Figure 6
A selected region of a SASE pulse spectrum, the same as in Fig. 3(b), and the spectra of the diffracted waves for the C*(220) reflection from D = 20 µm crystal and the distance from the bent-crystal spectrometer to a detector L = 0.6 m. (a) Convex bending, R = +0.1 m, (b) concave bending, R = −0.1 m. |
