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）的性质是物理和STFC的关键优先级。在我们的银河系中直接检测Electroweak-Scale DM是XLZD财团的主要目标，该目标是由该领域最重要的合作组成的：Xenon-NT，Lux-Zeplin（LZ）和Darwin。 XLZD提出了一个基于领先的液体氙（LXE）技术的大型地下实验：对WIMP DM的确定搜索，能够排除或发现在不可减少中微子背景上方的可访问参数空间中。全世界600名作者签署的综合白皮书中详细介绍了这种“罕见事件天文台”的科学潜力。 LZ和Xenon-NT是目前领域的主要实验。在XLZD中发现DM将对我们对宇宙的理解，其出生和结构的理解具有深远的影响。STFC目前正在考虑在北约克郡Boulby Underground实验室的最先进的新设施中托管XLZD实验的提议（XLZD@Boulby）。液体氙气稀有活动天文台很可能是在布尔比（Boulby）举办的最大项目，并得到了访问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该设施设计。该项目建立了与地下和地面空间和设施配置以及与大型物品的运输和地下制造有关的学术和技术互动。此外，该项目开发了影响设施设计的更具挑战性的危害分析，并探讨了设施与实验之间的管理和治理接口。
