Fig. 6

a Schematic representation of the ion trap with the extraction and acceleration electrodes labeled E1-E5. b Oscilloscope traces of both radio frequency phases at the time when the RF generator is switched off. The dashed line indicates the switch-off time. c High voltage pulse sequence to eject ions from the trap and accelerate them. The optimal value for Δt is dependent on the ion mass-to-charge ratio.
