9406120 Frey This award provides partial funding for the support of a technician assigned to the operation and maintenance of the Neutron Activation Analysis Laboratory in the Department of Earth, Atmospheric, and Planetary Sciences at the Massachusetts Institute of Technology. The laboratory is a facility dedicated to the analysis of natural materials, principally terrestrial rocks and minerals. Gamma ray spectroscopy is used to determined the abundance of many trace elements, used as tracers to better understand the processes which have formed the Earth's crust and mantle. The instrumentation of the facility consists of semi- conductor detectors, multichannel analyzers, and computer control. The facility is used for sponsored geochemical research of the Principal Investigator and colleagues at MIT and by a diverse group of other U.S. scientists, including faculty and students from other universities and colleges, principally in the northeast. *** 9406684 Johnson This award provides partial funding for the support of a technician assigned to the Radiogenic Isotope Laboratory in the Department of Geology and Geophysics at the University of Wisconsin, Madison. The technician will assist in the operation and maintenance of the laboratory's equipment that includes a multicollector thermal ionization mass spectrometer and associated instrumentation for sample preparation and data analysis. The laboratory is a resource for mass spectrometric analysis needed in research and teaching projects in the earth sciences by a large number of researchers on-campus and off-campus. Research applications include work on Arctic Ocean sediments, mantle geochemistry, volcanism, geochronology of carbonates in the Michigan Basin and Wisconsin Arch provinces, and Archean and Proterozoic granites. The technician will also participate in the technical developmental work of the laboratory, including the development of new methods for the quantitative measurement of the iso topes of hafnium. ***

小行星9406120 该奖项提供了部分资金，用于支持一名技术人员，该技术人员被分配到马萨诸塞州理工学院地球、大气和行星科学系的中子活化分析实验室进行操作和维护。该实验室是一个专门用于分析天然材料的设施，主要是陆地岩石和矿物。伽马射线光谱学用于确定许多微量元素的丰度，用作示踪剂以更好地了解形成地壳和地幔的过程。 该设施的仪器包括半导体探测器、多通道分析器和计算机控制。该设施用于资助麻省理工学院的首席研究员和同事以及其他美国科学家的地球化学研究，包括来自其他大学和学院的教师和学生，主要是在东北部。 * 9406684约翰逊 该奖项提供部分资金，用于支助一名技术人员，该技术人员被派往威斯康星州麦迪逊的地质和地球物理系放射性同位素实验室。该技术员将协助操作和维护实验室设备，其中包括一台多接收器热电离质谱仪和用于样品制备和数据分析的相关仪器。该实验室是大量校内和校外研究人员在地球科学研究和教学项目中所需的质谱分析资源。研究应用包括北冰洋沉积物、地幔地球化学、火山作用、密歇根盆地和威斯康星州拱省的碳酸盐地质年代学以及太古代和元古代花岗岩。该技术员还将参与实验室的技术开发工作，包括开发定量测量铪同位素的新方法。 ***
