Notes:
Simultaneous pulsing of two, closely spaced discharge tubes inhibits the ignition of one of the discharges. Such cross-talk is prominent for discharge tubes having a floating cathode potential (i.e., with an impedance attached to the cathode), driven by short duration pulses, and having a long discharge path. The cross-talk originates from at least two mechanisms. First, a voltage jump at the cathode, induced by a capacitive coupling with another cathode, makes the anode-cathode potential smaller, and hence discharge ignition is inhibited. Second, wall charges induced by a discharge in a neighboring tube also inhibit ignition. The cross-talk can adversely affect the operation of gas discharge displays. It is demonstrated that cross-talk in the panel can be eliminated by adopting a dephasing drive technique.
