Abstract
A low power pulsed corona discharge has been created in liquid media. The corona is generated at the similar to 1 mu m sharp tip of a tungsten wire submerged in the liquid. The voltage pulse of about 15 kV applied to the tip is generated using spark gaps in air resulting in a rise time of similar to 300 V/ns. During this voltage pulse a small bubble and light emission is visible from the wire tip. The color of light emission depends on the liquid media. Optical emission spectroscopy is used to analyze the light emitted by the discharge. Due to the small size the plasma electron density is several orders of magnitude lower than for larger scale pulsed coronas and may remain non-thermal. Tested liquids include tap water and aqueous salt solutions. The light emission is unique to the constituents of the liquid in which the discharge is created. These preliminary results indicated that this corona in liquid may be a unique tool for the diagnostics of liquids such as species and contaminant detection.
