Cold atom devices for sensing and metrology are the closest to commercial exploitation. The science is for someapplications highly developed and offers unquestioned performance advantages in sensitivity and some steps have beenmade at making more compact systems. But for genuine and widespread applications substantial improvements need to bemade in size, weight and power ('SWAP') and ruggedness of these systems.The project SCORPIO is concerned with developing a component technology that forms the core of an optical lattice clock.The physics packaged that enables a magneto optical trap (MOT) of strontium atoms is the central component in whichmulti-stage cooling and lattice preparation provides the key elements for clock interrogation.Optical lattice clocks use transitions in neutral atoms as quantum frequency references to deliver timing at very high levels of accuracy. This project forms a key part of the development of a commercial strontium clock, using techniques developedin the creation of the world's most stable clocks.The project will support the nucleation of a leading industrial capability for such future atomics packages and chamberproducts, which will be UK based and also therefore benefit from non-ITAR status.Our consortium of 2 partners has all of the critical expertise required to prosecute this project. It is led by the highlyinnovative commercial partner MSL who have a proven track record in bringing novel, state of the art technology in highquality lasers to market. University of Birmingham is leading of the UK National Quantum Technology Hub in Sensors andMetrology, an £80M innovation project including 6 University and over 70 industry partners. As such it provides a number oftechnology development specialists with expertise in optical clocks, gravity sensors and simulation packages in addition tocivil engineering expertise in the use of gravity sensors for underground mapping and links to potential commercial endusers.By combining the vacuum technology with laser technology through to testing we will also be making unique steps towardsa significant step down in size, power and cost requirements of a future Sr based atomic clock.To-date these components have been developed in isolation. It is important, however, to develop systems that canintegrate whilst following a similar ruggedisation and miniaturisation activities. This collaborative programme will develop aclear supply chain of UK-based technology suitable for various applications ranging from satellite-free navigation, ultra-highprecision timing for financial trades and exceptionally-precise gravetometers for sub-surface detection.

用于传感和计量的冷原子装置最接近商业开发。对于某些应用来说，这门科学已经非常发达，在灵敏度方面提供了无可争议的性能优势，并且已经采取了一些措施来制造更紧凑的系统。但是为了真正的和广泛的应用，需要在尺寸上进行实质性的改进，SCORPIO项目致力于开发一种构成光晶格时钟核心的组件技术。实现锶原子磁光阱（MOT）的物理封装是其中的核心组件，阶段冷却和晶格准备为时钟询问提供了关键要素。2光学晶格时钟使用中性原子的跃迁作为量子频率参考，以非常高的精度提供定时。该项目是商业锶钟开发的关键部分，采用了世界上最稳定的时钟技术。该项目将支持这种未来原子封装和腔室产品的领先工业能力的形成，这将是英国的基础，因此也受益于非-ITAR状态。我们的2个合作伙伴的财团拥有执行该项目所需的所有关键专业知识。它由高度创新的商业合作伙伴MSL领导，MSL在将高质量激光器的最新技术推向市场方面有着良好的记录。伯明翰大学是英国国家量子技术中心传感器和计量的领导者，这是一个价值8000万英镑的创新项目，包括6所大学和70多个行业合作伙伴。因此，它提供了一批技术开发专家，他们在光学时钟、重力传感器和模拟软件包方面具有专业知识，此外还提供了将重力传感器用于地下测绘的土木工程专业知识，并与潜在的商业终端用户建立了联系。通过将真空技术与激光技术相结合，直至测试，我们还将采取独特的措施，大幅缩小规模，功率和成本要求的未来锶基原子钟。到目前为止，这些组件已被开发的隔离。然而，重要的是要开发能够集成的系统，同时遵循类似的加固和加固活动。这一合作计划将开发一个清晰的英国技术供应链，适用于各种应用，包括无卫星导航、金融交易的超高精度计时和用于地下探测的异常精确的重力仪。
