Upgrade of Rensselaer's Electron Microprobe System

9522764瓦克这笔赠款提供52,145美元，作为升级JELL733电子微探针的部分费用，其中包括一个基于PC的计算机控制系统、一个新的能量色散光谱仪的BE窗口、数字X射线成像软件和两个用于波长色散分析的晶体。此次升级将使这些PI能够继续并提高其高质量，这是一项在火成岩和变质岩石学方面往往具有创新性的研究，对这些研究来说，其电磁脉冲的分析能力是至关重要的。具体地说，升级将有助于提高对光元素进行现场分析和生成二维元素分布图的能力。***

9522764 Wark This grant provides $52,145 as partial support of the costs of upgrading a JEOL 733 electron microprobe (EMP) with a PC-based computer control system, a new Be window for the energy dispersive spectrometer, digital X-ray imaging software and two crystals for wavelength dispersive analyses. This upgrade will allow these PI's to continue and improve their high quality an often innovative research in igneous and metamorphic petrology, for which the analytical capabilities of their EMP is of fundamental importance. Specifically, the upgrades will facilitate improved ability for spot analyses of light elements and generation of two- dimensional element distribution maps. ***
