Laser-plasma accelerators are promising candidates to drive compact, laboratory-scale free-electron lasers. However, the unique properties of plasma accelerated electron beams present a challenge to the conventional beam transport and lasing concepts. Here, we present the upgrade of the LUX beamline, that is built and operated by the University of Hamburg and DESY, with the goal of demonstrating FEL gain from a laser-plasma accelerator. The beamline design features a chicane to decompress the electron beam and relax the conditions on the initial beam parameters from the plasma target. The presented concept shows a balancing between the decrease in beam current due to the decompression, the effects of coherent synchrotron radiation in the chicane, and the manipulation of the phase-space to optimize the slice properties of the beam.
