Outline of Final Research Achievements

Improvement of a neutron spin phase contrast imaging technique using multi-layered neutron spin splitters could not be performed because the JRR3 could not be operated. However the multi-layered spin splitters and controlling system of them were prepared by the support of the aid. The demonstration can be performed so promptly after starting the JRR3 operation.
On the other hand, a visualization test of magnetic steel sheet was performed at J-PARC. Change of magnetic domains with different applied magnetic fields were successfully visualized.
