Abstract
An optimized design of a permanent Zeeman slower for an ytterbium optical lattice clock is presented. The dependences of the magnetic field distributions on the detuning and intensity of the cooling laser are studied. The length and corresponding magnetic field distribution of the slower are analyzed by varying the efficiency parameter and saturation parameter of the cooling laser. Considering the slowing efficiency and the loading rate of the magneto-optical trap, the optimum length of the slower is about 15 cm, and its width is about 10 cm in our case. Finally, an adjustable slower with a slowing efficiency of 15.5% is proposed.
