Description

In plasma-based acceleration, an ultra-relativistic particle
bunch—or an intense laser beam—is used to expel electrons
from its propagation path, forming a wake that is devoid
of electrons. The ions, being significantly more massive,
are often assumed to be stationary. However, both theory
and simulations suggest that any sufficiently dense electron
bunch can trigger ion motion, and its effect must be taken
into account. We simulate beam-driven plasma wakefields
to identify key features—such as longitudinally dependent
emittance growth—that could be observed in an experiment
using plasma and beam parameters from the FLASHForward
facility at DESY.
