This award funds the continued operation of the Askaryan Radio Array (ARA) experiment at the South Pole. ARA consists of five stations of antennas embedded up to 200m deep in the ice that are designed to detect radio “Askaryan” emission from neutrinos interacting in the ice. ARA’s dataset is the world’s most sensitive to ultra-high energy neutrinos from astrophysical sources. ARA has the potential to make a first discovery of UHE neutrinos, which are key to answering the century-old question of the origin of high energy cosmic rays. This award also funds the development of next-generation electronics, which will enable the identification of the radio emission with any of the variety of signatures brought about by complex properties of the ice that have been observed by ARA. This award also funds ARA’s broader impacts activities. ARA will continue to engage secondary-school, undergraduate, and graduate students in its cutting-edge research.This award funds continued operations and data taking for the Askaryan Radio Array (ARA), a neutrino astrophysics experiment with world-leading sensitivity to ultra-high energy (UHE, 10^17 eV) neutrinos expected from astrophysical sources and cosmic-ray induced cosmogenic interactions. ARA has the potential to make a first discovery of UHE neutrinos over the term of this award, which would be the highest energy neutrinos ever observed, provide a first glimpse of the universe at cosmic distances in this energy regime, and be the first observation of interactions at higher center-of-mass energies than those produced the LHC. This award will also enable the development of the new ARA-Next triggering system, a multi-channel triggering system based on the state-of-the-art Radio Frequency System on a Chip (RFSoC). ARA-Next would increase ARA’s sensitivity to unique signatures of radio emission from neutrino interactions that are expected based on ARA’s measurements of radio impulses in the South Pole ice. This award also funds ARA’s broader impacts activities. ARA will continue to engage secondary-school, undergraduate, and graduate students in its cutting-edge research. In addition, ARA will develop a new IceCube Masterclass program where high school students will learn about identifying signatures of UHE neutrinos by identifying the same signatures as ARA-Next. The program will serve as a pipeline for students who will themselves contribute to ARA research as undergraduates.The award is aligned with the NSF Big Idea of Windows on the Universe: the Era of Multi-messenger Astrophysics as it coordinates the use of multi-messenger observations utilizing potentially the highest energy neutrinos ever detected which might arise from the universe's highest energy cosmic sources of particles.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.

该奖项为南极的Askaryan无线电阵列（ARA）实验的持续运营提供了资金。 ARA由嵌入到冰中深度高达200m的天线的五个站组成，这些天线旨在检测冰中神经元的无线电“ Askaryan”发射。 ARA的数据集是来自天体物理学来源的超高能量神经元的世界最敏感的。 ARA有可能首先发现UHE神经元，这是回答高能量宇宙射线起源的百年历史的关键。该奖项还为下一代电子产品的发展提供了资金，该奖项将使无线电排放识别，并通过ARA观察到的冰的复杂特性带来的任何种类的签名。该奖项还资助了ARA的广泛影响活动。 ARA将继续参与其尖端研究中的中学，本科和研究生。这项奖项资金继续进行Askaryan无线电阵列（ARA）的数据，这是一个神经元素射流物理学实验，具有对超高能量的世界领先的敏感性（uhe，10^17 ev）的神经元，可从天体式和cosmic cosmic cosmic-cosmic-cosmic-ray cosmic-ray互动。 ARA有可能在该奖项的任期内首次发现UHE神经元，这将是有史以来观察到的最高能量神经元，它在该能量方面对宇宙距离的宇宙进行了首次瞥见，并且是比LHC产生的较高的质量能量的相互作用的首次观察。该奖项还将实现新的ARA-NEXT触发系统的开发，这是一种基于芯片上最新的射频系统（RFSOC）的多通道触发系统。 ARA-NEXT将增加ARA对无线电排放符号的敏感性。根据ARA对南极冰中无线电冲动的测量，预期的神经元相互作用。该奖项还资助了ARA的广泛影响活动。 ARA将继续参与二级，本科生和研究生的尖端研究。此外，ARA将开发一项新的ICECUBE大师班计划，高中生将通过识别与ARA-Next相同的签名来学习识别UHE神经元的签名。该计划将作为本科生将为ARA研究做出贡献的学生提供管道。该奖项与NSF的宇宙中的NSF大概念一致：多余的天体物理学时代，因为它可以协调使用潜在的能量的最高能量，从而协调多原子仪的使用，从而可以依赖于最高能量的能量，从而可以参与其中的最高能量。 NSF的法定使命，并通过评估诚实地认为，使用基金会的知识分子优点和更广泛的影响审查标准。
