Figure 3
Schematic view of a transverse-deflecting cavity (TDS) followed by an energy spectrometer. The electron bunch travels from left to right. It experiences an arrival-time-dependent deflection in the cavity in the y-plane. Passing through a subsequent dipole the electrons are dispersively kicked in the x-plane. This leads to an image that shows the longitudinal profile in one direction and the energy spectrum in the other. A characteristic measurement of the longitudinal phase space distribution is shown at the bottom. |
