项目摘要

This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). Gabriel Cecchini is awarded an NSF Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship to conduct a program of research and activities related to broadening participation by groups underrepresented in STEM. This fellowship to Dr. Cecchini supports his research project entitled "MPS-Ascend: Observation of the Positronium Plus Ion and Development of a Spin-Polarized Positron Beam for Angle-Resolved Positronium Emission Spectroscopy", under the mentorship of a sponsoring scientist. The host institution for the fellowship is the University of California Riverside (UCR) and the sponsoring scientist is Dr. Allen Mills.Cecchini will pursue a research project to create and observe, for the first time, the positronium plus ion (Ps+). The existence of this ion was originally predicted in 1946 and has yet to be observed in the laboratory. As a pure lepton system, Ps+ could be used in tests of quantum electrodynamics (QED). In addition, improvements in the positron source will enable the development of a new angle-resolved positronium emission spectrometer (ARPsES). Cecchini will mentor students in the positron lab at UCR, which is both a Hispanic Serving Institution and an Asian American, Native American, and Pacific Islanders Serving Institution. He will work with local high school teachers and students and will participate in conferences and assistance programs geared to recruitment, retention, and graduation of members of groups traditionally underrepresented in STEM such as the American Association for the Advancement of Science (AAAS), the Alliance for Graduate Education and the Professoriate (AGEP), and the Inclusive Graduate Education Network (IGEN).This 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.
该奖项全部或部分根据2021年美国救援计划法案(公法117-2)资助。 Gabriel Cecchini被授予NSF数学和物理科学博士后研究奖学金,以开展与扩大STEM中代表性不足的群体的参与有关的研究和活动计划。 Cecchini博士的奖学金支持他的研究项目,题为“MPS-Ascend:观察正电子素+离子和开发用于角分辨正电子素发射光谱的自旋极化正电子束”,在赞助科学家的指导下。该奖学金的主办机构是加州大学滨江分校(UCR),赞助科学家是艾伦·米尔斯博士。Cecchini将从事一项研究项目,首次创造和观察正电子素+离子(Ps+)。这种离子的存在最初是在1946年预测的,但尚未在实验室中观察到。作为一个纯轻子系统,Ps+可以用于量子电动力学(QED)的实验。此外,正电子源的改进将使新的角分辨正电子素发射光谱仪(ARPsES)的开发成为可能。 Cecchini将在UCR的正电子实验室指导学生,UCR既是一个西班牙裔服务机构,也是一个亚裔美国人、美洲原住民和太平洋岛民服务机构。 他将与当地高中教师和学生合作,并将参加会议和援助计划,这些计划旨在招募,保留和传统上在STEM中代表性不足的团体成员毕业,如美国科学促进会(AAAS),研究生教育联盟和教授(AGEP),该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
