An Automated High Intensity Ion Source for the AMS Facility at Purdue University

该奖项提供了部分资金用于收购一个 专门的铯溅射离子源将安装在 普渡大学的加速器质谱仪设备的 离子源将能够产生高强度的离子束， 铍、碳、铝、氯、钙等元素的离子 和来自装载在60个样本盒中的目标样本的碘。的 该设施是基于FN型串列货车德格拉夫加速器 并且，随着离子源的安装，将能够 测量宇宙成因同位素的极小浓度 (such例如碳-14）。这些 同位素已被证明是有用的示踪剂， 各种各样的天然样品， 在非常低的浓度水平。

This award provides partial funding for the acquisition of a specialized cesium sputter ion source to be installed in the accelerator mass spectrometry facility at Purdue University. The ion source will be capable of producing high-intensity beams of ions of the elements beryllium, carbon, aluminum, chlorine, calcium and iodine from target samples loaded in a 60-sample cassette. The facility is based on a model FN tandem Van de Graff accelerator and, with the installation of the ion source, will be capable of measuring extremely small concentrations of the cosmogenic isotopes (such as carbon-14, for example) of the above elements. These isotopes have proven useful as tracers and for determining the ages of a wide variety of natural samples in which they are incorporated at very low concentration levels.
