Figure 5
An echo signal in a 4 × 4 cm pixel cell in the central part of the SNS-NSE detector. The echo-shape function shown corresponds to the spectral intensity in the range λ = 5–8 Å obtained from the average time-of-flight spectrum measured at the detector. The phase symmetry current Iphase pertains to a symmetry coil of 80 turns around the beam. The echo results shown come from a reference sample measurement at J = 0.04 T m and 2θ = 8.6°. The solid symbols correspond to the phase scan around the symmetry point (red dotted line). The open symbols represent the up and down intensities. The extracted values for amplitude a and average b are indicated. |
