This award supports a full-time laboratory technician for five years at the University of Texas at Arlington Luminescence Laboratory (UTALL). This technician will expand access to luminescence dating services for the broader Earth Science community, especially to undergraduate and graduate students. Twenty-five percent of the technician’s time is dedicated to student training, including students within PI Brown’s research group, as well as undergraduate and graduate students in his Geochronology course , and support to external visitors. The UTALL is a laboratory partner for the Advancing Geochronology Science, Spaces, and Systems (AGeS3) program, an NSF-funded initiative that provides micro-funding opportunities to pair graduate students and underrepresented individuals across the United States with geochronology laboratories. The UTALL houses several unique instruments that are unavailable elsewhere in the United States and are thus uniquely valuable to external visitors. The technician will also develop freely available software for luminescence thermochronology analysis for the broader scientific community; presently this type of analysis is only done at a few universities including UTA owing in part to a lack of software. PI Brown and the technician will demonstrate existing and developed software at the New World Luminescence Dating Workshop, an annual meeting of luminescence dating specialists, which they will host. Additionally, the technician would help maintain research facilities, develop more accessible data archiving practices, and engage in community outreach activities.The technician will enhance a variety of research projects at the UTALL, the majority of which involve novel luminescence measurements of sediment or bedrock samples. Most of these projects, 18 currently planned, include graduate students, many of whom will visit the UTALL, and PIs who are early career researchers. Results from these projects will include the first measurements of ventifact erosion rates, the first luminescence ages of hydrothermal explosion deposits in Yellowstone National Park, the first luminescence-based exhumation histories of tectonic blocks in Southern California, and the first use of luminescence measurements to constrain boulder comminution on hillslopes. Other projects will determine paleoseismic records along several fault strands globally and records of ice sheet retreat in Greenland and Antarctica. The UTALL also hosts several unique analytical capabilities. It is the only US luminescence dating laboratory with a focus on luminescence thermochronology, it hosts the only infrared photo-stimulated luminescence rock slab imaging device in the US, which is used to measure sunlight exposure ages or erosion rates of hard rock surfaces. UTALL will soon host the first hydrostatic pressure vessel to test signal resetting within a luminescence dating laboratory, which the technician will help maintain and run.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项为德克萨斯大学阿灵顿分校发光实验室（UTALL）的全日制实验室技术员提供了五年的支持。该技术人员将扩大对更广泛的地球科学界（尤其是本科生和研究生）的发光约会服务的访问。技术人员的25％是致力于学生培训的，包括Pi Brown研究小组中的学生，以及他的地球人工学课程的本科生和研究生，并为外部访客提供支持。 UTALL是前进的地球体学科学，空间和系统（AGES3）计划的实验室合作伙伴，该计划是NSF资助的计划，可为研究生和美国各地的代表性不足的人与地球人类学实验室配对微型资助的机会。 UTALL设有几种在美国其他地方无法使用的独特乐器，因此对外部访客具有独特的价值。技术还将为更广泛的科学界开发用于发光热量分析的免费可用软件；目前，这种类型的分析仅在一些大学（包括UTA）进行的部分进行，部分原因是缺乏软件。 Pi Brown和The Technicians将在新世界发光约会研讨会上演示现有的和开发的软件，这是他们将举办的发光年度年度会议。此外，技术将有助于维护研究设施，开发更容易访问的数据归档实践并从事社区外展活动。技术将增强UTALL的各种研究项目，其中大多数涉及新颖的沉积物或BedRock样品的发光测量。这些项目中的大多数目前有18个项目，包括研究生，其中许多将访问UTALL，以及早期职业研究人员的PI。这些项目的结果将包括对通心病的侵蚀率的首次测量，黄石国家公园中的水热爆炸沉积物的第一个发光时代，第一个基于发光的基于发光的基于发光的构造库存历史以及首次使用发光测量的发光测量来限制山坡上的巨石成分。其他项目将确定全球多个断层链的古质记录以及格陵兰和南极洲的冰盖撤退记录。 UTALL还具有多种独特的分析能力。它是美国唯一关注发光热量学的发光约会实验室，它是美国唯一的红外光刺激发光岩石板成像装置，该设备用于测量硬岩石表面的阳光暴露年龄或侵蚀率。 UTALL很快将举办第一个在发光约会实验室中测试信号重置的静水压力容器，该技术人员将帮助维持和运行。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛的影响审查标准通过评估而被认为是珍贵的支持。
