Abstract
Experiments and simulations are reported for a monolayer plasma crystal that is disturbed by an extra particle moving in a plane below the monolayer. Numerical simulations and experiments are performed to find an explanation for the motion of the extra particle. The simulations take into account the ion wakefield downstream of the monolayer of particles, in the presence of ion flow. In the experiment, the orbit is straight at low gas pressures, but with higher damping it is crooked and less energetic. The same trend is observed in the simulations, supporting a conclusion that the wakefield is responsible for the particle acceleration. The simulation reveals that the energy of the extra particle exhibits distinctive transitions, between three regimes.
