Beam-driven electron acceleration in plasmas — •Richard D'Arcy — DESY, Notkestr. 85, 22607 Hamburg, Germany

Electric fields in plasma waves, driven by relativistic particle beams, can accelerate particles to tens of GeV energies over metre-scale distances. These accelerating gradients, orders of magnitude higher than those achievable in conventional radio-frequency cavities, have the potential to drastically reduce the footprint of future photon-science and high-energy-physics facilities if a number of technical challenges can be met. Through addressing these challenges, recent conceptual and experimental breakthroughs in the field have ushered in a world-wide effort that may be transformative for accelerators and their applications. To this end, beam-driven plasma-wakefield acceleration (PWFA) holds many potential advantages over other techniques, such as mitigated dephasing and defocussing, the opportunity for depletion studies, and the potential for immediate high-average-power plasma research. PWFA science, therefore, clearly warrants detailed investigation. The advent of experimental PWFA research in the 2000s was ushered in by the FACET and ATF facilities at SLAC and BNL, respectively. Thanks to the milestones reached by these groundbreaking experiments, additional facilities, such as the recently commissioned FLASHForward experiment at DESY -- a precision PWFA facility with FEL-quality beams and MHz rep. rate capability -- and the upcoming FACET-II -- the ultra-high peak-current successor to FACET -- will strive to make transformative leaps in the field in order to assess whether plasma-wakefield acceleration truly represents the wave of the future.
