Abstract The atomic vapor cell is a core component in quantum precision measurement instruments, and the atomic relaxation rate is one of the important parameters of the cell.For the measurement of atomic relaxation rate, a microwave cavity was designed by Comsol Multiphysics software, and the microwave propagation process in the atomic gas chamber was simulated, which verified the rationality of the microwave cavity design.A system for measuring the relaxation rate of the atomic vapor cell was built, and the line shape of the Rabi resonance was measured with a fast Fourier transform analyzer(FFT).The cell relaxation rate was obtained by processing the experimental data, and this method is more convenient and accurate than the theoretical calculation of atomic relaxation rates and does not require excessive experimental conditions.
