The National Science Foundation uses the Early-concept Grants for Exploratory Research (EAGER) funding mechanism to support exploratory work in its early stages on untested, but potentially transformative, research ideas or approaches. This EAGER project was awarded as a result of the invitation in the Dear Colleague Letter NSF 16-080 to proposers from Historically Black Colleges and Universities to submit proposals that would strengthen research capacity of faculty at the institution. The project at Hampton University aims to pursue the task of beam particle tracking with a Gas Electron Multiplier detector system for the MUon Scattering Experiment (MUSE) at the Paul-Scherrer Institute in Switzerland. The project outcome can have significant impact in the field of nuclear and particle physics and may lead to basic new knowledge in that field. Graduate students are involved in this activity.The Muon Scattering Experiment (MUSE) will provide key insights to the so-called proton radius puzzle - the seven-standard deviation discrepancy between proton charge radius measurements with electronic and muonic probes, respectively. Possible explanations also include new physics beyond the Standard Model. The MUSE experiment aims to address one of the most pressing questions in nuclear and particle science to date. MUSE uses mixed muon and electron beams of either charge to make precise measurements of the lepton-proton elastic scattering cross sections and proton form factors, with the goal to extract the proton charge radius for each probe. This requires precise measurements of the scattering angles necessitating the tracking of individual beam particles in a way not done before at low beam energies. This project focuses on the challenging task of high-resolution beam particle tracking at MUSE with Gas Electron Multiplier detectors in a high-rate environment.This project is co-funded by the Directorates for Education & Human Resources and Mathematical & Physical Sciences, as well as the Office of International Science and Engineering.

美国国家科学基金会使用早期概念探索性研究资助 (EAGER) 资助机制来支持早期阶段的探索性工作，涉及未经测试但具有潜在变革性的研究想法或方法。该 EAGER 项目的获奖是由于《亲爱的同事信 NSF 16-080》中邀请历史悠久的黑人学院和大学的提案者提交提案，以加强该机构教师的研究能力。汉普顿大学的该项目旨在利用气体电子倍增器探测器系统来完成瑞士 Paul-Scherrer 研究所 MUon 散射实验 (MUSE) 的束流粒子跟踪任务。该项目成果可能对核物理和粒子物理领域产生重大影响，并可能带来该领域的基本新知识。研究生参与了这项活动。μ子散射实验 (MUSE) 将为所谓的质子半径难题提供关键见解——电子探针和μ子探针分别测量质子电荷半径之间的七个标准偏差差异。可能的解释还包括标准模型之外的新物理学。 MUSE 实验旨在解决迄今为止核科学和粒子科学中最紧迫的问题之一。 MUSE 使用任一电荷的混合 μ 子束和电子束来精确测量轻子-质子弹性散射截面和质子形状因子，目的是提取每个探针的质子电荷半径。 这需要精确测量散射角，从而需要以以前在低光束能量下未完成的方式跟踪各个光束粒子。该项目重点关注 MUSE 在高速率环境下使用气体电子倍增器探测器进行高分辨率束粒子跟踪的挑战性任务。该项目由教育与人力资源理事会、数学与物理科学理事会以及国际科学与工程办公室共同资助。
