We report on design and construction of a Zeeman slower for strontium atoms, which will be used in an optical atomic clock experiment. The paper describes briefly required specifications of the device, possible solutions, and concentrates on the chosen design. The magnetic field produced by the built Zeeman slower has been measured and compared with the simulations. The system consisting of an oven and Zeeman slower is designed to produce an atomic beam of 10–12 s–1 flux and final velocity of ~30 m/s.
