(a) Output of the air-scattering polarization monitors as a function of the angular offset of an X-ray phase retarder crystal. Here, Ix (Iy) represents the X-ray intensities scattered in the vertical (horizontal) direction, corresponding to the intensity of the horizontal (vertical) polarization component. (b) The measured linear polarization rate PL (dots) compared with the calculated results using bandwidths of ΔE/E = 1.1 × 10−4 (solid line) and 0.5 × 10−4 (dotted line). Arrows represent the X-ray polarization states obtained at different offset angles. |
