Figure 1
Experimental set-up with a phase plate. X-ray propagation directions are indicated by blue arrows, polarizations by red ones. Synchrotron light arrives from the left, horizontally polarized (π). ζ = 2χ is the rotation angle of the incident polarization. η is the rotation angle of the polarization analyzer crystal; the zero positions of the two angles, corresponding to σ and σ′ polarizations, respectively, are represented by dashed lines. The solid line is the rocking axis of the polarization analysis crystal θPA. (Reproduced from Mazzoli et al., 2007.) |
