The Mini-Fountain Cold Atom Clock project will design and demonstrate a compact physics package (cold-atom source, microwave cavity, vacuum system) for an atomic fountain clock that achieves similar performance to full-sized Primary Frequency Standards. The project will also use all-in-fibre control optics to improve the robustness and reliability of the device, while further serving to reduce size and complexity. This system will allow exceptional hold-over capability in the event of GNSS outage, as well as widening access to state-of-the-art microwave frequency stability.

微型喷泉冷原子钟项目将为原子喷泉钟设计和演示一个紧凑的物理包（冷原子源，微波腔，真空系统），实现与全尺寸主频率标准相似的性能。该项目还将使用全光纤控制光学器件来提高设备的鲁棒性和可靠性，同时进一步减小尺寸和复杂性。这一系统将允许在全球导航卫星系统中断的情况下具有特殊的保持能力，并扩大对最先进微波频率稳定性的利用。
