L C L S C O N C E P T U A L D E S I G N R E P O R T Figure 7.45 Normalized rms projected emittance along the <strong>LCLS</strong> accelerator, including CSR in every bend magnet, and for perfectly aligned components (black: γε x, blue: γε y). The slice emittances, both before and after the accelerator for the case with CSR, is shown in Figure 7.46, where “Slice Number” refers to the bunch length coordinate (bunch head at slice-1). The dashed/red lines (x at left, y at right) represent slice emittance at 150 MeV (at L0-linac exit). The solid/blue lines (x at left, y at right) represent slice emittances at 14.35 GeV (at undulator entrance). The large emittance peaks at bunch head and tail at 150 MeV contain very little charge and are washed into the core of the beam after compression and acceleration where they contribute only weakly to the emittance of the core. Figure 7.46 Slice emittances (x at left, y at right) at 150 MeV (dash/red) and 14.35 GeV (solid/blue) after entire <strong>LCLS</strong> accelerator, including CSR. Bunch head is at slice number-1. 7-72 ♦ A C C E L E R A T O R
L C L S C O N C E P T U A L D E S I G N R E P O R T The effects of CSR also change the final projected energy spread, but have very little effect on the bunch length. Figure 7.47 (left) shows the longitudinal phase space at 14.35 GeV at entrance to undulator with CSR effects included in all bends. The rms projected energy spread is 0.1%, including the large tails, but the energy spread of the core slices is 0.1%) have been cut out here (80% of the particles remain) in order to better reveal the slice energy spread, rather than the extreme tail effects.
