This two-year grant will provide detection equipment to support an experimental program with radioactive nuclear beams (RNBs) at the National Superconducting Cyclotron Laboratory at Michigan State University (MSU) and at the recently upgraded low-energy facility at the University of Notre Dame(UND). Special arrays of silicon position- sensitive and fast-timing detectors will be used for a variety of cross-section measurements: total reaction and for neutron and proton removal, elastic scattering and inelastic scattering (including Coulomb excitation), and RNB transfer reactions and isomeric-beam induced reactions. Measurements of the 1- and 2- neutron removal cross sections from the neutron `halo` nuclei Li-11 and He-6 and He-8 and the proton `halo` nuclei N-12 and Ne-17 are particularly important. The detectors will be used in the focal plane of the S-800 Spectrometer at MSU and with the new double UM-UND superconducting solenoid system at UND. As part of the project, several specialized detectors will be developed in collaboration with US-based suppliers and DOE and NSF supported national laboratories. Several graduate and undergraduate students will participate in the research using these detectors. This grant is made possible by the support of the MPS Office of Multidisciplinary Activities equipment initiative.

这项为期两年的赠款将提供探测设备，以支持密歇根州立大学（MSU）国家超导回旋加速器实验室和圣母大学（UND）最近升级的低能设施的放射性核束（RNB）实验计划。 硅位置敏感和快速定时探测器的特殊阵列将用于各种截面测量：总反应和中子和质子去除，弹性散射和非弹性散射（包括库仑激发），RNB转移反应和异构束诱导反应。 测量中子晕核Li-11和He-6和He-8以及质子晕核N-12和Ne-17的1-和2-中子去除截面是特别重要的。 探测器将用于密歇根州立大学S-800光谱仪的焦平面，并与UND的新双UM-UND超导螺线管系统一起使用。 作为该项目的一部分，将与美国供应商以及DOE和NSF支持的国家实验室合作开发几种专业探测器。 一些研究生和本科生将使用这些探测器参与研究。 这项赠款是在MPS多学科活动办公室设备倡议的支持下实现的。
