Details of the ion simulation model. (A) A cutaway of 24 central electrodes out of 168 total. Equipotential lines corresponding to one step cycle of a 40 V applied traveling wave is indicated along the axis of the model. (B) Potential energy mesh surface illustrating the repeating pattern of traveling waves applied in the second-generation TWIMS. (C) Cutaways of the potential energy surface along the (left) lateral and (right) longitudinal directions.
