NSF Arizona AMS Laboratory: Research Programs and Operations

01154887月这笔赠款为位于图森的亚利桑那大学的美国国家科学基金会亚利桑那加速器质谱学(AMS)设施的运营提供持续的设施支持。亚利桑那州的AMS设施是美国学术机构的三个AMS设施之一，专门对各种基质进行放射性碳(14C)测年，包括木材、沉积物、天然水域、骨骼化石、珊瑚骨骼和化学沉淀物(即洞穴)。此外，该实验室还保持了分析其他宇宙成因核素的能力，包括用作重要地质过程示踪剂的10Be和129I。该设施通过为NSF资助的科学家提供AMS分析的补贴费率，为更广泛的美国地球科学界提供服务。该实验室支持广泛领域的研究，包括地质学、考古学、气象学、地理学、海洋学、大气科学、水文学和生物学。

0115488JullThis grant provides continued facility support for the operation of the NSF Arizona Accelerator Mass Spectrometry (AMS) Facility at the University of Arizona in Tucson. The Arizona AMS facility, one of three AMS facilities at U.S. academic institutions, specializes in radiocarbon (14C) dating of a variety of matrices including wood, sediments, natural waters, fossilized bone, coral skeletons and chemical precipitates (i.e. speleothems). In addition, this lab maintains the capability to analyze for other cosmogenic nuclides including 10Be and 129I for use as tracers of geologically important processes. This facility serves the broader U.S. geosciences community through the provision of subsidized rates for AMS analyses for NSF-funded scientists. This lab supports research in a broad array of fields including geology, archaeology, meteoritics, geography, oceanography, atmospheric sciences, hydrology and biology.***
