This project transforms an established, state-of-the-art, high-throughput, geologic dating laboratory at the University of Vermont into a national facility open for use by the broader science community. It will provide both intellectual resources and a venue for consistent, reliable, high-quality, and safety-focused preparation of samples using a hands-on model that integrates research and research training. Over the past several decades, the use of these nuclides in Earth Science has increased rapidly; however, sample preparation remains tedious, difficult, and hazardous, requiring strong acids and complicated and expensive clean laboratory facilities and expertise that are not readily available. The approach of this facility is cost-effective because it relies on existing physical and intellectual infrastructure and builds on demonstrated research and research training successes. Working closely with experts, the facility staff will broaden participation and build long-term relationships by proactively engaging students, faculty, and administrators at both undergraduate institutions and graduate institutions serving communities underrepresented in STEM. The facility will use collaborative outreach activities including campus visits and a seed grant program to bring minority students and their faculty mentors to the laboratoryThis is a new approach aimed at broadening participation in the rapidly expanding field of cosmogenic isotope geoscience by opening a successful cosmogenic geochemistry laboratory to the broader community. Building upon tested sample-processing and training protocols, we will facilitate research and research training by increasing access to 10Be and 26Al sample preparation. Because of limited laboratory availability, the cosmogenic nuclide community has remained small. Providing a national sample preparation facility will catalyze the inclusion of new and different scientists, increasing the number and diversity of projects involving these isotopes - a catalyst for transformative research. Supporting a community facility for sample processing and research training has numerous different broader impacts. 1) It directly addresses a current bottleneck in cosmogenic nuclide studies: the extraction of 10Be and 26Al from rock, soil, and sediment that precedes isotopic measurement. 2) It broadens participation by providing open access to a state-of-the-art processing facility for the many students and faculty who do not have such a facility at their home institutions. 3) The outreach program, supported by the experience of Semken and Whittaker, goes directly to faculty and students at institutions serving minority communities and the seed grant program brings faculty/student teams from Historically Black Colleges and Universities as well as Tribal Colleges to the laboratory for meaningful collaboration and hands-on training. 4) Technician support will provide for research training in isotopic clean lab methods for students, researchers, faculty, and young investigators in a variety of geoscience disciplines through lab residencies, lab consultancies, a yearly training course for those wishing to adopt these methods or start a similar laboratory.

该项目将佛蒙特大学的既定，最先进的高通量，地质约会实验室转变为一个国家设施，供广泛的科学界使用。它将既可以提供智力资源和一个场所，以使用整合研究和研究培训的动手模型来始终如一，可靠，高质量和以安全为重点的样品。在过去的几十年中，这些核心在地球科学中的使用迅速增加。但是，样品制备仍然乏味，困难和危险，需要强酸，复杂且昂贵的清洁实验室设施以及不容易获得的专业知识。该设施的方法具有成本效益，因为它依赖于现有的物理和智力基础设施，并以展示的研究和研究培训成功为基础。与专家紧密合作，设施人员将扩大参与并建立长期的关系，以积极吸引本科机构的学生，教职员工和管理人员，以及为STEM中代表性不足的社区提供服务的研究生机构。该设施将使用包括校园访问和种子赠款计划在内的合作推广活动，将少数群体及其教职员导师带到实验室，这是一种新方法，旨在通过开放一个成功的宇宙同位素地球科学领域来扩大参与的参与，从而成功地开设了一个成功的宇宙宇宙基础地球化学实验室对更广阔的社区。在经过测试的样本处理和培训方案的基础上，我们将通过增加对10BE和26AL样本准备的访问来促进研究和研究培训。由于实验室的可用性有限，宇宙核素社区仍然很小。提供全国样本准备设施将催化新的和不同的科学家的包含，增加涉及这些同位素的项目的数量和多样性，这是变革性研究的催化剂。支持社区设施进行样本处理和研究培训具有许多不同的广泛影响。 1）它直接解决了宇宙核素研究中的当前瓶颈：从同位素测量之前的岩石，土壤和沉积物中提取10BE和26AL。 2）它通过为许多在其家庭机构没有这样的设施的学生和教职员工提供开放访问最先进的处理设施，从而扩大了参与。 3）在Semken和Whittaker的经验的支持下，外展计划直接向服务少数民族社区的机构的教师和学生提供，而SEED GRANT计划将来自历史悠久的黑人学院和部落大学的教师/学生团队带到了实验室，从事有意义的合作和动手培训。 4）技术人员的支持将为学生，研究人员，教职员工和年轻研究人员提供各种地球科学学科的研究培训，通过实验室居住，实验室咨询公司，年度培训课程，为希望采用这些方法或开始类似实验室的人提供年度培训课程。
