A Study on dynamics of non-crystalline materials and superionic conductors by chopper spectrometers in J-PARC

Nakamura, Mitsutaka   

Studying the dynamical properties of structurally isotropic materials such as glass, liquid, and polycrystalline powder samples, the inelastic neutron scattering measurement by chopper spectrometer in pulsed neutron source shows the whelming strength compared with that by triple axis spectrometer in research reactor. When a new material exhibiting the unusual physical properties is discovered, it might be difficult to grow the single crystal and only possible to obtain the powder form in the early stage of research. The strong neutron beam of J-PARC can provide opportunity promptly for the dynamical study of newly-discovered materials. The chopper spectrometers in J-PARC have the potential to create innovative research outcomes.
