Three-Dimensional ICCD Observation of Dual Sustain Discharge Mode in Three-Electrode Microdischarge Cell

The spatiotemporal variations in a 3-D discharge cell are measured using infrared emission images taken with an intensified charge-coupled device (ICCD) camera. The 3-D ICCD analysis of the discharges from the conventional single surface discharge mode and a new dual surface discharge mode revealed that the discharge from the dual surface discharge mode spread toward the MgO layer in the front panel, thereby avoiding the impingement of energetic ions into the phosphor layer.
