Figure 7
Raw data recorded during a continuous XES scan performed on the Cu Kα emission lines. (a) The recorded SBCA pitch positions as a function of time. The positions are shown as deviations from the position at which the spectrometer was configured prior to the continuous scan (Bragg angle of 79.81° corresponding to 8035 eV). The SBCA pitch was configured to move with a slower speed in the regions corresponding to the Kα1 and Kα2 peaks and faster otherwise. The inset shows the recorded pitch positions during the first few seconds and shows the 150–200 ms delay between the individual SBCA pitch positions arising due to the asynchronous motion. Black circles display the representative times selected for the Pilatus 100K images shown in panel (b). Labels (i), (ii) and (iii) correspond to the peak of the Kα1 line, a point in between the Kα1 and Kα2 lines, and the peak of the Kα2 line, respectively. (b) Recorded Pilatus 100K images demonstrating the changes in the position and the intensity of the SBCA reflections during the SBCA pitch motion. |
