质年代电子微探针x射线分析仪的开发提供部分资金支持。该项目涉及开发新的x射线光谱仪系统、电子枪和色谱柱元件、新的自动化样品台硬件，以及用于x射线制图和定量分析的新软件，旨在提高微量元素的分析精度和空间分辨率。新的仪器套件将使新的年龄测年技术的应用能够解决复杂的变质省的热年代学。新型电子探针的开发将由马萨诸塞大学和电子束仪器制造商合作，双方共同承担成本

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.***
