0236617HermesThis grant supports the acquisition of a new wavelength-dispersive X-ray Fluorescence Spectrometer (XRF) to be installed in the XRF laboratory at the University of Rhode Island (URI), Department of Geosciences. The new instrument will replace the current non-functioning energy-dispersive system originally acquired in 1983. Upgrades and support for the 1983 instrument are no longer available from the company, and finally, in the summer of 2001, a "blown" X-ray tube that could not be replaced sealed its fate. The new state-of-the-art, wavelength-dispersive system will greatly improve the capabilities of our laboratory, including the ability to analyze for nearly all elements of geologic significance, at greatly improved sensitivities and accuracy. The University has provided a renovated laboratory for the new XRF. All sample preparation equipment, including crushers, grinders, fluxers, presses, etc. are in place as they were used with the 1983 instrument. Since 1983, the URI Geosciences XRF facility has served many scientists in the southern New England region, providing high-quality major and trace-element data for as many as one-hundred research projects. The facility supported a wide variety of basic research, 30-40 graduate theses, innumerable undergraduate theses and research projects , and provided an ongoing, long-term model for vertically integrated learning at URI. The URI Geosciences XRF facility not only enhances the research/education infrastructure of the university, but also provides a laboratory open to students and faculty at regional colleges and community colleges where sophisticated and expensive research laboratories are not available. We also have partnered with museums, the state Crime Laboratory, and other groups, all of which have substantial numbers of women in their organizations. The new equipment will permit the facility to continue to serve a diverse array of scientists and applications at URI as well as from the southern New England region.***

0236617 Hermes该赠款支持购买一台新的波长色散X射线荧光光谱仪（XRF），安装在罗得岛大学（URI）地球科学系的XRF实验室。 新仪器将取代1983年最初购置的现有的不起作用的能量分散系统。 该公司不再提供对1983年仪器的升级和支持，最终，在2001年夏天，一个无法更换的“爆炸”X射线管决定了它的命运。 新的最先进的波长色散系统将大大提高我们实验室的能力，包括分析几乎所有具有地质意义的元素的能力，大大提高了灵敏度和准确性。 该大学为新的XRF提供了一个经过翻新的实验室。 所有样品制备设备，包括破碎机、研磨机、助熔剂、压力机等，都已到位，因为它们与1983年仪器一起使用。自1983年以来，URI Geosciences的XRF设备为新英格兰南部地区的许多科学家提供服务，为多达100个研究项目提供高质量的主要和痕量元素数据。 该设施支持各种各样的基础研究，30-40研究生论文，无数的本科论文和研究项目，并提供了一个持续的，长期的模式，在URI的垂直整合学习。 URI Geosciences的XRF设备不仅增强了大学的研究/教育基础设施，而且还为地区学院和社区学院的学生和教师提供了一个开放的实验室，这些地方没有先进和昂贵的研究实验室。 我们还与博物馆、国家犯罪实验室和其他团体合作，所有这些组织都有大量妇女。 新设备将使该设施能够继续为URI以及南部新英格兰地区的各种科学家和应用程序提供服务。*
