Figure 2

Simulated phase-space of the 3 GeV electron beam of SwissFEL at two locations: after the DLA interaction (first row, (a–d)) and after the propagation through the switchyard to the Athos beamline and optimal compression (second row, (e–h)) A strong increase in slice energy spread is observed, compare sub-figure (b and f), whereas the slice emittance remains unchanged (sub-figure (c and g)). The noise in (g) appears larger than in (c), as the bin width is reduced to resolve the short spikes. After optimal compression peak currents of up to 5 kA are predicted by this simulation (h).
