摘要： A dielectric barrier plasma discharge device consistent with certain embodiments of the present invention has a pair of electrodes spaced apart by an electrode gap. A dielectric is disposed between the electrodes. The electrode gap is provided with a gas at a specified pressure. A rapid rise time voltage pulse generator produces a voltage pulse across the electrodes to cause an extreme overvoltage condition, wherein the rapid rise time is less than a plasma generation time so that the extreme overvoltage condition occurs prior to current flow across the electrode gap. Due to the high voltages and high current densities, the product yields an extremely high instantaneous power density. This extreme overvoltage condition is also believed to lead to production of shock waves and runaway free electrons. The resulting plasma can be utilized to carry out many potential tasks including, but not limited to etching, deposition, and sterilization. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： A method of generating a fast-rise time voltage step to produce an overvoltage condition for a dielectric barrier plasma discharge involves providing a pair of electrodes spaced apart by an electrode gap and at least one dielectric disposed in the gap; generating fast-rise time voltage step such that the rise time to achieve said overvoltage condition is equal to or less than the time required to generate the plasma thereby establishing the overvoltage condition prior to current flow across said electrode gap. Power from storage capacitor banks discharge into the electrode gap through a switch. The switch is capable of standing-off voltage sufficient to create the overvoltage condition when the switch is open. The discharge current pulse across the said electrode gap is terminated by charging properties of the said dielectric(s) in the said electrode gap. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
