    We show through experiments and supporting simulations that propagation of a highly relativistic and dense electron bunch through a plasma can lead to distributed injection of electrons, which depletes the accelerating ...
  • Beam Loading in a Proton Driven Plasma Wakefield Accelerator 
    Olsen, Veronica Kristine Berglyd (Doctoral thesis / Doktoravhandling, 2019)
    The Advanced Wakefield Experiment (AWAKE) at CERN is the first plasma wakefield experiment to exploit the self-modulation instability in a long proton bunch in order to accelerate electrons to high energies. The first run ...
