摘　　要：应用塞曼效应和多普勒冷却的理论,结合实验条件计算了87Sr原子束塞曼减速器的磁场。数值模拟给出了磁场线圈的层数、圈数、供电电流和其他参数,并据此制作了纺锤状线圈。测量结果表明,研制的纺锤状线圈的轴向磁场满足87Sr光晶格钟实验的要求。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.
