A permanent Zeeman slower for Sr atomic clock



A new type of transverse Zeeman slower composed of an array of compactdiscrete neodymium magnets is described. A simple and precisemodel 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 itsmagnetic field can be adjusted in situ. Such a slower would be ideal fortransportable optical atomic clocks and their future applicationsin space physics.
