Abstract

The invention discloses a coating alkali metal atom gas chamber curing system for prolonging the atom spin relaxation life. The coating alkali metal atom gas chamber curing system comprises a curing furnace module, a heating module, a refrigeration module and a temperature control module. According to the system, a curing furnace structure of a nested polypropylene inner furnace of a graphite outer furnace is mainly adopted, and direct contact between the polypropylene inner furnace and a high-temperature-resistant heating tape is avoided. The invention further discloses a using method of the coating alkali metal atom gas chamber curing system. According to the system, the coating material (such as paraffin, deuterium polyethylene, olefin and the like) of the inner wall of the alkali metal atom gas chamber can be uniformly distributed, a proper amount of alkali metal atom density of a gas chamber body is guaranteed, so that the alkali metal atom gas chamber is in the optimal working state and can be used for recovering the performance of the damaged alkali metal atom gas chamber under long-time high-temperature work, so that the service life of the atom gas chamber can be prolonged, and meanwhile, the system is suitable for various alkali metal atoms.

Description

technical field [0001] The invention relates to the technical field of atomic gas chamber preparation, in particular to a coating alkali metal atomic gas chamber aging system and a use method for prolonging the atomic spin relaxation lifetime. Background technique [0002] The atomic air cell is the carrier of working atoms and the core device for all experiments and applications involving the interaction between light and atoms. Usually, the atomic gas chamber is generally made of optical glass, and helium or alkali metal atoms (such as potassium, rubidium, and cesium) are encapsulated in a vacuum or other inert gas atmosphere, and other inert gases may be filled as buffer gases and quenching gases. The atomic gas chamber with a longer atomic ground state relaxation lifetime has a wide range of applications, such as atomic magnetometers, atomic clocks, atomic gyroscopes, optical storage, quantum memory, preparation of squeezed states, and detection of new physics.

Problems solved by technology

[0006] However, due to the many preparation steps and complex processes of the atomic gas chamber, it is difficult to ensure the uniformity of the coating material on the inner wall of the atomic gas chamber.

At the same time, since it is difficult to control the density of alkali metal atoms filled into the atomic gas chamber when filling with alkali metal atoms, the atomic gas chamber may cause the magnetic resonance signal amplitude to be too small due to too small working atomic density, or may be too small due to the working atomic density. The large line width of the magnetic resonance signal will be too large, which will affect the working performance of the alkali metal atom gas cell

[0007] At present, there are many manufacturing methods and technologies about the coated alkali metal atomic gas chamber at home and abroad, but there is still a lack of aging methods and systems that can maintain the performance of the coated alkali metal atomic gas chamber. The present invention solves this difficulty
