Technician support for the Yale (U-Th)/He chronometry facility

（U-Th）/He测时法的使用在过去几年中得到了显著的扩展，主要是在构造和地貌问题中应用于限制地壳浅部折返的时间和速率。耶鲁大学他约会实验室支持许多这些项目，无论是内部和外部的部门，涉及学生和其他研究人员。此外，该实验室还进行了He测年的实验开发和创新应用，进行了必要的实验，以便在新阶段使用该技术，改进分析方法，并将He测年应用于广泛的问题，如浅层地壳中岩浆加热的动力学，碎屑研究和天然煤火。所有这些项目（以及行业ICP-MS的使用）都需要实验室经理/技术员在样品处理和用户培训方面提供支持。这笔资金将为耶鲁大学（U-Th）/He计时和部门ICP-MS设施的全职实验室经理/技术员（Stefan Nicolescu博士）提供部分支持。Nicolescu的职责包括用户培训、样品处理、设备维护和实验室规划/设计，以及与实验室相关的高分辨率ICP-MS的维护和用户培训。这种支持将通过提供以下支持促进研究、学习和基础设施方面的更广泛影响：a）为耶鲁大学和其他机构的学生和其他研究人员提供He测时和ICP-MS分析方面的访问、用户培训和经验; B）本科生/教师顾问暑期讲习班，内容涉及He测时、建模和各种应用中的解释; c）继续为Nicolescu提供专业发展和培训。***

EAR-0233767ReinersThe use of (U-Th)/He chronometry has expanded significantly in the last several years, primarily in applications involving constraints on the timing and rate of shallow-crustal exhumation as applied to tectonic and geomorphic problems. The Yale He dating lab supports many of these projects, both within and outside the department, involving students and other researchers. In addition, the lab also conducts both experimental development and innovative applications of He dating, performing experiments necessary for use of the technique on new phases, improved analytical methods, and applying He dating to a wide range of problems such as the dynamics of magmatic heating in the shallow crust, detrital studies, and natural coal fires. All of these projects (as well as use of the sector ICP-MS) require support from the lab manager/technician for sample processing and user training. This funding will provide partial support for a full-time lab manager/technician (Dr. Stefan Nicolescu) for the Yale (U-Th)/He chronometry and sector ICP-MS facilities. Nicolescu's responsibilities include user training, sample processing, equipment maintenance, and planning/design in the lab, as well as maintenance of and user-training on the high-resolution ICP-MS associated with the lab. This support will facilitate broader impacts in research, learning, and infrastructure by providing support for: a) access to, and user training and experience in, He chronometry and ICP-MS analysis for students and other researchers both at Yale and other institutions; b) undergraduate/faculty advisor summer workshops on He chronometry, modeling, and interpretations in a variety of applications; c) continued professional development and training for Nicolescu. ***
