Figure 10
Measured projection (a) and reconstructed emissivity (b) as a function of the lateral position (Y) and radial position (R), respectively, for scans in the horizontal and vertical direction. Gas pressure: 400 mbar argon; undulator gap: 10 mm; beam size: 2 mm × 2 mm. The signal of the four different channels has been normalized to the same maximum value and averaged. The gray area represents the area illuminated by the X-ray beam. Note that in this region both horizontal and vertical profiles match. |
