By means of interaction between neutron magnetic moment and magnetic sextupole that leads to a specific path equation for neutrons, the neutron motion in a sextupole magnetic field has been obtained. By utilizing the result, theconditions for focusing the cold neutron beam on the end of the magnet have been investigated. Also, using the simulated results, the focused wavelength has been obtained for different conditions depending on the dimensions of the sextupole magnet and its strength. The effect of the dimensions of the neutron source is also investigated on the focusing process.
