The High Resolution Chopper Spectrometer (HRC) provides opportunities for dynamical studies of materials in a wide energy-momentum space with high resolution in the world standards. In particular, the option of neutron Brillouin scattering (NBS) makes the HRC different from other chopper spectrometers. Coherent excitations in non-single-crystal samples can be observed with NBS. On the HRC, NBS experiments were made feasible and some results were obtained.
