Abstract
An apparatus for transporting charged particles in a predetermine path which includes a donor member that is adapted to move charged particles on the surface thereof in the predetermined path. The donor member includes an electrode array on the outer surface thereof; the array including a plurality of spaced apart electrodes extending substantially across width of the surface of the donor member. A multi-phase DC voltage source is operatively coupled to the electrode array, the phase being shifted with respect to each other such as to create an electrodynamic wave pattern capable of moving charged particles on the surface thereof in the predetermined path.
