The major goal of subatomic physics is understanding the structure of the nucleon. The structure can determined by scattering proton, electron, or neutrino probes from nucleons. Each probe is sensitive to different aspects of the nucleon structure. By varying the energy of the probe, the structure can be determined at different length scales. The objectives of this project are to measure the structure of the nucleon at distances from about 10% of the nucleon size up to the size of the nucleon. In addition, the characteristics of neutrino interactions with various nuclei will be determined with the MINERvA experiment. The results of these measurements are an important ingredient for other experiments which aim to understand the properties of neutrinos.Besides the scientific impact, this work will serve to train both undergraduate and graduate students, as well as post-doctoral students, in the methods of scientific research. This training in fundamental research provides a strong basis for careers in and outside of physics. Our students and post-docs have successfully moved to varied careers in medical physics, homeland security, and finance, as well as continuing in fundamental research.

亚原子物理学的主要目标是了解核子的结构。 这种结构可以通过从核子散射质子、电子或中微子探针来确定。 每个探针对核子结构的不同方面都很敏感。 通过改变探针的能量，可以在不同的长度尺度下确定结构。 这个项目的目标是测量核子结构的距离从核子大小的10%到核子大小。 此外，中微子与各种原子核相互作用的特征将通过MINERvA实验确定。 这些测量结果是其他旨在了解中微子性质的实验的重要组成部分。除了科学影响外，这项工作还将有助于培养本科生和研究生以及博士后研究生的科学研究方法。 这种基础研究培训为物理学内外的职业生涯提供了坚实的基础。 我们的学生和博士后已经成功地转移到医学物理，国土安全和金融，以及继续在基础研究的各种职业。
