Neutrons are a powerful research tool and provide scientists unprecedented insight into the structure and properties of materials. Experiments with spin-polarized neutrons demand sophisticated neutron optical devices embedded in tailored static magnetic fields. For this study we performed a depolarization analysis of a magnetic guide field interface of a neutron beam-line. By using the AC/DC module of COMSOL Multiphysics® the magnetic flux density and the corresponding neutron depolarization coefficient were calculated for a variety of guide field configurations. Based on this FE-analysis the magnetic-design of the neutron beam-line under investigation was successfully optimized.
