A high stability magnetic field applied in atomic magnetometer system

摘要：

A pair of Helmholtz coils producing a magnetic field with super-high stability in atomic magnetometer experiment has been designed and realized. To drive this coils, we developed a DC constant current source, which can provide a near 1 raA DC current with short-term stability of 5.8 parts in 107 in experimentally. Analysis shows that the stability of center magnetic field is about 0.06 pT.
