Summary of FEL performance as a function of the module length. Top: relative FEL power obtained when using the optical klystron effect (see Fig. 2; the values shown here are averaged between z = 15 m and z = 20 m). Middle: FEL bandwidth obtained with HB-SASE (see Table 2). Bottom: FEL peak power and pulse duration when using a tilt in offset of 1.5 mm (see Table 3). |
