The Assay and Acquisition of Radiopure Materials (AARM) is a collaborative effort to improve the understanding of neutron backgrounds underground. This work aids physics experiments that probe fundamental questions such as the nature of neutrinos and the dark matter in the universe. AARM, which includes experts in low-background techniques and simulations of neutron interactions underground, as well as representatives from major dark matter and double beta decay experiments and from the geology and microbiology communities, has worked together over the last three years to better understand low radioactivity environments and exploit common resources. By organizing around common goals that would benefit from structured cooperation, AARM has succeeded in creating a forum for sharing information and advancing research goals, including new technologies for particle detection, simulation techniques, and material screening. This award will continue AARM's role as a central unifying force in the international underground community with these specific goals: 1. Development of community-wide simulation tools, 2. Confirmation of simulation physics models and cross sections relevant to underground science by comparing to data worldwide and supporting specific efforts in neutron benchmarking, 3. Establishment of a global materials database, and 4. Continuation of the successful integration workshops centered around simulation, material screening, and underground physics. Broader Impact: The proposed work will create cross collaboration infrastructure support for underground physics. It directly provides training of scientists in radiation-detection technologies and low-background techniques, which supplements the country's technical intelligence base, both inside and outside physics, providing students with multidisciplinary opportunities in astro, nuclear, and particle physics.

放射性纯材料的分析和获取（AARM）是一项合作努力，以提高对地下中子背景的理解。 这项工作有助于探索宇宙中中微子和暗物质等基本问题的物理实验。 AARM包括低背景技术和地下中子相互作用模拟方面的专家，以及来自主要暗物质和双β衰变实验以及地质学和微生物学界的代表，在过去三年中共同努力，以更好地了解低放射性环境和开发共同资源。通过围绕共同目标进行组织，这些目标将受益于结构化合作，AARM成功地创建了一个共享信息和推进研究目标的论坛，包括粒子探测、模拟技术和材料筛选的新技术。这个奖项将继续AARM的作用，作为一个中央统一的力量，在国际地下社会与这些具体目标：1。开发社区范围内的模拟工具，2。通过与世界范围内的数据进行比较，确认与地下科学相关的模拟物理模型和横截面，并支持中子基准测试方面的具体工作。建立全球材料数据库; 4.继续围绕模拟、材料筛选和地下物理成功的集成研讨会。更广泛的影响：拟议的工作将为地下物理学创建交叉协作基础设施支持。它直接为科学家提供辐射探测技术和低本底技术方面的培训，这补充了该国物理学内外的技术情报基础，为学生提供了天文学、核物理学和粒子物理学方面的多学科机会。
