Abstract

The invention relates to an integrating sphere cooling and microwave integrating cavity used for miniaturized cold atomic frequency standard, which is formed by connecting an integrating sphere, a cylindrical microwave cavity, a flange and a four-way connector through supporting screws. The integrating sphere cooling and microwave integrating cavity has the characteristics of having the advantages of mature technologies, easiness in processing and large uniform central microwave field region for the cylindrical microwave cavity and having the advantage of cooling for the integrating sphere.

Description

technical field [0001] The invention relates to laser cooling, atomic frequency standard and microwave technology, in particular to an integrating sphere cooling and microwave integrated cavity used for integrating laser cooling and microwave field in transportable miniaturized cold atomic frequency standard. Background technique [0002] The emergence of atomic frequency standards has brought revolutionary changes to the measurement of time standards and has been widely used, such as GPS (Global Satellite Navigation and Positioning System). With the development of society, people put forward higher requirements for time measurement. Cold atomic frequency markers have very high time measurement accuracy and stability, which can meet social requirements. But generally cold atomic clocks are bulky and much heavier than hot atomic clocks. Therefore, we urgently need to develop a stable, reliable, transportable, high-precision miniaturized cold atomic clock. Currently, ESA is ...
