Figure 4
Experimental set-up for polarization measurement at the SACLA BL3 beamline. Here, PD1–PD6 represent silicon PIN photodiodes. PD1 was used to monitor the X-ray intensity diffracted from the diamond phase retarder crystal. PD2, PD3, PD4 and PD5 were used to determine the degree of linear polarization by monitoring the intensities of the Thomson scattering by air in the vertical and horizontal directions. PD6 measured the transmitted intensity through the ferromagnetic sample.
