| contents | A conceptual design study of a Transverse Deflecting Structure (TDS) for longitudinal beam diagnostics at the DALI accelerator facility is presented. The TDS provides a time-dependent transverse kick to the electron bunch, enabling direct measurement of the longitudinal bunch profile and reconstruction of the longitudinal phase space when combined with a dispersive spectrometer section. The report reviews the physical principles of RF deflecting cavities, including the transverse kick mechanism, temporal-to-spatial mapping, and the relationship between beam optics and achievable temporal resolution. Engineering considerations such as RF frequency choice, cavity design, wakefield effects, timing synchronization, and mechanical stability are also discussed. |
