(a) Normalized XAFS spectra of the Cu K-edge measured at different step modes of the Bragg motor (1/20-step mode, 1/4-step mode, 1/2-step mode and full-step mode). (b) Magnified plot showing the noise level at different step modes of the Bragg motor (1/20-step mode, 1/4-step mode, 1/2-step mode and full-step mode). |
