Abstract: Beam-driven plasma-wakefield acceleration has the potential to reducethe size and construction cost of large-scale accelerator facilities, byproviding accelerating fields orders of magnitude greater than that ofconventional accelerating structures. Affordable running costs requiredemonstration of high energy-transfer efficiency from the wall-plug tothe accelerated bunch. For this, drive bunches must be efficientlyproduced, strong decelerating fields must be sustained for the drivebunches until their energy is depleted, and the resulting acceleratingfields must be strongly beam loaded by the trailing bunches. Here weaddress the second of these points, showing measurements using a 500MeV drive bunch where (50±7)% of its total energy is deposited intoa 20 cm long plasma. This level of energy-transfer efficiency demon-strates that plasma accelerators hold the potential to become compet-itive with conventional accelerators.
