This award will provide one-half the funding necessary to install a position-sensitive detector as a multiple collector in the ion microprobe operated in the Enrico Fermi Institute at the University of Chicago. The University of Chicago is committed to providing the remaining funds needed for the project. The installation of the new detector is estimated to result in a 50-fold increase in the efficiency with which the trace concentration of rare-earth elements can be measured. The PI, faculty colleagues and graduate students at Chicago make use of the ion microprobe for spatially resolved (on the order of tens of micrometers) analyses of trace elements and isotopes in rock, mineral and extraterrestrial samples. Their research is aimed at a better understanding of the origin of the solar system and the Earth.

该奖项将为芝加哥大学恩里科费米研究所的离子微探针安装一个位置敏感探测器作为多重收集器提供一半的资金。芝加哥大学承诺提供该项目所需的剩余资金。据估计，新探测器的安装将使测量痕量稀土元素浓度的效率提高50倍。芝加哥大学的PI、教员同事和研究生利用离子探针对岩石、矿物和外星样本中的微量元素和同位素进行空间分辨（在几十微米量级）分析。他们的研究旨在更好地了解太阳系和地球的起源。
