| Abstract: | This paper designs a non magnetic heating coil for millimeter class atomic vapor cells to meet the heating and magnetic suppression requirements of atomic vapor cells of a miniature nuclear magnetic resonance gyroscope (mini NMRG). Thermal magnetic simulations are used to investigate the effect of heating coil structure parameters and heating current on cell temperature and magnetic fields of atomic vapor cells. The parameter optimization of the heating coil structure and current is completed for a given cell heating configuration. The simulation results from the optimization show that the maximum DC residual magnetic field intensity inside the cell is <0.3 nT, and the designed heating coil and configuration can meet the non magnetic heating requirements of the prototype vapor cell. |
