In a method for increasing the kinetic energy of an ion in a linear electrode structure, axial motion of the ion is constrained substantially to a selected axial end the electrode structure. The ion is driven to move axially from the selected end toward the other end and to reflect back toward the selected end. Constraining may be effected by adjusting one or more DC voltages applied to the ends and a central region of the electrode structure to create an axial potential well in the selected end. Driving may be affected by adjusting the DC voltage applied to the selected end to a magnitude greater than the value applied during the constraining step. The constraining and driving steps may be repeated a number of times. The method may be performed in connection with collision-induced dissociation.
