The James Madison University Particle and Nuclear Physics (JMU-PNP) group's activities are aimed at developing a three dimensional picture of the nucleon in order to get a glimpse of the interacting quarks within a proton or neutron. Given the small size of a nucleon, roughly a millionth of a billionth of a meter, this is not a trivial task. The field requires specialized detectors, techniques, and software. The JMU-PNP group has an established track record in these areas. Through immersion in state of the art research in Intermediate Energy Nuclear Physics the PIs will provide an outstanding educational experience for undergraduate students at JMU. Working on the hardware, software, and big data challenges associated with this research constitutes an excellent teaching opportunity for undergraduate students and promotes science and education beyond the university. The JMU group is involved in experiments in Halls A, B, and C at Jefferson National Laboratory (JLAB). They are participating in planning, data taking and data analysis for experiments from the 12 GeV era. The foci of this research program will be: 1.) publishing the results of experiment E12-10-002 (one of the Hall C commissioning experiments) where the JMU group has taken the lead in the data analysis, 2.) planning and running of experiment E12-06-117 in Hall B, and 3.) the commissioning and running of the SuperBigBite spectrometer in Hall A. The JMU-PNP group will also participate in the Fermilab g-2 experiment, which holds the promise of uncovering physics beyond the Standard Model. The members of the JMU-PNP group will continue their instrumentation R&D work which includes designing and building voltage dividers and PMT testing for the SuperBigBite spectrometer in Hall A. They will also participate in developing a Hermetic Compact Photon Source for the experiments in Halls C&D at JLABThis award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

詹姆斯·麦迪逊大学粒子与核物理(JMU-PNP)小组的活动旨在开发核子的三维图像，以便一瞥质子或中子中相互作用的夸克。考虑到核子的小尺寸，大约是十亿分之一米，这不是一项微不足道的任务。该领域需要专门的探测器、技术和软件。JMU-PNP小组在这些领域有既定的记录。通过沉浸在中能核物理最先进的研究中，PIS将为JMU的本科生提供出色的教育体验。致力于解决与这项研究相关的硬件、软件和大数据挑战，为本科生提供了一个绝佳的教学机会，并促进了大学以外的科学和教育。JMU小组参与了杰斐逊国家实验室(JLAB)A、B和C厅的实验。他们正在参与12GeV时代的实验计划、数据获取和数据分析。这项研究计划的重点将是：1)公布JMU小组带头进行数据分析的实验E12-10-002(C厅调试实验之一)的结果，2.B厅E12-06-117实验的规划和运行，以及3.)位于A厅的SuperBigBite光谱仪的调试和运行JMU-PNP小组还将参加费米实验室g-2实验，该实验有望发现标准模型以外的物理。JMU-PNP小组的成员将继续他们的仪器研发工作，包括为A厅的SuperBigBite光谱仪设计和制造分压器和PMT测试。他们还将参与开发用于JLAB C&amp；D厅实验的密闭紧凑型光子源。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
