Figure 2
Left: first-order correlation function (where E is the radiation field) with respect to the bunch center s0 as a function of the longitudinal position s along the bunch and the bunch position Z along the undulator beamline for the radiation at the subharmonic (top) and at the wavelengths of interest (center and bottom). Right: relative bandwidth (top) and FEL power (bottom) along Z for the different cases. |
