Cold neutron beams can be focused by a strong sextupole magnetic field. A permanent magnet sextupole lens whose focusing strength can be synchronously modulated at the rate of pulsed cold neutron beams is under development. This device should keep the focal point for pulsed neutron beams whose wavelength spreads as a function of time of flight. This kind of device improves the utilization of valuable neutrons and saves experiment time and costs. It will raise linac based small neutron sources as a good counter part to large powerful neutron facilities. Experimental results that were obtained at Institute Laue-Langevin (ILL) are also described.
