MPS-Ascend: High Altitude Filament Formation and Propagation

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。 Jessica Peña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。 Jessica Peña的奖学金支持一个名为“MPS-Ascend：高海拔细丝形成和传播”的研究项目，该项目由赞助科学家指导。该研究金的主办机构是中央佛罗里达大学，赞助科学家是Martin Richardson博士。具有足够峰值功率的超短脉冲激光器可以形成称为灯丝的自引导光学结构，通过形成等离子体通道，可以在地球大气层中的更远距离投射高强度。 Peña将定义各种大气压力和条件下的非线性或非线性状态，并描述环境因素如何影响长丝性能。 培尼亚将是学生的导师，以及与中央佛罗里达大学的研究和指导计划（RAMP），美国物理学会桥梁计划和全国创业板奖学金计划合作，从代表性不足的群体中招募和指导学生。该奖项由美国国家科学基金会地球科学理事会大气和地球空间科学处共同资助。该奖项反映了美国国家科学基金会的法定使命，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。

This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). Jessica Peña 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 Jessica Peña supports a research project entitled "MPS-Ascend: High Altitude Filament Formation and Propagation", under the mentorship of a sponsoring scientist. The host institution for the fellowship is the University of Central Florida and the sponsoring scientist is Dr. Martin Richardson. Ultra-short pulse lasers with sufficient peak power can form self-guiding optical structures called filaments that can project high intensities over kilometer-scale distances in the Earth’s atmosphere by forming plasma channels. Peña will define the nonlinear, or filamentation, regime for various atmospheric pressures and conditions as well as characterize how the filament properties are influenced by environmental factors. Peña will be a mentor to students, as well as work with the Research and Mentoring Program (RAMP) at the University of Central Florida, the American Physical Society Bridge program, and the GEM Fellowship program nationally to recruit and mentor students from underrepresented groups. This award is co-funded by the Division of Atmospheric and Geospace Sciences in the NSF Directorate for Geosciences.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.
