BL12 HRC High Resolution Chopper Spectrometer

Summary

HRC enables us to access the wide momentum (Q) and energy (E) for conducting forefront researches on dynamical properties in material with the best resolution ever!

Research ObjectivesDynamics on atoms, molecules and spins in condensed matter.
FeaturesNewly developed Fermi chopper can provide fine tuned neutrons. A large array of detectors (target -30°~130°) makes it possible to study wide range of motions.
