Figure 7
Light polarization dependence of the beam profiles (seen from the upstream side). The photon energy and the exit slit were set to 100 eV (300 lines mm−1 VLSG) and 30 µm, respectively. The measurements were performed in the order of the horizontal-linear polarization, right-circular polarization, vertical-linear polarization, and left-circular polarization. Integrated intensities along the vertical and horizontal axes are shown at the bottom. The origin of the vertical and horizontal axes corresponds to the maximum intensity in the integrated intensity curves of the beam with horizontal linear polarization. |
