Figure 5
Measured dispersion pattern for grating G1-3 (a) and G2-3 (b) in the range of the zeroth and first diffraction orders at fixed photon energy of 136 eV and constant deviation mount of 162°. No ghost peaks were observed. The positions on the grating are counted from the center (0, 0), X along the grating groove and Y along the incoming photon beam axis. |
