To study the relationship of atomic beam flow with cooling intensity, laser detuning, and magnetic field gradient, the numerical simulation is performed and a two-dimensional magneto-optical trap setup is built. A low-velocity atomic beam flow is generated with a total flux of 2.1 109/s. Theoretical analysis and experimental results are in good consistence. Optimal detuning and magnetic field gradient can produce the largest atomic beam flow.
