RUI: Probing Subatomic Physics Via Lepton Interactions

该奖项将支持詹姆斯麦迪逊大学的粒子和核物理小组，作为最先进的中间能量核物理研究的关键贡献者，同时为本科生提供杰出的教育经验。该小组的研究重点是探索物质的基本组成部分——质子和中子的结构。众所周知，质子和中子是由三个相互作用的夸克组成的，但产生和控制多夸克系统演化的机制尚不完全清楚。该小组将通过从质子和中子散射光子来检测和分析产生的粒子来解决这个问题。该小组还参与测量μ子的基本性质，μ子可以被认为是一个重电子。詹姆斯麦迪逊大学的粒子与核物理组在本科生参与研究方面有着良好的记录。该奖项将为学生提供更好的教育机会，以及重要的推广活动，促进大学以外的科学和教育。该小组的成员是经批准在杰斐逊实验室进行的两项实验的发言人。其中一项实验已确定，目前计划于2017年3月进行。该小组也是BONuS12实验的重要贡献者，该实验被确定为杰斐逊实验室的高优先级实验，目前计划作为使用b馆CLAS12探测器进行的第二个物理实验。本提案期间的主要活动包括调试由该小组为杰斐逊实验室建造的探测器，参与杰斐逊实验室各种实验的数据采集和分析。以及费米实验室g-2探测器的安装和调试。JMU-PNP小组的成员将继续他们的研发探测器工作，为未来的核物理实验做准备。这项工作在詹姆斯麦迪逊大学的实验室进行，将增强该小组在基于闪烁体的探测器和相关读出电子设备方面的能力和专业知识。

This award will support the Particle and Nuclear Physics group at James Madison University as a key contributor to state-of-the-art research in intermediate energy nuclear physics while providing an outstanding educational experience for undergraduate students. The group's research is focused on exploring the structure of the basic building blocks of matter, protons and neutrons. It is known that protons and neutrons are composed of three interacting quarks but the mechanisms that produce and govern the evolution of multi-quark systems are not fully understood. The group will address this by scattering photons from protons and neutrons to detect and analyze the resulting particles. The group is also involved in measuring fundamental properties of the muon, which can be thought of as a heavy electron. The Particle and Nuclear Physics group at James Madison University group has an established track record of strong undergraduate student involvement in research. This award will provide enhanced educational opportunities for students as well as significant outreach activities, promoting science and educating beyond the university. The members of the group are spokespersons on two experiments approved to run at Jefferson Lab. One of these experiments was identified is currently scheduled to run in March 2017. The group is also an important contributor to the BONuS12 experiment, which was identified as a high priority Jefferson Lab experiment, and is currently scheduled as the second physics experiment to run using the CLAS12 detector in Hall B. The main activities for the duration of this proposal include commissioning detectors built by the group for Jefferson Lab, participating in data taking and analysis for various Jefferson Lab experiments, as well as installation and commissioning of the g-2 detector at Fermilab. The members of the JMU-PNP group will continue their R&D detector work for future nuclear physics experiments. This work, carried out in the group's labs at James Madison University, will augment the group's capabilities and expertise in scintillator-based detectors and associated readout electronics.
