We present experimental results on a plasma wakefield accelerator (PWFA)driven by high-current electron beams from a laser wakefield accelerator(LWFA). In this staged setup stable and high quality (low divergence and lowenergy spread) electron beams are generated at an optically-generatedhydrodynamic shock in the PWFA. The energy stability of the beams produced bythat arrangement in the PWFA stage is comparable to both single-stage laseraccelerators and plasma wakefield accelerators driven by conventionalaccelerators. Simulations support that the intrinsic insensitivity of PWFAs todriver energy fluctuations can be exploited to overcome stability limitationsof state-of-the-art laser wakefield accelerators when adding a PWFA stage.Furthermore, we demonstrate the generation of electron bunches with energyspread and divergence superior to single-stage LW-FAs, resulting in buncheswith dense phase space and an angular-spectral charge density beyond theinitial drive beam parameters. These results unambiguously show that stagedLWFA-PWFA can help to tailor the electron-beam quality for certain applicationsand to reduce the influence of fluctuating laser drivers on the electron-beamstability. This encourages further development of this new class of stagedwakefield acceleration as a viable scheme towards compact, high-qualityelectron beam sources.
