Figure 6
(a) Spectral distribution of a single-pulse SASE beam (9 keV) for different pulse durations achieved by a variation in the compression of the electron bunch. The black curves are slightly shifted from the central energy for better visibility. (b) Average of the g2 correlation function for the two different pulse characteristics shown in (a). A total of 17 360 spectra are used, and the fits are obtained by fitting a Gaussian peak function. |
