Abstract：A magnetic field of the Zeeman slower is designed for 87Sr atom based on Zeeman effect and Doppler cooling theory with the experimental condition. A spindle-shaped coil is manufactured according to the　  simulated values of the layers, the turns, the current and other parameters. The measured result shows that the longitudinal magnetic field of the manufactured spindle-shaped coil satisfies the requirement of 87Sr optical lattice clock experiment.

Key words：Zeeman effect；Doppler shift；optical clock；Zeeman slower
