A permanent magnet Zeeman reducer
By using cylindrical permanent magnets of different thicknesses and non-magnetic discs in the Zeeman reducer, the problems of existing devices being unable to reserve light-passing holes and having complex assembly and disassembly have been solved. This has enabled effective deceleration and collimation of atomic beams, simplified magnetic field adjustment, and promoted the miniaturization of the device.

Abstract
This application discloses a permanent magnet Zeeman reducer, comprising: a vacuum circular pipe, two sets of U-shaped fastener assemblies, and four non-magnetic circular tubes; wherein the vacuum circular pipe and the four non-magnetic circular tubes are fixed between the two sets of U-shaped fastener assemblies, with the vacuum circular pipe as the central axis, and the four non-magnetic circular tubes are arranged symmetrically around the vacuum circular pipe; the vacuum circular pipe allows atomic beams to pass through; each non-magnetic circular tube contains several cylindrical permanent magnets of different thicknesses and several non-magnetic discs of different thicknesses, arranged in a regular pattern according to the required magnetic field strength. The reducer of this application has a long effective deceleration area, is easy to assemble and disassemble, and quickly establishes the magnetic field strength distribution.
