EAR-0447154SamsonThis award provides funds for a major upgrade of a JEOL 6300 Scanning Electron Microscope that was donated to the Department of Earth Sciences at Syracuse University by Chevron-Texaco. The instrument is equipped with an energy-dispersive detector (EDS) and three wave-length dispersive detectors (WDS) containing a total of six crystals. The upgrade will include (1) complete modern automation of the WDS system and associated data reduction and analysis, which will make the instrument essentially an electron microprobe and allow us to do a wide range of in situ microbeam X-ray analysis; (2) a new Digital Imaging System that will include direct beam control for fast back-scattered electron (BSE) and secondary electron (SE) imaging at 400 x 400 resolution and allow X-ray dot mapping with up to 16 channels, allowing us to make detailed, high-resolution X-ray maps of the elemental compositions of metamorphic minerals, such as garnet, or element zoning as indicators of different age domains in minerals such as monazite; (3) a new EDS System for X-Ray spectral identification of the elemental compositions of minerals that are imaged; and (4) cathodoluminescence (CL) imaging, that has become virtually routine in modern U-Pb geochronology laboratories in showing the internal complexities of zircon, such as zoning, core-overgrowth relationships, resorption, and a variety of other internal features. The requested upgrade will provide the Department of Earth Sciences with a truly modern analytical facility which will be made available to our students, those of other departments on our campus, and those of smaller institutions in Central New York.

EAR-0447154SAMSONSONTHIS奖为Chevron-Texaco捐赠给Syracuse University的地球科学系的JEOL 6300扫描电子显微镜提供资金。 该仪器配备了能量分散探测器（EDS）和三个波长度探测器（WDS），其中包含六个晶体。升级将包括（1）WDS系统的完整现代自动化以及相关的数据减少和分析，这将使仪器本质上是电子微型探针，并允许我们进行广泛的原位微孔X射线分析； （2）一种新的数字成像系统，该系统将包括以400 x 400分辨率的快速背部电子（BSE）和次级电子（BSE）和次级电子（SE）成像的直接控制，并允许X射线点映射多达16个频道，从而使我们可以制作详细的，高分辨率的，高分辨率的，高分辨率的X射线映射，例如，元素的元素元素（例如GarneNEN），例如GARNERENEN，例如GARNERENEN，或矿物质，例如独居石； （3）一个新的EDS系统，用于X射线光谱鉴定所成像的矿物质的元素组成； （4）在现代U-PB地球人工学实验室中几乎是常规的阴极发光（CL）成像，以显示锆石的内部复杂性，例如分区，核心过渡关系，吸收和其他内部特征。 要求的升级将为地球科学系提供真正的现代分析设施，该设施将为我们的学生，我们校园其他部门以及纽约中部较小机构的分析设施提供。
