光学原子钟比最高性能的微波原子钟具有更好的稳定性和更低的系统不确定度。然而，性能最好的光学时钟在实验室环境中具有较大的占地面积，并且需要专业技能来保持连续操作。多个行业不断增长和不断变化的需求正在增加对这种能力级别的紧凑、坚固和便携式设备的需求。在本文中，我们讨论了一个紧凑的激光冷却88Sr+光学钟，进一步发展，将适合空间部署的物理包的设计。我们审查的设计参数，以目标在1018低部分的相对频率不确定度与此系统。然后，我们解释有限元建模的结果，以模拟离子阱和真空室的振动，冲击和热条件下，预计在发射和空间部署的响应。此外，静电模型已被开发来研究离子阱的几何公差和捕获效率之间的关系。我们提出了这些分析的结果，导致了一个更强大的原型设计准备进行实验测试。
Optical atomic clocks demonstrate a better stability and lower systematic uncertainty than the highest performance microwave atomic clocks. However, the best performing optical clocks have a large footprint in a laboratory environment and require specialist skills to maintain continuous operation. Growing and evolving needs across several sectors are increasing the demand for compact robust and portable devices at this capability level. In this paper we discuss the design of a physics package for a compact laser-cooled88Sr+optical clock that would, with further development, be suitable for space deployment. We review the design parameters to target a relative frequency uncertainty at the low parts in 1018with this system. We then explain the results of finite-element modelling to simulate the response of the ion trap and vacuum chamber to vibration, shock and thermal conditions expected during launch and space deployment. Additionally, an electrostatic model has been developed to investigate the relationship between the ion trap geometrical tolerances and the trapping efficiency. We present the results from these analyses that have led to the design of a more robust prototype ready for experimental testing.
