Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of weak magnetic equipment, in particular to a test tool of an atomic magnetometer. BACKGROUND

[0002] The SERF atomic magnetometer, i.e. the Spin-exchange relaxation-Free (SERF) atomic magnetometer, is an alkali atomic magnetometer with ultra-high measurement sensitivity (sub-fT ~ fT level). The working principle of the SERF atomic magnetometer is based on the magnetic resonance effect of alkali atoms (such as rubidium or cesium) in the spin-exchange relaxation-free state. By heating to increase the density of alkali atoms, the spin exchange rate is much larger than the Larmor precession frequency. In this state, the spin polarization rate of alkali atoms is very high, and the change of external magnetic field is very sensitive. When the external magnetic field acts, the spin direction of the alkali atoms will change, resulting in a change in the rotation angle of the linearly polarized light passing through the gas chamber. By detecting the change of the rotation angle, the size and direction of the magnetic field can be calculated. The SERF atomic magnetometer needs to be tested for sensitivity, accuracy, stability and dynamic range, etc. The test tool in the traditional technology cannot detect the SERF atomic magnetometer in large quantities, which affects the detection efficiency.
