9520504 Frey The Neutron Activation Laboratory in the Department of Earth, Atmospheric and Planetary Sciences (EAPS) at MIT is a facility dedicated to the analysis of natural materials, principally terrestrial rocks and minerals. The instrumentation of this facility has been incrementally updated, most recently in 1990, with the financial support of NSF and MIT. This facility is used for the NSF-sponsored geochemical research of Frey and colleagues and by a diverse group of other U.S. scientists, including faculty and students from other universities in the northeast and is highly regarded by peers. This grant provides $29,730 as partial support of the costs of replacing two semi-conductor detectors which were purchased in 1979 and are at the end of their useful life. These detectors along with ancillary electronics including high voltage supplies, amplifiers and analog to digital converters (ADC's) will aid in improved precision as well as guaranteeing the continuance of this facility's successful operation and service to the geochemical community. ***

小行星9520504 麻省理工学院地球、大气和行星科学系的中子活化实验室是一个致力于分析天然材料的设施，主要是陆地岩石和矿物。在国家科学基金会和麻省理工学院的财政支助下，该设施的仪器已逐步更新，最近一次更新是在1990年。该设施用于NSF赞助的Frey及其同事的地球化学研究，以及其他美国科学家的各种团体，包括东北部其他大学的教师和学生，并受到同行的高度评价。这笔赠款提供29 730美元，作为更换两台半导体探测器的部分费用，这两台探测器是1979年购买的，使用寿命已到。 这些探测器沿着辅助电子设备，包括高压电源、放大器和模数转换器（ADC），将有助于提高精度，并保证该设施的持续成功运行和为地球化学界提供服务。 ***
