      abstract     = {For plasma-wakefield accelerators to fulfill their
                      potential for cost effectiveness, it is essential that their
                      energy-transfer efficiency be maximized. A key aspect of
                      this efficiency is the near-complete transfer of energy, or
                      depletion, from the driver electrons to the plasma wake.
                      Achieving full depletion is limited by the process of
                      re-acceleration, which occurs when the driver electrons
                      decelerate to nonrelativistic energies, slipping backward
                      into the accelerating phase of the wakefield and being
                      subsequently re-accelerated. Such re-acceleration is
                      unambiguously observed here for the first time. At this
                      re-acceleration limit, we measure a beam driver depositing
                      (57 ± $3)\%$ of its energy into a 195-mm-long plasma. This
                      suggests that the energy-transfer efficiency of plasma
                      accelerators could approach that of conventional
                      accelerators.},
