Figure 3
Available average spectral brilliance from the UE56 and maximum repetition rate of selectable different time-resolved operation modes at different X-ray pulse length. The 500 MHz would correspond to the case that all 400 buckets in the ring would be filled with electrons. In the slicing case (as reduced by R = 10−8), the lower energies are not accessible owing to limits of separating light from sliced electrons at large natural opening angle of the undulator's central radiation cone (photon energy < 250 eV). Peak brilliance in femtoslicing is ∼1022 photons s−1 (0.1% bandwidth)−1 mrad−2 mm−2.
