Figure 3
Intensity pattern recorded at 75 eV photon energy with nominally (a) LH, (b) LV and (c) circular polarization. The three images share the same colour bar and have been normalized to the incident beam intensity and to the exposure time. (d) Polar profiles obtained for images (a)–(c) within the region of interest depicted in panel (a). The glitch discontinuities at 30, 150 and 270° are due to the shadow of the mounting frame for the inner conical mirror. (e) Calculated polar profiles for ideal polarization states obtained from equation (2), to be compared with panel (d). |
