The Atom Interferometric Observatory and Network (AION) is a proposed research infrastructure for studies of dark matter and gravitational waves from cosmological and astrophysical sources in the highly relevant but currently inaccessible mid-frequency band. It will develop and demonstrate the necessary deployable and scalable quantum technology by constructing and operating 10m- and 100m-scale instruments, paving the way for a future km-scale facility as detailed in L. Badurina et al. JCAP 05(2020), 011 (2020).This proposal for the Capital Call 2022 is in direct support of the AION project, which was funded originally as part of the QTFP programme and is now considered to be a core STFC programme. AION also has strong direct connections to the MAGIS programme in the US.The equipment applied for in this proposal will be essential for developing the novel cold atom quantum technology required by the Atom Interferometry Observatory and Network (AION) project to (a) stabilise the initial atomic cloud position and velocity, (b) upgrade the transport and atom optics techniques using a high-power 532nm laser and increase the resilience of the main instrument, and (c) enhance the matter-wave interferometry by auxiliary optical interferometry. The developed technologies will be crucial not only for AION but for all future large-scale atom interferometers.STFC references:Grant Title: AION: A UK Atom Interferometer Observatory and NetworkGrant Title: Differential atom interferometry and velocity selection using the clock transition ofstrontium atoms for AION

原子干涉观测站和网络（AION）是一个拟议的研究基础设施，用于在高度相关但目前无法访问的中频段研究来自宇宙学和天体物理来源的暗物质和引力波。它将通过建造和运行 10m 和 100m 规模的仪器来开发和演示必要的可部署和可扩展的量子技术，为未来公里规模的设施铺平道路，如 L. Badurina 等人所述。 JCAP 05(2020)、011 (2020)。这项 2022 年资本募集提案是对 AION 项目的直接支持，该项目最初是作为 QTFP 计划的一部分提供资金，现在被认为是 STFC 的核心计划。 AION 还与美国的 MAGIS 计划有很强的直接联系。本提案中申请的设备对于开发原子干涉观测站和网络 (AION) 项目所需的新型冷原子量子技术至关重要，以 (a) 稳定初始原子云位置和速度，（b）使用高功率532nm激光器升级传输和原子光学技术并增加主仪器的弹性，以及（c）通过辅助光学干涉测量增强物质波干涉测量。所开发的技术不仅对于 AION，而且对于所有未来的大型原子干涉仪都至关重要。STFC 参考文献：授权名称：AION：英国原子干涉仪天文台和网络授权名称：使用锶原子时钟跃迁的微分原子干涉测量和速度选择永恒之塔
