A hexapole neutron lens approximating the Halbach structure using brick-shaped NdFeB permanent magnets has been realized, achieving two-thirds of the ideal field strength. The neutron optical characteristics of the constructed two hexapole lenses have been numerically simulated and tested in neutron beam experiments, using a 2D position-sensitive detector in time-of-flight regime.
