Comparison of the longitudinal wake potential at the exit of the DLW from analytical results (blue solid line) and dynamic simulation results from ECHO2D (red squares) for a monopole (a), dipole (b), quadrupole (c) and hexapole (d) field under the same conditions. The longitudinal coordinate s is defined with respect to the bunch tail. The calculated wake potential sums the first 15 resonant frequencies for each mode. The transient effect at the entrance and exit can be reasonably excluded. |
