Description

We have developed a magnetic neutron lens (MNL) based on an extended Halbach-type permanent sextupole magnet. The effective aperture size is 30 mm in diameter and the length is 2400 mm. The sextupole magnetic field distribution | B |=(G/2) r 2 with the gradient coefficient G=10,660±530 T/m2 are generated inside the magnet, where r is the distance from the magnet center axis. The neutron-focusing property is investigated by using pulsed polarized neutrons. The obtained results are discussed in comparison with numerical simulation results. The application to the focusing-geometry small-angle neutron scattering experiments is discussed
