Description
Technical Field
The invention relates to an alkali metal air chamber, in particular to an alkali metal air chamber with high drying efficiency and a drying method thereof.
Background
The alkali metal gas chamber is a special transparent glass bubble for performing ultra-high-sensitivity magnetic field and inertia measurement by utilizing the property of alkali metal atom spinning, and is widely applied to a plurality of research fields such as an atom gyroscope, an atom clock, an atom magnetometer and the like. The inside of the alkali metal gas chamber is provided with an anti-relaxation coating for inhibiting collision relaxation between alkali metal atoms and the inner wall of the gas chamber. The quality of the anti-relaxation coating can affect the quality of the alkali metal gas cell. In the process of manufacturing the relaxation-resistant coating, the inner wall of the air chamber needs to be dried for many times. For example, taking the fabrication of a "dry film" Octadecyltrichlorosilane (OTS) coating as an example, the fabrication process includes four steps: cleaning, coating, filling and curing. In the step of "cleaning", a strong oxidizing Piranha (Piranha) solution is usually used to clean the inner wall of the alkali metal gas chamber to remove impurities attached to the inner wall of the gas chamber, and to form a layer of hydroxyl groups on the inner wall of the gas chamber, thereby facilitating the film formation of the OTS molecules on the surface of the inner wall of the gas chamber. The cleaning step is wet cleaning, and after the cleaning is finished, the inner wall of the air chamber needs to be dried, and then the film coating operation can be carried out. At present, the inner wall of the air chamber is dried by adopting a vacuum oven or a blowing method of inert gases such as nitrogen and the like. When the inner wall of the air chamber is dried by adopting a vacuum oven drying mode, the inner wall of the glass air chamber is polluted and the manufacture of the relaxation-resistant coating and the final quality of the alkali metal air chamber are influenced because the inner wall of the glass air chamber needs to be taken out after being cooled after being dried, namely the drying time is long. When the inner wall of the air chamber is dried by adopting a blowing drying mode of inert gases such as nitrogen and the like, the traditional alkali metal air chamber has the structure that only one tail pipe of the alkali metal air chamber is used for leading the inert gases such as nitrogen and the like to be difficult to enter the air chamber; or two alkali metal gas chamber tail pipes which are directly and oppositely distributed are arranged, inert gases such as nitrogen and the like are difficult to traverse the inner wall of the whole gas chamber, the difficulty of drying the inner wall of the gas chamber by a blowing drying mode of the inert gases such as nitrogen and the like is high, and the inner wall of the whole gas chamber cannot be effectively dried.
