2020 Winners of 2020' Outstanding Science and Technology Achievement Prize of the Chinese Academy of Sciences 年中国科学院杰出科技成就奖获奖者 获 奖 集 体 Research Group of Space Cold Atom Clock in Tiangong-2 Shanghai Institute of Optics and Fine Mechanics , Chinese Academy of Sciences A fter more than twenty years of continuous efforts, the group proposed the technical roadmap of the space cold atom clock and made breakthroughs in a series of key technologies, such as the physics package operated for microgravity environment, the longterm autonomously-operating optical system used for the preparation and manipulation of cold atoms, the ultra-low-noise microwave synthesizer for cold atom clock, etc. Besides, the reliability problems to operate a cold atom clock in space were overcome. Based on the above-mentioned breakthroughs and innovations, the group developed the world-first space cold atom clock that had successfully been operating in orbit, demonstrated laser cooling of atoms and long-term continuous closed-loop operation of cold atom clock in orbit. The physics in cold atom clock was further studied and a frequency instability of 10 -16 was proved under microgravity. The space cold atom clock had been stably operating in orbit for almost three years and the mission was successfully accomplished. This achievement made China at the forefront of space-based cold atom sensors in the world and had a profound impact on future space researches based on cold atom technologies, benefiting the development of quantum physics and precision measurements. 空间冷原子钟环境试验现场 The space cold atom clock u nder environmental test 天宫二号空间冷原子钟研究集体 推荐单位：中国科学院上海光学精密机械研究所 研究集体主要科技贡献： 该研究集体经过二十多年不懈努力，提出了空间冷原子钟总体技术路线，突破了微 重力环境下运行的冷原子钟物理系统、长期自主运行的冷原子制备与操控光学系统 研究集体 Group photo 和冷原子钟超低噪声微波频率源等一系列关键技术，攻克了冷原子钟空间应用的可 靠性难题。基于上述突破与创新，研制了世界第一台在轨成功运行的空间冷原子钟， 首次在轨实现了激光冷却原子与冷原子钟长期闭环，深入研究了其中的物理规律， 验证了冷原子钟在轨天稳达到 10-16 量级的能力。空间冷原子钟在轨运行近三年，性 Outstanding contributors of this research group 能稳定，圆满完成预定任务，使我国在天基冷原子传感领域走在了世界前列，对未 Wang Yuzhu 来基于冷原子技术的空间科学研究有着深远影响，对量子物理及精密测量科学的发 Based on atomic clock and cold atom physics, he put forward a series of physical proposals for space cold atom clock operated under microgravity and confirmed the technical roadmap of the space cold atom clock in Tiangong-2 space laboratory. 空间冷原子钟的小型化光学系统 The miniaturized optical system for the space cold atom clock 展具有重大意义。 Liu Liang He analyzed the principal mechanism of space cold atom clock operated under microgravity and designed the physics package and the compact laser-cooling system of the space cold atom clock. 研究集体突出贡献者 Chen Weibiao 王育竹 中国科学院上海光学精密机械研究所 He confirmed the proposals of the laser sources, laser frequency stabilization unit and optical bench of the space cold atom clock in Tiangong-2 space laboratory and completed the design and verification of the reliability of the payload. 在轨获得的 Ramsey 条纹 Ramsey fringes obtained in orbit 主要科技贡献：在原子钟和冷原子物理的基础上，提出了在微重力 环境下冷原子钟的多种物理系统设计方案，并最终确定了天宫二号 空间冷原子钟的总体技术路线。 王育竹 Wang Yuzhu Major contributors Lü Desheng 刘 亮 中国科学院上海光学精密机械研究所 Li Tang Qu Qiuzhi Wang Bin Li Lin 刘 Song Dan Ren Wei Dong Zuoren Zhao Jianbo 空间冷原子钟研制现场 主要科技贡献：分析了冷原子钟在微重力环境下的运行机制，设计 了空间冷原子钟的物理系统和集成激光冷却装置。 空间冷原子钟的磁光阱 空间冷原子钟的环形微波激励腔 The magneto-optical trap for the space cold atom clock The microwave cavity for the space cold atom clock 亮 The laboratory of the space cold atom clock Liu Liang 陈卫标 中国科学院上海光学精密机械研究所 主要科技贡献：确定了空间冷原子钟激光单元、激光稳频以及光学 平台单元的方案，完成了整个系统的可靠性设计和验证。 Xia Wenbing Ji Jingwei Hou Xia Liang Zhaogang 陈卫标 Chen Weibiao Yu Dunhe Sun Yanguang 7 Hu Shanjiang Ye Meifeng 空间冷原子钟照片 天宫二号空间冷原子钟 Photo of the space cold atom clock The space cold atom clock in Tiangong-2 space laboratory 空间冷原子钟抵达发射场测试大厅 研究集体主要完成者 吕德胜 董作人 孙延光 李 唐 赵剑波 胡善江 屈求智 夏文兵 叶美凤 The space cold atom clock arrived at the AIT hall of the launch center 汪 斌 吉经纬 李 侯 琳 霞 宋 丹 梁兆刚 任 伟 俞敦和 8
