A schematic illustration of the measurement system on the beamline at J-PARC (BL10). Pulsed neutrons traveled from the source moderator through the beamline toward the detector through an YbSn3 sample. The collimator was installed 8 m downstream from the moderator. The detector and sample were cooled down to 7.9 K by using a Gifford–McMahon refrigerator. |
