项目摘要

9807951 Kurz This grant provides three years of partial salary support for the Isotope Geochemistry Facility technician at Woods Hole Oceanographic Institution (Mr. D. Lott). This is a phase I technician support grant under the Instrumentation and Facilities Program (Earth Sciences). Lott will have responsibility for maintenance, training, and technical support associated with the thermal ionization and noble gas mass spectrometers, under the supervision of Dr. M. Kurz. Lott has considerable experience in developing cryogenic systems that are necessary for separating the noble gases from one another prior to mass spectrometry. This laboratory has excellent capabilities for helium, but is increasingly focused on measurement of the heavier noble gases (Ar and Xe). Lott will therefore devote some of his effort to developing new methodologies for cryogenically separating the heavy noble gases, in addition to training of graduate students and supervision of day to day laboratory operations. His presence in the laboratory will insure that the instrumentation remains state-of-the-art, and that the technical capabilities are widely used. The areas of research, that will benefit, cross many disciplinary boundaries, ranging from surface exposure dating of glacial deposits to mantle geochemistry. There is a large community of geochemists at Woods Hole who will also directly benefit from the technical support. ***

Lott）。这是仪器和设施方案（地球科学）下的第一阶段技术人员支助赠款。洛特将负责维护，培训和与热电离和惰性气体质谱仪相关的技术支持，在M。库尔兹洛特在开发低温系统方面有相当丰富的经验，低温系统是在质谱分析之前将惰性气体彼此分离所必需的。该实验室具有出色的氦测量能力，但越来越多地专注于较重的惰性气体（Ar和Ar）的测量。因此，除了培训研究生和监督日常实验室操作外，洛特还将致力于开发低温分离重惰性气体的新方法。他在实验室的存在将确保仪器保持最先进的水平，并广泛使用的技术能力。研究领域，将受益，跨越许多学科的界限，从表面暴露的冰川沉积物的年龄地幔地球化学。伍兹霍尔有一个庞大的地球化学家社区，他们也将直接受益于技术支持。 ***
