VIII-5 Study of Dynamics on High Resolution Chopper Spectrometer

The High Resolution Chopper Spectrometer (HRC) is an inelastic neutron scattering instrument to study dynamics of materials in a wide energy space with high resolutions. Improvement of the HRC for realizing neutron Brillouin scattering experiments has enabled dynamical studies of polycrystalline and liquid samples. In high resolution experiments in a conventional energy momentum space, dynamics in numbers of strongly correlated electron systems have been revealed. In sub-eV neutron spectroscopy, studies of high energy magnetic excitations are in progress, and possibilities of observing electric excitations are discussed.
