Electrical Breakdown in Water Vapor

摘要: In this paper investigations of the voltage required to break down water vapor are reported for region around Paschen minimum and left it. spite numerous applications discharges in biomedicine, recent studies bubbles with liquid electrodes, basic parameters breakdown lacking. curves have been measured by recording voltages currents low-current Townsend regime extrapolating them zero current. The electrical was found be 480 V at a pressure times electrode distance (pd) value 0.6 Torr cm (~0.8 Pa m). present measurements also interpreted using (and add additional insight into) developing understanding relevant atomic particularly surface processes associated breakdown.
