Abstract :
The breakdown voltage (Vs) for a discharge in Ar at pressures between 35 and 300 torr has been reduced significantly with an array of cylindrical microdischarge devices mounted behind the tungsten cathode. For PAr = 50 torr, VS drops by approximately a factor of two, relative to that for a conventional discharge, when the microdischarge array is in operation. The injection of electron-ion pairs into the anode-cathode gap region by the array also decreases the formative and statistical time lags associated with the startup of a cold lamp
