Assay and Acquisition of Radiopure Materials

明尼苏达大学的这一提案要求为无线电纯材料分析和获取设施（或FAARM）的设计提供资金，该设施将包括一个位于4850英尺的专用防水室。该奖项将通过一项合作协议资助明尼苏达大学双城分校及其合作者为在DUSEL建造的这种设施提供初步设计，用于需要极低背景的实验。放射性纯物质的分析和获取对于DUSEL的广泛实验的成功至关重要，因此必须包括低本底计数设施。这项工作本身就具有广泛的影响力，因为它创建了筛选基础设施，可供罕见事件搜索社区以及其他科学领域使用-许多都是普遍感兴趣的，如国家安全，考古学，公共卫生和环境监测。此外，它还将为科学家提供辐射探测技术和低本底技术方面的培训，以补充该国在物理学内外的技术情报基础。

This proposal, from the University of Minnesota, requests funds for the design of a Facility for the Assay and Acquisition of Radio pure Materials (or FAARM), which is to include a dedicated, water-shielded room located at the 4850 ft. level, housed in a standard lab module (20m by 20m by 50 to 75m).The award, through a Cooperative Agreement, will fund the University of Minnesota in Twin Cities and collaborators to produce a Preliminary Design for such a facility to be constructed at DUSEL for experiments requiring extremely low backgrounds. Assay and acquisition of radio pure materials is essential to the success of a wide range of experiments at DUSEL, which therefore must include a low background counting facility. This work is inherently broad in impact, in that it creates screening infrastructure for use by both the rare event search community, as well as other scientific fields - many of general interest, such as national security, archaeology, public health, and environmental monitoring. Also, it will provide training of scientists in radiation-detection technologies and low-background techniques, which supplement the country's technical intelligence base, both inside and outside physics.
