We have developed a superconducting sextupole magnet with about 50 mm in bore diameter to focus cold neutron beams with large cross‐section and have investigated its focusing and polarizing effect. Large gain in neutron intensity and high neutron polarization have been obtained by numerical simulation for highly collimated neutron beams. We discuss applications of this magnet for small‐angle neutron scattering experiments.
