Some embodiments include a high voltage pulsing power supply. A high voltage pulsing power supply may include: a high voltage pulser having an output that provides pulses with an amplitude greater than about 1 kV, a pulse width greater than about 1 μs, and a pulse repetition frequency greater than about 20 kHz; a plasma chamber; and an electrode disposed within the plasma chamber that is electrically coupled with the output of the high voltage pulser to produce a pulsing an electric field within the chamber.
