Abstract :
Artificial gas bubbles about 1 mm in diameter were generated and attached to a needle tip in n-hexane. Breakdown voltage was reduced by the presence of the bubble. Gas discharges which could be detected by a photomultiplier occurred inside the bubble. The motion of the bubble was observed by a high-speed camera. Before breakdown, a bubble moved to the plane electrode, leaving the negative needle, while the bubble never left the positive needle. The breakdown mechanism of a gas bubble n-hexane composite is discussed
