Magnetic Shielding Simulation for a Low Noise Atomic Comagnetometer

Design and simulation studies of a low-noise magnetic shielding unit were carried out for atomic comagnetometer applications. The aim of this study is to find the optimum solution with the highest attenuation rate by characterizing the performances of magnetic shielding units with different designs. Simulations of four different designs were carried out. As a result, it has been determined that with a four-layer magnetic shielding, attenuation rates greater than 106 can be obtained and the magnetic field of 50μT can be reduced below 1pT.
