Description
AWAKE is a plasma wakefield acceleration experiment where the wakefields are driven by a long, highly energetic proton bunch that undergoes the self-modulation instability (SMI). The objectives of Run 2c, due to start in 2029, are to demonstrate emittance control of the accelerated electron bunch. Planning for this next phase is under way and includes the design of specialized experimental diagnostics for the accelerated electron bunch.
The complex setup of Run 2c, comprising two ten-meter-long plasma sections, the injection of the witness electron beam into the self-modulated proton bunch in the middle, and two possible SMI seeding methods, is simulated here with both quasistatic and fully electromagnetic particle-in-cell codes. We show the numerical results of the baseline expectation as well as parameter scans that lead to a set of requirements for the electron bunch diagnostics. Such simulations represent a key source of information for the design of plasma-based acceleration experiments.
