Abstract

A frequency chain for converting the frequency of an optical clock based on ultracold 87Sr atoms is updated for its comparison with the frequency of microwave standards from the State Primary Standard of time and frequency units and the national time scale, GET 1-2018. The results of the corresponding experiments are reported and analysed. An instrumental complex for reproducing and keeping the time and frequency units and the national time scale of the primary standard is described; this complex includes an optical clock based on strontium atoms and microwave standards of new generation. The order of the atomic time scale generation with application of optical clocks is also determined.

朝向VNIIFTRI的光学时标
更新了基于超冷87Sr原子的光时钟频率转换的频率链,并将其与国家时间和频率单位主要标准GET 1-2018的微波标准频率进行了比较。对相应的实验结果进行了报道和分析。描述了一种用于再现和保存原始标准的时频单位和国家时标的仪器复合体;这个综合体包括一个基于锶原子和新一代微波标准的光学时钟。并确定了应用光钟产生原子时标的顺序。
