Cold atom devices for sensing and metrology are the closest to commercial exploitation. The science is for some applications highly developed and offers unquestioned performance advantages in sensitivity and some steps have been made at making more compact systems. But for genuine and widespread applications substantial improvements need to be made in size, weight and power ('SWAP') and ruggedness of these systems. The project SLATE is concerned with developing an optical lattice clock. The physics package that enables the trapping and probing of laser cooled atoms of strontium atoms is the central component 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 developed in 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 chamber products, 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 highly innovative commercial partner MSL who have a proven track record in bringing novel, state of the art technology in high quality lasers to market. University of Birmingham is leading of the UK National Quantum Technology Hub in Sensors and Metrology, an £80M innovation project including 6 University and over 70 industry partners. As such it provides a number of technology development specialists with expertise in optical clocks, gravity sensors and simulation packages in addition to civil engineering expertise in the use of gravity sensors for underground mapping and links to potential commercial end-users. By combining the vacuum technology with laser technology through to testing we will also be making unique steps towards a significant step down in size, power and cost requirements of any future Sr based atomic clock.To-date these components have been developed in isolation. It is important, however, to develop systems that can integrate whilst following a similar ruggedisation and miniaturisation activities. This collaborative programme will develop a clear supply chain of UK-based technology suitable for various applications ranging from satellite-free navigation, ultra-high precision timing for financial trades and exceptionally-precise gravetometers for sub-surface detection.

敏感性和计量学的冷原子设备最接近商业剥削。该科学适用于某些高度发达的应用程序，并在敏感性方面具有毫无疑问的性能优势，并且在制造更紧凑的系统方面已采取了一些步骤。但是，对于真正的和广泛的应用程序，需要对这些系统的大小，重量和功率（“交换”）和坚固性进行实质性改进。该项目Slate涉及开发光学晶格时钟。实现锶原子激光冷却原子的捕获和探测的物理包是时钟询问的中心部分。光学晶格时钟在中性原子中使用过渡作为量子频率参考，以在非常高的准确性时传递时间。该项目是使用在创建世界上最稳定时钟的技术中开发的，构成了商业锶时钟开发的关键部分。该项目将支持对这种未来的原子套餐和室内产品的领先工业能力的成核，这些工业能力将基于英国，因此也从非荷尔特人的身份中受益。2个合作伙伴的财团拥有起诉该项目所需的所有关键专业知识。它是由高度创新的商业合作伙伴MSL领导的，他们在将高质量激光器中的小说，最先进的技术推向市场方面具有良好的往绩。伯明翰大学是英国国家量子技术枢纽的传感器和计量枢纽，这是一个8000万英镑的创新项目，其中包括6个大学和70多个行业合作伙伴。因此，除了使用重力传感器用于地下映射以及与潜在的商业最终用户的链接的土木工程专业知识外，还为许多技术开发专家提供了光学时钟，重力传感器和仿真软件包方面的专业知识。通过将真空技术与激光技术结合到测试，我们还将迈出独特的步骤，以降低任何以后基于SR的原子时钟的大小，功率和成本要求，以隔离这些组件。但是，重要的是要开发可以在类似的坚固化和微型化活动的同时集成的系统。该协作计划将开发出一个基于英国的技术的清晰供应链，适用于各种应用程序，从无卫星导航，用于金融交易的超高精度时间和用于地下检测的异常专业的重力计。
