| 520 | _ | _ | |a Plasma-wakefield accelerators driven by intense particle beams promise to significantly reduce the size of future high-energy facilities. These applications require an energy-efficient acceleration process with a well-controlled energy spectrum, both of which can be achieved simultaneously by tailoring the plasma wakefield. Prerequisite for such control of the wakefield is its precise measurement. Here we discuss a new measurement technique that enables femtosecond-level sampling of the longitudinal electric fields and that is particularly powerful due to its operational simplicity. Using this method, we experimentally demonstrated optimal beamloading in a nonlinear electron-driven plasma accelerator by wakefield flattening at the few-percent level. Bunches were accelerated at a gradient of 1.3 GV/m and with an energy-transfer efficiency of (42±4)% while preserving per-mille energy spreads with full charge coupling. These results open the door to high-quality operation of future plasma accelerators through precise control of the acceleration process. |
