Acquisition of an X-Ray Diffractometer for Materials Characterization in Multidisciplinary Research and Training

0520870 WirthThis主要研究仪器（MRI）计划赠款支持在Macalester学院，本科院校的研究和研究培训的X射线衍射仪的收购。 新的XRD将促进和加强对古土壤、骨成岩过程、沉积物和考古文物来源以及地层对比的研究，所有这些都需要矿物相鉴定。 半导体薄膜的研究也将受益于晶体材料的结构分析。 将获得PANalytical PW 3040 XRD。 XRD将取代过时的XRD（1986年），后者不再受制造商或服务合同的支持，并且经常出现机械和电子问题。 新的XRD将补充Macalester Keck电子实验室现有的SEM和XRF。 Keck实验室由首席PI Karl Wirth管理，并拥有全职技术支持。 凯克实验室是多所大学和学院的区域分析设施，包括伊利诺伊州、圣克劳德、北达科他州-法戈、贝洛伊特学院、科罗拉多学院和卡尔顿学院。*

0520870WirthThis Major Research Instrumentation (MRI) Program grants supports acquisition of an x-ray diffractometer for research and research training at Macalester College, an undergraduate institution. Research on paleosols, bone diagenetic processes, sediment and archaeological artifact provenance, and stratigraphic correlation, all requiring mineral phase identification, would be facilitated and enhanced with the new XRD. Research on semiconducting thin films would also benefit from structural analysis of crystalline materials. A PANalytical PW3040 XRD will be acquired. The XRD will replace an antiquated XRD (vintage 1986) that is no longer supported by the manufacture or a service contract and is experiencing frequent mechanical and electronics problems. The new XRD will complement an existing SEM and XRF in the Keck Electronics Lab at Macalester. The Keck lab is managed by the lead PI, Karl Wirth, and has full time technical support. The Keck lab serves as a regional analytical facility for multiple universities and colleges including, Illinois State, St. Cloud, North Dakota - Fargo, Beloit College, Colorado College and Carleton College.***
