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得到了显著的扩展，主要应用于构造和地貌问题中涉及浅层地壳挖掘的时间和速率限制的应用。耶鲁大学约会实验室支持许多这样的项目，包括系内外的学生和其他研究人员。此外，实验室还开展了He定年的实验开发和创新应用，在新阶段进行了必要的实验，改进了分析方法，并将He定年应用于广泛的问题，如浅层地壳岩浆加热动力学，碎屑研究和天然煤火。所有这些项目（以及部门ICP-MS的使用）都需要实验室经理/技术人员对样品处理和用户培训的支持。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/技术人员（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，促进在研究、学习和基础设施方面产生更广泛的影响：a)为耶鲁大学和其他机构的学生和其他研究人员提供He计时和ICP-MS分析的访问、用户培训和经验；b)本科生/指导教师暑期研讨会，关于He计时、建模和各种应用中的解释；c) Nicolescu的持续职业发展和培训。＊＊＊

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. ***
