Query: Injection tolerances for AWAKE Run 2c   The AWAKE project at CERN makes use of a proton-driven plasma wakefield to
accelerate a witness electron bunch. While Run 1 relied on selective trapping
of a long electron bunch, Run~2c will use a short witness bunch to allow better
control of the accelerated bunch parameters. This work investigates the
tolerances for injection into such a quasilinear wake through simulation. A
figure of merit based on a potential high-energy application for AWAKE is
developed to provide a single metric for the accelerated bunch, allowing
different configurations to be easily compared and providing a quantitative
basis for future design decisions. Further, it is shown that the figure of
merit naturally gives rise to constraints on the tunability and stability of
the initial witness bunch parameters.
