    Abstract: Methods and apparatus are provided for plasma-assisted processing multiple work pieces in a manufacturing line. In one embodiment, the method can include placing the work pieces in movable carriers, moving the carriers on a conveyor into an irradiation zone, flowing a gas into the irradiation zone, igniting the gas in the irradiation zone to form a plasma (e.g., by subjecting the gas to electromagnetic radiation in the presence of a plasma catalyst), sustaining the plasma for a period of time sufficient to at least partially plasma process at least one of the work pieces in the irradiation zone, and advancing the conveyor to move the at least one plasma-processed work piece out of the irradiation zone. Various types of plasma catalysts are also provided.

    Abstract: Methods and apparatus are provided for igniting, modulating, and sustaining a plasma for various plasma processes and treatments. Such treatments include cleaning and sterilizing parts. In some embodiments, a plasma is ignited by subjecting a gas in a multi-mode processing cavity to electromagnetic radiation having a frequency between about 1 MHz and about 333 GHz in the presence of a plasma catalyst. A part can be cleaned by, for example, inserting hydrogen into the plasma and exposing the part to the hydrogen-enriched plasma. A part can be sterilized by heating the part with the plasma.
