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

0520870Wirth这项主要研究仪器(MRI)计划拨款支持购买一台X射线衍射仪，用于在本科生机构Macalester学院进行研究和研究培训。新的X射线衍射仪将促进和加强对古土壤、骨骼成岩过程、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识别。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PANANACTIONAL PW3040 X射线衍射仪。X射线衍射仪将取代过时的X射线衍射仪(1986年款)，后者已不再受到制造或服务合同的支持，并经常遇到机械和电子问题。新的X射线衍射仪将补充位于Macalester的凯克电子实验室现有的扫描电子显微镜和XRF。Keck实验室由首席PI Karl Wirth管理，并有全职技术支持。凯克实验室是多所大学和学院的地区性分析设施，包括伊利诺伊州立大学、圣克劳德学院、北达科他-法戈学院、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.***
