Direct-geometry polarized inelastic spectrometer is designed to carry out neutron inelastic and quasi-elastic scattering experiments. This spectrometer mainly studies the dynamics of materials, especially the elementary excitation in condensed matter physics and the relaxation behavior in soft matter physics.

The research fields of the spectrometer include the mechanism of high-temperature superconductors, quantum liquids, phonons in ferroelectric materials, vibration spectra in polymers and biological macromolecules, etc.
