A new type of transverse Zeeman slower composed of an array of compact discrete neodymium magnets is described. A simple and precise model of such a slower based on magnetic dipoles is developed. The design of such a slower for Sr atoms is presented. The slower needs no high currents or water cooling and the spatial distribution of its magnetic field can be adjusted in situ. Such a slower would be ideal for transportable optical atomic clocks and their future applications in space physics.
