标题： Opportunities at the Sanford Underground Research Facility

摘要： 圣安德鲁斯地下研究设施（SURF）已经作为国际设施运行了15年以上，致力于推进罕见过程物理领域的多学科地下科学研究，同时为其他学科的研究提供机会。 SURF实验室设施包括一个地表校园以及位于4850英尺水平（1490米，4300米水当量）的校园，这些校园容纳了一系列重要的物理实验，包括LUX-ZEPLIN（LZ）暗物质实验和MAJORANA演示器无中微子双β衰变实验。 CASPAR核天体物理加速器已完成第一阶段运行，并计划于2024年开始第二阶段运行。 SURF还是长基线中微子设施（LBNF）的所在地，该设施将主办国际深地下中微子实验（DUNE）。 SURF提供世界级的服务，包括超低本底环境、低本底分析能力，以及在设施内生产的电铸铜。 SURF正在准备增加地下实验室空间。 计划正在推进，在4850L（1485米，4100米水当量）上建设新的大型洞室（通常为100米长×20米宽×24米高），时间安排在下一代实验（约2030年）。 SURF计划利用现有的咨询和社区委员会，并与地下科学界合作，以指导未来实验室空间的规划。 显示英文摘要

摘要： The Sanford Underground Research Facility (SURF) has been operating for more than 15 years as an international facility dedicated to advancing compelling multidisciplinary underground scientific research in rare-process physics, as well as offering research opportunities in other disciplines. SURF laboratory facilities include a Surface Campus as well as campuses at the 4850-foot level (1490 m, 4300 m.w.e.) that host a range of significant physics experiments, including the LUX-ZEPLIN (LZ) dark matter experiment and the MAJORANA DEMONSTRATOR neutrinoless double-beta decay experiment. The CASPAR nuclear astrophysics accelerator completed the first phase of operation and is planning for the second phase beginning in 2024. SURF is also home to the Long-Baseline Neutrino Facility (LBNF) that will host the international Deep Underground Neutrino Experiment (DUNE). SURF offers world-class service, including an ultralow background environment, low-background assay capabilities, and electroformed copper is produced at the facility. SURF is preparing to increase underground laboratory space. Plans are advancing for construction of new large caverns (nominally 100m L x 20m W x 24m H) on the 4850L (1485 m, 4100 m.w.e.) on the timeframe of next generation experiments (~2030). SURF plans to leverage existing advisory and community committees as well as engage the underground science community to inform plans for future laboratory space.
