The LUX beamline is a novel laser-plasma accelerator, built in close collaboration of the University of Hamburg and DESY, and dedicated for the generation of laser-plasma driven undulator radiation. After the laser-plasma target the electron beams are focused by a quadrupole doublet before entering the undulator to produce soft x-rays at few-nm wavelength.
Due to the high quadrupole gradients of up to 150 T/m, smallest displacements of the quadrupoles lead to dispersive kicks of the bunch. We performed quadrupole scans to determine the offset in the transversal plane between the magnetic quadrupole centers and the beams center of mass to realign the magnets.
