2024-02-28 High-precision X-ray polarimeter based on channel-cut crystals doi:10.57760/sciencedb.15964 en The raw data submitted covers all the data required in the paper from Fig. 2 to Fig. 5, and is divided into two forms: text document in "dat" format and picture in "tif" format. The specific treatment methods of each set of raw data are as follows:Fig. 2(b) was a direct plot from the raw data fig2(b)_001 and fig2(b)_002, with coordinates corrected for detector gain and motor resolution;Fig. 2(c) was a direct display of the raw data fig2(c)_001 and fig2(c)_002;Fig. 3(b) and Fig. 3(c) were direct displays of the raw data fig3(b) and fig3(c);Fig. 2(b) was a direct plot from the raw data fig4(b), with coordinates corrected for detector gain and motor resolution;Fig. 4(c) was a direct plot from the raw data fig4(b)_001-fig4(c)_007, with coordinates corrected for detector gain and motor resolution;Fig. 5(b) was a direct display of the raw data fig5_001-fig5_021, in which the image position was calibrated according to the detector position, and the image intensity was normalized to the integration time;Each data point in Figure 5(c) is derived from the integration of the intensity of each light spot in Figure 5(b) and normalized by incident light intensity;The inner graph in Fig.5(c) was a direct plot from the raw data fig5in_001 and fig5in_002, with coordinates corrected for detector gain and motor resolution.All data were collected and saved at the BL09B X-ray test beamline of the Shanghai Synchrotron Radiation Facility(SSRF) and the collection date was November 2022.
