TI  - Precision control of plasma wakefields for highly efficient and energy-spread-preserving electron acceleration

PY  - 2021
AB  - 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)
