Abstract
The present disclosure is generally directed to a plasma sheet source and methods of using same. The plasma sheet source includes a cylindrical electrode having a conductive cylindrical core surrounded by a dielectric material, a plurality of channels configured to direct gas from a gas inlet to the electrode, and a plasma outlet positioned below the electrode. Gas is introduced to the plasma sheet source and directed toward the electrode, which when powered by pulsed direct current, produces plasma as the gas ionizes. The produced plasma is then directed out of the plasma outlet to a specimen for treatment of the specimen. Notably, the plasma exiting the plasma outlet is in the form of a plasma sheet that is at approximately room temperature.
