A demonstration study of focusing geometry SANS using a magnetic lens

A demonstration study of focusing geometry small-angle neutron scattering (FSANS) experiment was successfully performed using a superconducting sextupole magnet as a neutron focusing device and a polarized cold neutron beam. The obtained small-angle neutron scattering intensities from monodispersed SiO2 spherical particles were discussed in terms of the scattering function taking into account the q-resolution.
