标题： The GRAND@Auger Prototype for the Giant Radio Array for Neutrino Detection

摘要： 截至2025年初，GRAND合作组织运营着三个原型阵列：中国GRANDProto300、法国GRAND@Nançay和阿根廷GRAND@Auger。 GRAND@Auger原型是通过GRAND与皮埃尔·奥热合作组织之间的协议建立的，将十个奥热工程无线电阵列（AERA）站点重新用于GRAND探测单元。 这种配置为同时探测空气簇射提供了独特的机会，使得GRAND@Auger与已建立的皮埃尔·奥热探测器能够进行逐事件比较。 此类比较有助于对GRAND的探测原理和重建能力进行详细评估。 在本次贡献中，我们介绍了GRAND@Auger的调试情况和初步结果，包括银河系背景噪声的测量以及与皮埃尔·奥热天文台同时检测到的第一个自触发候选事件。 这两个结果强调了GRAND@Auger在推进GRAND项目和改进大规模超高能粒子无线电探测技术方面的作用。 显示英文摘要

摘要： As of early 2025, the GRAND Collaboration operates three prototype arrays: GRANDProto300 in China, GRAND@Nan\c{c}ay in France, and GRAND@Auger in Argentina. The GRAND@Auger prototype was established through an agreement between the GRAND and Pierre Auger Collaborations, repurposing ten Auger Engineering Radio Array (AERA) stations as GRAND detection units. This setup provides a unique opportunity for coincident air-shower detection, enabling direct event-by-event comparison between GRAND@Auger and the well-established Pierre Auger detectors. Such comparisons allow for a detailed assessment of the detection principle and reconstruction capabilities of GRAND. In this contribution, we present an overview of the commissioning and preliminary results of GRAND@Auger, including the measurement of the Galactic background noise and the detection of the first self-triggered candidate event in coincidence with the Pierre Auger Observatory. Both results underscore the role of GRAND@Auger in advancing the GRAND project and refining the techniques required for large-scale radio detection of ultra-high-energy particles.
