This award will push the frontier of ultra-high-energy (UHE) neutrino astrophysics above 100 peta-electron-volts (PeV) with the Askaryan Radio Array (ARA) testbed at the South Pole Station, whose dataset is now large enough to enable either a discovery of the highest energy neutrinos ever detected or setting the world’s best constraints in this crucial energy regime. The study will continue operation of this testbed experiment, doubling the size of the dataset in the next three years, streamline neutrino searches in the growing ARA dataset, calibrate simulations of neutrino detectors using newly-detected cosmic ray air showers, and test next-generation data acquisition electronics in the South Pole environment. ARA serves as a platform for recruitment of young scientists into STEM fields, and the development of junior scientists to work on the next generation of UHE neutrino detectors. This group engages secondary-school, undergraduate and graduate students in innovative neutrino research, and will develop a new module for the Masterclass for high school students on big data strategies to search for rare events in large datasets, using data from ARA and from the IceCube Neutrino Observatory.The radio technique used by ARA allows astrophysics to extend to these UHE neutrinos. ARA is laying the groundwork for the radio component of the next generation of neutrino observatories. A neutrino observation from ARA will constrain the properties of any global population of sources of the highest energy cosmic rays, complementing cosmic ray experiments that sample only local sources at the highest energies. Any event detected would be the highest energy neutrino ever observed, cosmic or terrestrial, and be the first-ever detection of a neutrino via radio frequency emission. This would be a major event in the pursuit of UHE neutrinos, and would provide crucial information for the technical design of future facilities. This project advances the goals of the NSF Windows on the Universe Big Idea.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.

该奖项将在100个PETA-电子伏特（PEV）以上的超高能源（UHE）神经物理学的前沿，以及在南极站的Askaryan无线电阵列（ARA）测试床位，其数据集现在足够大，可以发现最高能量神经元的最高能量，或者在这个世界上最有能量的能量范围。这项研究将继续进行该测试实验的操作，在未来三年内将数据集的大小加倍，在不断增长的ARA数据集中进行了简化神经元搜索，使用新发现的宇宙射线空气淋浴器校准神经元探测器的模拟，并测试下一代数据采集数据采集数据。 ARA是将年轻科学家招募到STEM领域的平台，并发展了初级科学家，以致力于下一代UHE神经元探测器。该小组参与了创新神经研究的二级，本科和研究生，并将为高中生的大师班开发一个新的模块，该模块使用来自ARA和Icecube Neutmtrino Perservatory的数据中的大型数据策略来搜索稀有事件。 ARA正在为下一代神经元观测的无线电组件奠定基础。来自ARA的观察将限制最高能量宇宙射线来源的任何全球人群的性质，从而组成宇宙射线实验，这些实验仅采样最高能量的局部来源。任何检测到的事件都是有史以来观察到的最高能量神经元，宇宙或陆地是通过射频发射对神经元的首次检测。这将是追求UHE神经元的重大事件，并将为未来设施的技术设计提供关键信息。该项目促进了NSF Windows在宇宙大概念上的目标。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的审查标准来诚实地通过评估来诚实地支持。
