      abstract     = {Energy-efficient plasma-wakefield acceleration of particle
                      bunches with low energy spread is a promising path to
                      realizing compact free-electron lasers and particle
                      colliders. High efficiency and low energy spread can be
                      achieved simultaneously by strong beam loading of plasma
                      wakefields when accelerating bunches with carefully tailored
                      current profiles [M. Tzoufras {et al.}, Phys.Rev.Lett.~101,
                      145002 (2008)]. We experimentally demonstrate such optimal
                      beam loading in a nonlinear electron-driven plasma
                      accelerator. Bunches with initial energy of 1 GeV were
                      accelerated by 45 MeV with an energy-transfer efficiency of
                      $(42±4)\%$ at a gradient of 1.3 GV/m while preserving
                      per-mille energy spreads with full charge coupling,
                      demonstrating wakefield flattening at the few-percent
                      level.},
