説明

A 2D-detector and an analyzer had been installed on iNSE neutron spin echo spectrometer for wide-area data acquisition. Since the areas of the 2nd π/2 spin flipper and the last Fresnel coil were not wide enough for a full area measurement, only the center area of the detector had been used. In 2006, we renewed the spin flipper and the Fresnel coils to expand the detection area. To improve the efficiency of the data acquisition, we proposed a novel method for phase correction of NSE signals. Finally, the efficiency of the NSE measurement increased by approximately one order of magnitude.
