Misalignment measurement of femtosecond electron bunches with THz repetition rate
Generation of a well-aligned bunch train is of vital importance for preserving the beam quality in a
plasma wake-field accelerator. The simultaneous measurements of the relative misalignments in both
planes, of the individual femtosecond electron bunches with THz repetition rate in a train, are reported and
analyzed with simulations. The new method proposed in this paper demonstrates that the measurements can
be done quickly by applying a single quadrupole scan together with a radio-frequency deflector (RFD),
