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.

该奖项将支持詹姆斯·麦迪逊大学的粒子和核物理小组，使其成为中能核物理最先进研究的关键贡献者，同时为本科生提供出色的教育体验。该小组的研究重点是探索物质、质子和中子的基本构件的结构。众所周知，质子和中子是由三个相互作用的夸克组成的，但产生和支配多夸克系统演化的机制还不完全清楚。该小组将通过散射质子和中子的光子来检测和分析产生的粒子来解决这个问题。该小组还参与了测量Muon的基本性质，这可以被认为是一个重电子。詹姆斯·麦迪逊大学的粒子和核物理小组在本科生参与研究方面有着良好的记录。这一奖项将为学生提供更多的教育机会，以及重要的外展活动，促进大学以外的科学和教育。该小组的成员是两项实验的发言人，这两项实验获准在杰斐逊实验室进行。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大厅CLAS12探测器运行的第二个物理实验。本提案期间的主要活动包括调试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获取和分析，以及在费米实验室安装和调试g-2探测器。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。这项工作在该小组位于詹姆斯·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。
