(a) The longitudinal phase space (blue, orange, yellow, purple, green) at the exit of the dispersion section with different modulator lengths (0.6 m, 1.2 m, 1.8 m, 2.4 m, 3 m) and the same bend angle (30 mrad). (b) The longitudinal phase space (blue, orange, yellow, purple, green) at the exit of the dispersion section with different strengths (10 mrad, 30 mrad, 50 mrad, 70 mrad, 90 mrad) of the first dipole and the same modulator length (1 m). (c) The peak bunching factor distribution of the 15th harmonic with different strength of the dipole and different modulator length. |
