WORKSHOP SUPPORT - Optimizing the next generation of AMS for measuring 10-Be and 26-Al

Bierman1464526这笔赠款将支持2014年秋季在加州大学欧文分校校园举办的为期1.5天的研讨会，届时将聚集使用加速器质谱学(AMS)确定宇宙成因核素10Be和26Al的丰度AMS的专家，用于地貌过程研究。研讨会将重点讨论新一代、低电压、高度自动化、成本远低于美国迄今传统使用的AMS系统的可能使用。据设想，低成本、低电压(1 MeV)的AMS系统将能够以适度的成本进行高通量的宇宙核素分析，从而能够进行数百次测量，这些测量可以用来表征同位素浓度的概率分布？极大地提高了冰雹测年、沉积物等时埋藏测年和全景沉积物追踪的可靠性。

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.
