Abstract
A microwave-plasma apparatus produces a plasma substantially at or above atmospheric pressure. A vessel contains gas substantially at or above atmospheric pressure and a plasma once initiated. Microwave energy is radiated into said vessel to produce a plasma therein. The plasma is initiated. The vessel is shaped to confine said plasma in a volume to prevent dissipation of said plasma once initiated, and the device for radiating microwave energy includes a power controller to control the power level of the microwave energy to sustain said plasma once initiated.
