Discovering the nature of particle dark matter (DM) is a key priority in Physics - and for STFC. Direct detection of electroweak-scale DM in our galaxy is the primary goal of the XLZD consortium, formed by the coming together of the foremost collaborations in the field: XENON-nT, LUX-ZEPLIN (LZ) and DARWIN. XLZD is proposing a large underground experiment based on the leading liquid xenon (LXe) technology: the definitive search for WIMP DM, able to rule out or discover in the accessible parameter space remaining above the irreducible neutrino background. The scientific potential of such a "rare event observatory" is detailed in a comprehensive white paper signed by 600 authors worldwide. LZ and Xenon-nT are the leading experiments in the field at present. Discovery of DM at XLZD would have profound implications for our understanding of the universe, its birth and its structure.STFC is currently considering a proposal to host the XLZD experiment in a state-of-the-art new facility at the Boulby Underground Laboratory in North Yorkshire (XLZD@Boulby). A liquid xenon rare event observatory might well be the largest project hosted at Boulby, supported by the largest international collaboration visiting the facility, and hence it would drive the facility design to a significant degree. This project sets up the academic and technical interactions related to the configuration of underground and surface spaces and facilities, and to the transportation and underground manufacture of large items. Additionally, this project develops the more challenging hazard analyses that impact facility design, and it explores management and governance interfaces between the facility and the experiment.

发现粒子暗物质 (DM) 的本质是物理学界和 STFC 的首要任务。直接探测银河系中的弱电尺度 DM 是 XLZD 联盟的主要目标，该联盟由该领域最重要的合作伙伴组成：XENON-nT、LUX-ZEPLIN (LZ) 和 DARWIN。 XLZD 正在提议进行一项基于领先液氙 (LXe) 技术的大型地下实验：对 WIMP DM 的最终搜索，能够排除或发现保留在不可约中微子背景之上的可访问参数空间。全球 600 名作者签署的综合白皮书详细介绍了这种“罕见事件观测站”的科学潜力。 LZ和Xenon-nT是目前该领域的领先实验。在 XLZD 发现 DM 将对我们理解宇宙、宇宙的诞生和结构产生深远的影响。STFC 目前正在考虑在位于伯尔比地下实验室的最先进的新设施中举办 XLZD 实验的提议。北约克郡（XLZD@Boulby）。液态氙稀有事件观测站很可能是布尔比主持的最大项目，并得到了参观该设施的最大国际合作的支持，因此它将在很大程度上推动设施设计。该项目建立了与地下和地面空间和设施的配置以及大型物品的运输和地下制造相关的学术和技术互动。此外，该项目还开发了影响设施设计的更具挑战性的危害分析，并探索了设施与实验之间的管理和治理接口。
