Abstract
A system for loading a plasma charge transfer device and for holding charges applied thereto. Input and transfer electrodes are positioned on opposing walls which define a channel confining an ionizable medium. The electrodes are arranged for the application of potential differences between adjacent electrodes whereby the charges may be shifted away from the input electrode to a desired location and in a desired pattern along the length of the device. The charges are then held at the desired location by applying potential differences in a fashion such that the charge is circulated between a set of at least four sequentially positioned transfer electrodes at the desired holding location.
