Embodiment Construction

[0031] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0032] The invention provides a high-reliability and high-performance sapphire-loaded microwave cavity, which solves the problems of complex realization process and poor performance and reliability of the traditional scheme. The overall dimension of the cavity is the same as that of the traditional solution, and the internal filling volume is greatly increased. This not only ensures the miniaturization of the atomic clock, but also improves the performance of the whole machine and the environmental adaptability of the whol...

Abstract

The invention discloses a sapphire loading microwave cavity for a miniature hydrogen atomic clock; the sapphire loading microwave cavity comprises a microwave cavity barrel, sapphire filling medium and a hydrogen atom storage bulb, wherein the sapphire filling medium is arranged in the microwave cavity barrel and includes a first medium ring, a second medium ring and a third medium ring stack-connected in wedge form, and the hydrogen atom storage bulb is arranged in a space formed by the first medium ring, the second medium ring and the third medium ring. Loading and storage are separated for the sapphire microwave cavity with reliability, index performance improvement and cost control considered; the three wedged sapphire stacked medium rings are used as a loading material for the microwave cavity, and the sapphire loading microwave cavity with high reliability and performance is provided. At the premise that the dimensional size of the whole cavity is equal to that of the traditional schemes, inner filling size is increased greatly, miniaturization of the atomic clock is guaranteed, and machine performance and machine environmental adaptability are also improved.

Description

technical field [0001] The invention relates to the technical field of atomic clocks. More specifically, it relates to a sapphire-loaded microwave cavity for small hydrogen atomic clocks. Background technique [0002] An atomic clock is a precision time measurement instrument that uses electromagnetic waves emitted when atoms absorb or release energy to keep time. It is widely used in positioning, navigation, communication, military and other fields. Because this electromagnetic wave is very stable and controlled by a series of sophisticated instruments, atomic clocks can be very accurate. At present, the elements used in atomic clocks include hydrogen (Hydrogen), cesium (Cesium), rubidium (rubidium), etc. The accuracy of atomic clocks can reach an error of 1 second every 20 million years, which provides a powerful foundation for astronomy, navigation, and space navigation. Assure. [0003] With the development of space geodetic technologies such as satellite laser rangin...
