| Research Abstract |
We proposed a new method to increase the efficiency of inelastic neutron scattering measurement utilizing the multiple incident energies (Multi-Ei method), and succeeded in the demonstration experiment. To further increase the efficiency of Multi-Ei method, we developed a new Fermi chopper with supermirror-coated slitpackage. We experimentally demonstrated that the transmitted intensity from a new slitpackage becomes stronger in lower energy region, and thus the improvement of efficiency in Multi-Ei method has been achieved.
