Atomic gas chamber glass bulb pressure resistance test device and test method

Abstract

The invention discloses an atomic gas chamber glass bulb pressure resistance test device and test method. The test device comprises a high-pressure gas cylinder, a ball valve I, a pressure bearing cylinder, a pressure sensor, a safety valve, a ball valve II, a ball valve III, a stainless steel connector, an anti-explosion cylinder, a gas chamber glass bulb, a gas conveying pipeline and a gas exhaust pipeline. An outlet of the high-pressure gas cylinder is connected with one end of the gas conveying pipeline, and the other end penetrates through the anti-explosion cylinder and then is connected with the gas chamber glass bulb. The ball valve I, the pressure bearing cylinder, the ball valve III and the stainless steel connector are sequentially arranged on the gas conveying pipeline in the direction from the high-pressure gas cylinder to the gas chamber glass bulb. The pressure sensor and the safety valve are arranged on the pressure bearing cylinder. The gas exhaust pipeline is communicated with the gas conveying pipeline and is positioned between the pressure sensor and the ball valve III. The ball valve II is arranged on the gas exhaust pipeline. According to the invention, accurate quantification of the pressure endurance capability of the gas chamber glass bulb is realized, the test efficiency and speed are improved, and the safety of testers and equipment is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of atomic gas chamber manufacturing, and in particular relates to a pressure-resistant testing device and a testing method for a glass envelope of an atomic gas chamber. Background technique [0002] The high-pressure atomic gas chamber is the core component of the SERF gyroscope and SERF magnetometer. The performance of the atomic gas chamber will directly affect the final accuracy of the above instruments. In order to prepare a more stable SERF state, the filling pressure of the atomic gas chamber needs to reach several to more than a dozen atmospheres to suppress the spin-exchange collision relaxation of polarized atoms to achieve extremely high-sensitivity quantum precision measurement. [0003] In order to reduce the adverse effect of stray light on the signal, the high-pressure atomic gas chamber mostly adopts a glass cubic / cylindrical structure. The usual operating procedure is to first evacuate the ...

Problems solved by technology

The difficulty in testing the pressure resistance performance of glass bulbs lies in: the tiny glass bulbs with a size of less than 10mm are more sensitive to vibration during the test; cause safety hazard
