Description
Flat corrugated structures designed to generate strong wakefields are used for various purposes in X-ray FEL facilities, in particular for longitudinal and transverse electron beam shaping and for diagnostics. In this contribution we present time-resolved measurements of transverse (dipole and quadrupole) wakefield effects produced in flat corrugated structures by electron bunches with typical parameters in X-ray FELs (few tens of um long and multi-GeV energies). Measurements were done as a function of the distance between the beam and the corrugated plate, beam optics and bunch length. The measurements generally agree with analytical predictions from a wakefield model [K. Bane et al., Phys. Rev. Accel. Beams 19, 084401 (2016)].
