Figure 11
Amplifier undulator peak power output at 4 keV as a function of z compared with different seed power signals: 10 kW corresponds to the SASE noise case, 5 MW is the single-bunch seed power, and 150 MW is the maximum seed power for the two bunches case. The dashed line corresponds to the coherent power value given by equation (7) for the beam parameters provided in Table 3. |
