ABSTRACT:
In an ion current control head for controlling ion current flying from an ion generation source to a dielectric medium, an electrode and electrode are each divided into a plurality of segment electrode areas, the segment electrode areas in one of these electrodes intersect those in the other electrode, and an undivided continuous electrode is provided on an ion generation source side as viewed from the electrodes. At those intersections of the segment electrode areas in the electrode and those in the second electrode, openings are provided which pierce the electrodes. An ion current control matrix drive is carried out by applying a control signal voltage across the electrodes for controlling whether ion current is flowed in the opening lor suppressed and a control signal voltage across the electrodes for controlling whether the passage of the ion current in the opening is allowed or suppressed.
