Experimental data from FACET with asymmetry in the beam-plasma system is presented. Energy dependent centroid oscillations are observed on the accelerated part of the charge. The experimental results are compared to PIC simulations and theoretical estimates. %G English %L hal-01612784 %U https://polytechnique.hal.science/hal-01612784 %~ X %~ ENSTA %~ CNRS %~ X-LOA %~ X-DEP %~ X-DEP-PHYS %~ ENSTA_LOA %~ UNIV-PARIS-SACLAY %~ X-SACLAY %~ ENSTA-SACLAY
