Towards TeV electron acceleration: quasi-stable injection channels in a wakefield accelerator — •Mara Wiltshire-Turkay, John Farmer, and Alexander Pukhov — Heinrich-Heine-Universität Düsseldorf, Germany

Proton-beam-driven plasma-wakefield acceleration is a promising technique to create high-energy electrons. The large accelerating gradients possible in plasma allow the transfer of energy from TeV protons to electrons, potentially increasing achievable energies by two orders of magnitude.

Via theory and simulation, we investigate the dependence of the energy gain on the point of electron injection into the wake. We find previously unobserved complex structure of the the acceptance channels for high-energy acceleration. This result is directly applicable to the optimisation of energy gain for the planned AWAKE project at CERN.
