Problems solved by technology

[0005] There are two problems in the production process of the above-mentioned atomic gas chamber: 1) the filling process of the alkali metal is to use a thermal spray gun to "drive" the solid alkali metal deposited on the inner wall surface of the alkali metal sub-packaging container into the atomic gas chamber by sequential distillation, because It is not a uniform filling method, so it is difficult to guarantee the filling amount and the uniformity of filling, and this method will cause a large amount of alkali metal to be deposited in the alkali metal collection container, resulting in waste of alkali metal; 2) The way of filling alkali metal in sequence is not conducive to Mass production of atomic gas chambers

Abstract

The invention discloses an atom air chamber preparation device with quantitative filling of alkali metal. The preparation device comprises a gas filling and exhausting system, N atom air chambers, analkali metal split charging vessel, a temperature tank, a TEC temperature control system, an alkali metal generator, a vacuum valve 1 used for being connected with the gas filling and exhausting system and the alkali metal split charging vessel, a vacuum valve 2 used for being connected with the alkali metal split charging vessel and the alkali metal generator and a vacuum valve 3 used for being connected with the alkali metal split charging vessel and a first atom air chamber. For the atom air chamber preparation device and method provided by the invention, by actively and accurately controlling temperature distribution in the alkali metal split charging vessel, orientated deposition of the alkali metal is realized; by utilizing calibration of the deposition rate of some an atom air chamber, quantitative filling of the alkali metal is realized; and compared with the traditional filling mode, quantitative control of the filled alkali metal is realized, the filling consistency is improved at the same time, and a feasible solution is more provided to batch production of the atom air chambers.

Description

technical field [0001] The invention relates to a preparation device and method for an alkali metal atomic gas chamber, in particular to a quantitative filling device and method for an alkali metal in an atomic gas chamber used for nuclear magnetic resonance gyroscopes, atomic gyroscopes and other quantum instruments, and belongs to the component preparation technology field. Background technique [0002] The atomic gas chamber is the core device of quantum instruments such as atomic gyroscopes, atomic magnetometers, and atomic clocks. Parameters such as the density of alkali metal atoms in the atomic gas chamber, the species of inert gas atoms, the spin relaxation time of the nucleus, and the shape and volume of the atomic gas chamber directly affect the performance of quantum instruments, and are one of the common technologies of quantum instruments. At present, the preparation of high-performance atomic gas chambers is one of the key issues that seriously restrict the br...
