0092508Elmore This award provides funding for the construction and testing of a new high-intensity cesium sputter ion source to be installed in the accelerator mass spectrometry (AMS) system at Purdue University. The new ion source is expected to improve the precision, detection limits and sample handling capacity of the Purdue AMS facility. The facility measures extremely small concentrations of 10Be, 14C, 26Al, 41Ca, 129I and other radionuclides that are used in research as tracers or in dating for a wide-range of research applications such as archeology and anthropology, paleoclimatology, landscape evolution, glaciology and paleoseismology.***

0092508Elmore该奖项为普渡大学加速器质谱（AMS）系统中安装的新型高强度铯溅射离子源的建造和测试提供资金。新的离子源有望提高普渡AMS设施的精度、检测限和样品处理能力。该设施测量极低浓度的10 Be、14 C、26 Al、41 Ca、129 I和其他放射性核素，这些核素在考古学和人类学、古气候学、景观演变、冰川学和古地震学等广泛的研究应用中用作示踪剂或测年。
