中文摘要
该合同为购买一个专门的铯溅射离子源提供部分资金,该离子源将安装在普渡大学的加速器质谱仪设施中。离子源将能够从装载在60个样品盒中的目标样品中产生高强度的铍、碳、铝、氯、钙和碘等元素的离子束。该设施以FN串列式范德格拉夫加速器为基础,安装了离子源后,将能够测量上述元素中极少量的宇宙成因同位素(例如碳14)。这些同位素已被证明是有用的示踪剂,并可用于确定各种天然样品的年龄,在这些样品中,它们的浓度非常低。
英文摘要
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.
