This award will provide funding to support four equipment-based upgrades at the Arizona Accelerator Mass Spectrometry (AMS) laboratory. The purpose of these requests is to support the research and educational role of the laboratory, as well as its service to other users. The Arizona AMS laboratory functions as a service, research and educational laboratory. A key component is providing educational opportunities to undergraduate and graduate students from around the country to learn AMS techniques. Many students who have benefited from these programs have gone on to start their own research with applications in AMS. The lab also provides key support to users, including interpretation and understanding of their results. The award will support equipment and related support for four majors areas of study: low-voltage AMS, Iodine-129 measurements, sample automation and dissolved inorganic (DIC) and organic carbon (DOC) in groundwaters. These areas all represent areas of emphasis that have been highlighted at recent AMS and Radiocarbon conferences. The development of AMS capabilities at lower energies can lead to development of smaller machines or new experimental approaches, as has already been demonstrated. Sample automation is vital for more rapid sample preparation, and the improvements to 129I, DIC and DOC measurement capability will directly impact Arizona's ability to serve the needs of our own research, and those of our users.

该合同将为亚利桑那加速器质谱（AMS）实验室的四个设备升级提供资金支持。这些请求的目的是支持实验室的研究和教育作用，以及它对其他用户的服务。亚利桑那AMS实验室是一个服务、研究和教育实验室。一个关键的组成部分是为来自全国各地的本科生和研究生提供学习AMS技术的教育机会。许多从这些项目中受益的学生已经开始了他们自己的研究，并应用了AMS。该实验室还为用户提供关键支持，包括对其结果的解释和理解。该奖项将支持四个主要研究领域的设备和相关支持：低压AMS，碘-129测量，样品自动化以及地下水中的溶解无机（DIC）和有机碳（DOC）。这些领域都是最近AMS和放射性碳会议强调的重点领域。正如已经证明的那样，低能量AMS能力的发展可以导致更小机器或新实验方法的发展。样品自动化对于更快速的样品制备至关重要，对129I， DIC和DOC测量能力的改进将直接影响亚利桑那州满足我们自己研究需求的能力，以及我们用户的需求。
