Abstract

The invention provides an atomic dispenser for preparing an atomic gas chamber and a method for preparing an atomic gas chamber, wherein the atomic dispenser of the present invention includes a dispenser main body, gas chamber branches and an alkali metal source, wherein the dispenser The main body of the device adopts a glass disc structure, and the gas chamber branches form a circular symmetrical distribution on the disc surface, while the alkali metal source is located in the center of the other side of the disc, and the distances between all gas chamber branches relative to the alkali metal source are equal. The atomic dispenser with the above structure prepares the alkali metal atomic gas chamber, which is beneficial to improve the consistency of the alkali metal atom packing into the gas chamber, improve the yield of the atomic gas chamber, and improve the performance of the atomic sensing instrument.

Description

technical field [0001] The invention relates to the technical field of atomic gas chamber preparation, in particular to an atomic dispenser for preparing an atomic gas chamber and a method for preparing an atomic gas chamber by using the atomic dispenser. Background technique [0002] The atomic gas chamber is the core physical component of nuclear magnetic resonance gyroscopes, atomic clocks, atomic interference magnetometers and other atomic instruments, and its performance directly determines the accuracy of atomic instruments. In the process of preparing the atomic gas chamber, the packaging process of alkali metal atoms is one of the key technologies, which directly affects the yield of the atomic gas chamber. [0003] Atomic sensing technology uses atoms as the sensing medium, which can realize ultra-precise measurement of physical quantities such as carrier angular velocity, acceleration, time, and magnetic field. In recent years, atomic sensing technology has been h...
