High Resolution Chopper Spectrometer (HRC) at J-PARC

To study condensed-matter dynamics over a wide energy–momentum space with high resolution, we constructed the High Resolution Chopper Spectrometer (HRC) at beamline BL12 at the Materials and Life Science Experimental Facility (MLF) of the Japan Proton Accelerator Research Complex (J-PARC). With the construction nearly completed, we proceeded to characterize the HRC. We confirmed that, under limited conditions, the neutron intensity and energy resolution of the HRC agree well with the design values.
