Figure 10
(a) Image of the beam spectrum projected by the C333 spectrometer crystal. The image is an average of 15 frames. The parts of the spectrum removed by the C111 and C220 splitters are clearly visible as empty bands. The shape of the beam and non-uniformities are also visible. The part of the image considered for calculating the section in graphic (b) is visualized as a black rectangle. (b) Section of the spectrometer image over the X direction, taken on the center of the image and averaged over 40 pixels in the Y direction (260 µm on the detector, as pixel size is 6.5 µm). |
