Bierman1464526 This grant will support 1.5-day workshop to held fall 2014 on the campus of UC-Irvine that will bring together experts that use Accelerator Mass Spectrometry (AMS) to determine the abundances AMS of cosmogenic nuclides 10Be and 26Al for application to geomorphic processes research. The workshop will focus on the possible use of new generation, lower voltage, highly automated, and far less costly AMS systems than have been traditionally used in the U.S. to date. It is envisioned that lower cost, low voltage (1 MeV) AMS systems will allow for high throughput cosmogenic nuclide analysis at modest cost enabling hundreds of measurements that can be used to characterize the probability distribution of isotope concentrations ? allowing greatly enhanced reliability for dating moraines, for isochron burial dating of sediments, and for tracing sediment across the landscape.

Bierman1464526 这笔赠款将支持 2014 年秋季在加州大学欧文分校举办的为期 1.5 天的研讨会，该研讨会将汇集使用加速器质谱 (AMS) 的专家，以确定宇宙成因核素 10Be 和 26Al 的 AMS 丰度，以应用于地貌过程研究。 该研讨会将重点讨论新一代、低电压、高度自动化且比美国迄今为止传统使用的成本低得多的 AMS 系统的可能使用。 预计成本较低的低压 (1 MeV) AMS 系统将能够以适中的成本进行高通量宇宙成因核素分析，从而实现数百次测量，这些测量可用于表征同位素浓度的概率分布？大大提高了冰碛年代测定、沉积物埋藏等时线年代测定以及整个景观中沉积物追踪的可靠性。
