Schematic Illustration of Pulse Picking by Resonant Excitation

Caption: In regular operation the non-excited bunches (grey) emit undulator radiation on-axis. A detour in the electron beam (bump) makes that this regular radiation is emitted off-axis and dumped into an aperture. Only the part of the radiation from a quasi-resonantly excited bunch (blue) can enter the beamline mimicking a turn-by-turn single bunch emission.
