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

(U-Th)/He计时法的使用在过去几年中有了显著的扩大，主要用于限制浅层地壳折返的时间和速度的应用，如应用于构造和地貌问题。耶鲁大学的何相亲实验室支持系内外的许多这样的项目，涉及学生和其他研究人员。此外，该实验室还进行了氦测年的实验开发和创新应用，进行了在新相上使用该技术所需的实验，改进了分析方法，并将氦测年应用于一系列问题，如浅层地壳岩浆加热的动力学、碎屑研究和天然煤火。所有这些项目(以及电感耦合等离子体质谱仪部门的使用)都需要实验室经理/技术员为样品处理和用户培训提供支持。这笔资金将为耶鲁大学(U-Th)/He天文台的一名全职实验室经理/技术员(Stefan Nicolescu博士)提供部分支持。Nicolescu的职责包括实验室的用户培训、样品处理、设备维护和规划/设计，以及与实验室相关的高分辨率电感耦合等离子体质谱仪的维护和用户培训。这种支持将促进研究、学习和基础设施方面的更广泛的影响，为以下方面提供支持：a)耶鲁大学和其他机构的学生和其他研究人员获得他的天文学和电感耦合等离子体质谱分析方面的用户培训和经验；b)关于他的天文学、建模和各种应用中的解释的本科生/教员暑期讲习班；c)为Nicolescu提供持续的专业发展和培训。***

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. ***
