Popis: Most of shielding devices currently used for SERF magnetometers are multilayer cylindrical magnetic shielding barrels. This article studies a new multilayer spindle shaped magnetic shielding barrel for the spin exchange relaxation free (SERF) magnetometer shielding system and uses finite element method (FEM) to compare the analysis results. The results show that the shielding effect of the spindle shaped magnetic shielding barrel is better than the traditional cylindrical magnetic shielding barrel, while the volume is reduced by about 1/5 and the weight is reduced by about 1/4. Therefore, we expect that a small-sized, light-weight, low-cost and more efficient magnetic shielding device can be obtained.
