This award partially supports a technician who plays a key role in the recently established, NSF-funded multiple collector inductively coupled plasma mass spectrometer (MC-ICP-MS) laboratory at the University of Illinois at Urbana-Champaign (UIUC). The laboratory will be used to make high-precision isotope ratio measurements, which are critical in NSF-supported research in several areas of Geology, Anthropology, and Environmental Chemistry at UIUC. Specific applications of the instrument include:- Tracing chemical reactions involving potentially toxic selenium, chromium, and mercury in ground water and surface water- Revealing the processes through which magmas are generated and migrate toward the Earth's surface- Determining the ages of past climate changes - Determining the ages of mountain-building events and the processes involved in them- Tracing migration of human ancestors and archaeological artifactsThe technician is essential for the proper operation and efficient use of this advanced, complex instrument and enables the laboratory to serve a large, diverse community of students and researchers. The educational impact of the laboratory is greatly enhanced by the technician's efforts. Students in three classes use the instrument with his help. These students and the many graduate students who use the instrument for thesis research learn key scientific practices as they collect data, assess its quality, and interpret first-hand results.

该奖项部分支持一名技术人员，该技术人员在最近由 NSF 资助的伊利诺伊大学厄巴纳-香槟分校 (UIUC) 建立的多收集器电感耦合等离子体质谱仪 (MC-ICP-MS) 实验室中发挥着关键作用。该实验室将用于进行高精度同位素比测量，这对于 UIUC 地质学、人类学和环境化学多个领域的 NSF 支持的研究至关重要。 该仪器的具体应用包括： - 追踪地下水和地表水中涉及潜在有毒的硒、铬和汞的化学反应 - 揭示岩浆产生和向地球表面迁移的过程 - 确定过去气候变化的年龄 -确定造山事件的年龄及其所涉及的过程 - 追踪人类祖先的迁徙和考古文物技术人员对于正确操作和有效使用这种先进、复杂的仪器至关重要，并使实验室能够为由学生和研究人员组成的大型、多元化社区。 实验室的教育影响因技术人员的努力而大大增强。 三个班的学生在他的帮助下使用了该乐器。 这些学生和许多使用该仪器进行论文研究的研究生在收集数据、评估数据质量和解释第一手结果时学习关键的科学实践。
