Technician Support for Isotope Geochemistry

9807951库尔茨这笔赠款为伍兹霍尔海洋研究所的同位素地球化学设施技术员(D.Lott先生)提供三年的部分工资支持。这是仪器和设施计划(地球科学)下的第一阶段技术支持补助金。洛特将在M.Kurz博士的监督下，负责与热电离和惰性气体质谱仪相关的维护、培训和技术支持。洛特在开发低温系统方面拥有丰富的经验，这是在质谱分析之前将惰性气体彼此分离所必需的。这个实验室具有出色的氦能力，但越来越专注于测量较重的惰性气体(Ar和Xe)。因此，除了培训研究生和监督实验室的日常运作外，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，并确保技术能力得到广泛应用。将受益的研究领域跨越了许多学科界限，从冰川沉积物的表面暴露年代到地幔地球化学。伍兹霍尔有一大群地球化学家，他们也将直接受益于技术支持。***

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. ***
