Physics (13)This project makes a major device, the Stony Brook Tandem Van de Graaff accelerator, accessible to students and educators through both on-site and remote access and allows its use for a wide variety of applications ranging from anthropology (using 14C dating techniques) through nuclear physics. Using video-conference-based tools, students have the opportunity to study nuclear collisions by taking virtual control of a functioning nuclear accelerator and its associated detectors. Among other experiments, students are able to conduct neutron threshold studies, observe resonance states in (p,n) reactions, study heavy-ion reactions, and perform discrete gamma ray experiments. Because the device is also able to make accelerator mass spectrometry measurements, the long-range facility plan is to perform 14C dating to determine the age of biological materials (currently available), detect 26Al (possibly associated with Alzheimer's disease), and measure 41Ca from bones, 36Cl from ice cores, ground water, and glacially-cleaved mountain tops, and 129I from fossil fuel reserves. While the primary focus of the current project is undergraduate education, the accelerator is also available to the pre-college and graduate communities.

物理学（13）该项目制造了一个主要装置，即斯托尼布鲁克串联货车德格拉夫加速器，使学生和教育工作者能够通过现场和远程访问使用，并使其能够用于从人类学（使用14 C测年技术）到核物理学的各种应用。 使用基于视频会议的工具，学生有机会通过虚拟控制功能核加速器及其相关探测器来研究核碰撞。 在其他实验中，学生能够进行中子阈值研究，观察（p，n）反应中的共振态，研究重离子反应，并进行离散伽马射线实验。 由于该设备还能够进行加速器质谱测量，因此远程设施计划执行14 C测年以确定生物材料的年龄（目前可用），检测26 Al（可能与阿尔茨海默病有关），并测量骨骼中的41 Ca，冰芯，地下水和冰川切割山顶中的36 Cl，以及化石燃料储备中的129 I。 虽然目前项目的主要重点是本科教育，但加速器也可用于大学预科和研究生社区。
