Optimal modeling on magnetic shielding cylinder of atomic spin gyroscope considering transverse shielding factor

The atomic spin gyroscope needs work at the weak magnetic field environment, thus, it presents strict request to the performance of the magnetic shielding. In this paper, based on the transverse shielding factor, the parameter optimization model was established, and the influences of various parameters on the transverse shielding factor were simulated via software Matlab. After building the simulation models, the shielding efficiencies of 114 dB and 96 dB of the optimization magnetic shielding and the non-optimization one were obtained, respectively. The experiment results indicated that the shielding efficiency of the optimization magnetic shielding cylinder was about 3 times higher than that of the non-optimization one.
