Physical review accelerators and beams 20(4), 042801(2017). doi:10.1103/PhysRevAccelBeams.20.042801, Generation of a well-aligned bunch train is of vital importance for preserving the beam quality in a Plasma Wake Field Accelerator (PWFA). 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),while the RFD strength and the RFD phase for each bunch do not need to be known., Published by American Physical Society, College Park, MD
